Keys and Display Messages Keys and indicators that are labeled on the printer are printed in uppercase. Example: Press the ON LINE key. Messages that appear on the Liquid Crystal Display (LCD) are enclosed in quotation marks and printed with initial capital letters. Example: The message “Save Config” appears on the display. Related Documents For more information about your printer, refer to the following documents: Introduction • P4280 Line Matrix Printer Operator’s Guide.
The P4280 Line Matrix Printer The P4280 printer incorporates the latest refinements in line matrix printing technology, yet is very easy to use. The LCD and Light Emitting Diodes (LED) status indicators on the control panel communicate with you directly and clearly. You can select every function on your printer at the control panel or by sending commands from the host computer.
Standard Features General • Quiet operation • Print speeds of up to 800 lines per minute (lpm) Host Computer Interface • Dataproducts-compatible parallel interface • Centronics-compatible parallel interface • RS-232 serial interface Printer Command and Control • Three printer emulations are selectable at the control panel and controlled by software: 1) Printronix P-Series emulation 2) Printronix P-Series XQ emulation 3) Serial Matrix printer emulation (similar to the IBM Graphic Printer, but wit
• Character attribute specification: 1) Selectable pitch: normal, expanded, and compressed 2) Emphasized (“shadow”) printing 3) Double strike (bold) printing 4) Automatic underlining 5) Superscript and subscript printing 6) Double high printing • Resident multinational character sets • Downloadable character sets and international languages. You can add international languages to the font library and access them in both P-Series and Serial Matrix emulations.
Optional Features We offer a variety of options that enable you to fine-tune your printer to nearly any printing application: • Intelligent Graphics Processor (IGP–200 and IGP–210). The IGP processes and plots all graphics, freeing the host computer for other tasks. You can create forms, bar codes, logos, expanded characters, and other graphics. You can print sideways or upside down. You can print forms with graphic components overlayed with alphanumeric and bar code data, all in a single pass.
Protocols and Emulations Protocols A protocol is a set of rules governing the exchange of information between the printer and its host computer. These rules consist of codes that manipulate and print data and allow for machine-to-machine communication. A printer and the its host computer must use the same protocol. Most impact printers use single ASCII character codes to print text, numbers, and punctuation marks. Some characters, both singly and in groups of two or more, are defined as control codes.

Overview IMPORTANT Configuration directly affects printer operation. Do not change the configuration of your printer until you are thoroughly familiar with the procedures in this chapter. In order to print data, the printer must respond correctly to signals and commands received from the host computer. Configuration is the process of matching the printer’s operating characteristics to those of the host computer.

Operating States The printer has two operating states: on-line and off-line. When the printer is on-line, it is controlled by the host computer and prints data sent by the host computer. In the off-line state, communication with the host is interrupted so that you can load paper, change ribbons, or test and configure the printer. NOTE: When the printer is on-line, it may display an “L” in the lower right corner of the message display, or an “E” in the upper right corner.
Unlocking the ENTER Key To change a parameter, such as line spacing, you must unlock the ENTER key. With the printer off-line, raise the printer cover and press the Y and B keys at the same time. The following control panel message appears for about a second: ENTER Switch Not Locked Although all menus and settings are accessible in the off-line state, the printer is in “Configuration Mode” only when the ENTER key is unlocked.
Saving Parameters You can change a parameter, such as line spacing or form length, by pressing keys on the control panel or by sending control codes from the host data stream. Your programming reference manual provides information about control codes. Once you change a parameter, it is active as long as the printer is on. This is true whether you use the control panel or send a control code from the host.
Factory Default Configuration Values The printer is configured at the factory as shown in Table 3–1. All of the values are permanently stored in ROM and are easily reloaded. To load the factory default values, use the Load Parameters menu (page 3–19), or reset the printer (page 3–23) if the Factory Default is the designated power–up. Table 3–1.

Changing Configuration Values Application Compatibility Paper Format Line Spacing Form Length Set Auto Line Feed Set at 6 LPI Set at 8 LPI Set at 10.3 LPI A configuration consists of several parameters. The printer contains four predefined configurations (IGP, IBM 3287, IBM 5225, and the factory default), which cannot be altered. However, you can change the four customized configurations to meet different print job requirements.
Step Press Result Notes 1. Make a configuration printout. Refer to “Printing the Current Configuration” on page 3–12. You may skip this step. 2. Determine which parameters you want to change, and what their new values should be. (In this example, we are changing the value of the Line Spacing parameter from “Set at 6 LPI” to “Set at 8 LPI”.) 3. Press: 4. ON LINE Off–Line Ready 1 The printer must be off-line to change the configuration. Raise the printer cover.
Step Press 11. 12. OR ENTER Result Notes Cycle through the values (6, 8, or 10.3 LPI). Line Spacing Set at X LPI * Selects the displayed value. Asterisk (*) appears, indicating this value is active. Line Spacing Set at 8 LPI * 13. Continue this pattern to make other changes. 14. All changes remain in memory until you turn the printer off. If you want to save these changes as a configuration that is stored in memory and can later be loaded, go to page NO TAG.
Saving Your New Configuration Save Parameters X Save Parameters Values Saved X = Current Configuration Once you have changed all of the necessary parameters, it is recommended you save them as a configuration that can be stored and loaded later for future use. You can save up to four configurations to meet different print job requirements.
Step 1. Press Ribbon Life 3. UNTIL 4. ENTER 5. CLEAR 9. 3–18 X = the current configuration. Save Parameters X Displays for about one second. The printer has stored the new parameters in NVRAM as power-up default values. Save Parameters Values Saved Off–Line Ready X X = the current configuration. To make a printout of your configuration, go to page 3–12, step 4. If you decide not to print the configuration, then continue with the following steps. 7. 8.
Loading Predefined Configurations Load Parameters Load Saved Parameters 1 Load IGP Parameters Load IBM 3287 Parameters Load IBM 5225 Parameters Load Factory Parameters Use this procedure to load the factory, IGP, IBM 3287, or IBM 5225 configurations. These configurations are stored on ROM and cannot be altered. See Appendix D. Although you can use this procedure to load one of the customized configurations, it is recommended you use the CONFIG key (page 3–22).

Loading Customized Configurations CONFIG Figure 3–3. The CONFIG Key A configuration contains a group of parameters that are set to particular values. You can customize up to four unique configurations to meet specific job requirements. Pressing the CONFIG key allows you to select and load one of the four customized configurations quickly. Each time you press CONFIG, it selects and loads a configuration. For example, if Configuration 1 is loaded and you press CONFIG, Configuration 2 is selected and loads.
Resetting the Printer to Default or Saved Parameters Printer reset is also called initializing the printer. This procedure clears RAM and loads either the factory configuration parameters or a set of parameters you have saved previously. Factory parameters are permanently stored in ROM. However, if you have saved a set of configuration parameters, your most recently saved set loads when you reset the printer.
Configuration Menu Diagrams The Configuration Menu diagrams on the following pages show the structure of the configuration menus and the parameters available in each menu. The diagrams list the menus and options in the order they appear on the control panel. NOTE: In the following descriptions, hexadecimal (hex) values are shown for some ASCII codes, such as command delimiters.

Application Compatibility (From page 3–25) Printer Protocol Uppercase Select * P–Series Serial Matrix P–Series XQ * 2048 Characters 512 Characters 1024 Characters * Upper & Lower Alarm On Fault Shuttle Timeout Unidirectional * Enable Disable Control Code 08 * Buffer Size Double High Backspace * 4 Seconds 10 Seconds . . 300 Seconds (Timeouts range from 10 to 300 in increments of 5 seconds.
Printer Protocol The Printer Protocol parameter enables you to set the desired printer emulation. • P-Series: Standard Printronix P-Series emulation. The command delimiter is an ASCII code that is configured from the control panel via the Select SFCC parameter. (The ASCII Code SOH (01 hex) is the default command delimiter. See the description of the Select SFCC parameter on page 3–38.) • Serial Matrix: IBM Graphics Printer emulation; uses ASCII Code ESC (1B hex) as a command delimiter.
Uppercase Select The Uppercase Select parameter controls how the printer handles lowercase characters it receives from the host computer. • Upper & Lower: The printer prints lowercase characters received from the host computer as lowercase, and uppercase characters received from the computer as uppercase.
Paper Advance SW (Switch) The Paper Advance SW parameter controls the action of the Form Feed (FF) key on the printer’s control panel when the printer is off-line. • Print + Pap Adv: If there is no data in the printer’s internal input buffer and you press the FF key, the paper immediately advances to top-of-form. If there is unprinted data in the buffer when you press the FF key, the printer first prints the data and then advances the paper only to the next print line.
Alarm On Fault The Alarm On Fault parameter determines whether or not the audible alarm sounds on a printer fault, such as an out-of-paper condition. If Alarm On Fault is enabled, the alarm sounds when a printer fault occurs. You can enable or disable this parameter. Shuttle Timeout The shuttle timeout parameter determines the amount of time the shuttle will continue running after printing stops.
Select SFCC The Select SFCC feature allows you to select which ASCII codes will function as the command delimiter (Special Function Control Character). • SOH (01 hex) • ETX (03 hex) • ESC (1B hex) • CIRCUMFLEX (5E hex) — also called caret or “hat” (^) • TILDE (7E hex) — (~) • TILDE, RIGHT BRACKET (7Eh 5D hex) — (~]) NOTE: SOH, ETX and ESC are non-printable (control) characters.
Control Code 08 The Control Code 08 feature defines the function of ASCII code 08 hex (BS). You can select a Backspace function or a Double High (elongated) print function. NOTE: The Control Code 08 parameter is available only when the P-Series Printer Protocol has been selected.
Compress Print Compressed print characters are narrower than the normal character set. This is helpful for applications where you need to print the maximum amount of information on a page. The Compress Print parameter controls which host command sets compressed printing. • SOH (01 hex) • ETX (03 hex) • HT (09 hex) NOTE: The Compress Print parameter is available only when the P-Series XQ Printer Protocol has been selected.
Font Select / Elongated The Font Select / Elongated parameter controls how the printer interprets the hex codes 08 and 0E. • Font Select = 0E and Elongated = 08: The printer interprets the code 0E hex in the data stream from the host computer as a Font Select command; it interprets 08 hex as an Elongated Print command. • Font Select = 08 and Elongated = 0E: The printer interprets the code 08 hex from the host as a Font Select command; it interprets 0E hex as an Elongated Print command.
Paper Format Menu Options Paper Format (From page 3–25) Line Spacing Form Length Set * Set at 6 LPI Set at 8 LPI Set at 10.3 LPI In Inches In 6 LPI Lines * 11.0 Inches * EVFU DVFU NVFU CVFU Disable Slew Relative * 1 to 16 1 to 15 VFU Table * Clear Save Set Platen @ BOF * Disable Enable (Value range is from 1 to 192 lines in 1 line increments.) * LF = CR + LF LF = LF CR = CR + LF * 88 Lines (Value range is from 1 to 192 lines in 1 line increments.
Line Spacing The Line Spacing feature sets the number of lines to be printed per inch (lpi). At 6 lpi, for example, print lines are spaced 1/6-inch apart. • Set At 6 LPI • Set At 8 LPI • Set At 10.3 LPI Form Length Set The Form length feature sets the number of lines that can be printed on a page. You can set form length in inches or in print lines per page, at either 6 or 8 lines per inch (lpi).
Auto Line Feed The Auto Line Feed feature may be enabled to prevent data from being “lost” beyond the right margin. When the right margin is reached, a Line Feed code (0A hex) is inserted into the data stream, causing the remaining data to print on the next line. • After Full Line: The feature is enabled; the printer inserts an extra Line Feed after each full line of text. • Disable: The feature is disabled.
VFU (Vertical Format Unit) Select The VFU Select feature controls how the printer handles vertical formatting. • EVFU: Enables the VFU and selects Printronix P-Series compatible Electronic Vertical Format Unit (EVFU). • DVFU: Enables the VFU and selects Dataproducts-compatible Direct Access Vertical Format Unit (DAVFU). • NVFU: Enables the VFU and selects Printronix P-Series compatible New direct access Vertical Format Unit (NVFU).
VFU (Vertical Format Unit) Table The VFU Table feature controls how the printer handles the VFU formatting information, which is stored in RAM. Either the VFU information can be cleared or it can be saved to NVRAM. • Clear: With “Clear” displayed, press ENTER to discard the loaded VFU data. • Save: With “Save” displayed, press ENTER to save the current VFU data in NVRAM. This data will be loaded into the VFU when the printer is reset or turned on.
Paperout Adjust The Paperout Adjust feature allows you to adjust the Paper Out distance from the perforation; that is, the last dot row on the page that will print when there is a Paper Out condition. CAUTION If the printer runs out of paper and this parameter is set incorrectly, the printer may print on the platen. VORSICHT Falls das Druckpapier ausgeht und dieser Parameter falsch eingestellt ist, kann es vorkommen, daß der Drucker auf die Druckwalze druckt.
PRÉCAUTIONS Lorsque la fonction PMD est désactivée, le déplacement du papier n’est plus contrôlé. L’imprimante ne signale plus les bourrages papier et continue l’impression, ce qui risque de l’endommager. Slew Relative The Slew Relative feature determines the number of lines slewed when an EVFU Slew Relative command is received. For further information, refer to the EVFU information in the Programmer’s Reference Manual.
Slow Paper Slew When enabled, the Slow Paper Slew option slows the rate at which paper advances into the stacking area of the printer. This option may be used if the paper slew speed is too fast to allow the paper to stack properly. • Enable. Causes the printer to advance the paper at a slower speed. • Disable. The default. The printer advances the paper at the maximum speed.
Host Interface Menu Options Figure 3–10 shows the Host Interface Menu. From this menu, you can select one of three types of interface between the printer and your host computer: • Centronics: Selects a Centronics parallel interface. • Dataproducts: Selects a Dataproducts parallel interface. • Serial RS-232: Selects an EIA-232 (EIA RS-232) serial interface. Each of the three types of interfaces has its own set of parameters.
Centronics Menu Options *Centronics (From page 3–50) Data Bit 8 * Enable Disable PI Line *Disable Enable Fast Busy *Enable Disable Data Polarity Resp.

Data Bit 8 The Data Bit 8 parameter allows access to the extended ASCII character set. Normally, this parameter is enabled. When this parameter is disabled, the printer interprets bit 8 of each incoming data character as a zero, regardless of its actual setting. PI (Paper Instruction) Line The Paper Instruction Line parameter controls how the printer interprets the PI line on the Centronics parallel interface from the host computer. The PI line is a signal from the host that controls vertical paper motion.
Data Polarity The Data Polarity parameter can be set to Standard or Inverted. It must be set to match the Data Polarity of your host computer. • Standard: The printer does not invert the data. • Inverted: The printer inverts the data it receives on the data lines from the host computer. Ones become zeros, and vice-versa. Response Polarity The Response Polarity parameter can be set to Standard or Inverted. It must be set to match the Response Polarity of your host computer.
Strobe Polarity The Data Strobe Polarity parameter can be set to Standard or Inverted. It must be set to match the Data Strobe Polarity of your host computer. When the host computer sends a data strobe signal to the printer, this enables the printer to read the data bus. • Standard: The printer does not expect the data strobe signal to be inverted. • Inverted: The printer expects the host computer to invert the data strobe signal.

Data Protocol The Data Protocol parameter selects one of several different serial interface protocols. These protocols provide for flow control and other host interface requirements. These are discussed on page 4–11 in Chapter 4, Printer Interfaces. • X-ON/X-OFF • ACK/NAK • ETX/ACK • DTR, RC, or RTS IMPORTANT When the Data Protocol parameter is set either to the ACK/NAK protocol or to the ETX/ACK protocol, the protocol consumes all ETX characters.
Stop Bit The Stop Bit parameter sets the number of stop bits in the serial data word. Either one or two stop bits can be selected. The setting must match the corresponding stop bit setting in the host computer. Parity The Parity parameter can be set for odd parity, even parity, or no parity. The setting must match the corresponding parity setting in the host computer. Parity error handling is discussed further on page 4–12 in Chapter 4, Printer Interfaces.
Data Term Ready The Data Term Ready parameter selects how the printer controls the Data Terminal Ready (DTR) signal. DTR is a control signal from the printer to the host computer indicating whether or not the printer is ready to receive data. You should set this parameter according to the manner in which the host computer uses DTR. • On-Line and BNF: The printer asserts DTR whenever it is on-line and its internal input buffer is not full (BNF).
Reverse Channel The Reverse Channel parameter selects how the printer controls the Reverse Channel (RC) signal. RC is a control signal from the printer to the host computer indicating whether or not the printer is ready to receive data. You should set this parameter according to the manner in which the host computer uses RC. 3–62 • On-Line and BNF: The printer asserts RC whenever it is on-line and its internal input buffer is not full (BNF).
Load Parameters Menu Options You can load one of four sets of previously-saved parameters, one of three sets of permanently-stored factory-set parameters, or the permanently-stored factory-set default parameters, as needed, into the currently-selected configuration (1, 2, 3, or 4). (Also see “Loading Configuration Values” on page 3–19.
Load Saved Parameters (1, 2, 3, or 4) NOTE: Although you can use this menu to load customized configurations, it is recommended you use the CONFIG key. See page 3–22. Pressing ENTER when this message displays loads the first (or second, third, or fourth) set of parameters you saved previously. After you press ENTER, the message “Load Saved Completed” will display for about one second. Then, the display returns to the “Load Saved Parameters” menu.
Load Factory Parameters Pressing ENTER when this message is displayed loads the permanently-stored factory-set default parameters (also called the “factory default” parameters). After you press ENTER, the message, “Load Factory Completed” will be displayed for about one second. Then, the display returns to the “Load Factory Parameters” menu.
Save Parameters Menu Options You can save up to four configurations to meet different print job requirements. A configuration consists of several parameters. They will be saved into the currently loaded configuration (1, 2, 3, or 4). (Also see “Saving Your New Configuration” on page 3–17.) The parameters are stored in non-volatile memory (NVRAM), so they are not lost if you turn off the printer. NVRAM is divided into four blocks, each of which stores a different configuration.
Diagnostics Menu Options Diagnostics (From page 3–25) Configuration Printout Press ENTER to print the configuration Print Datastream in Hex.
The Diagnostics Menu allows you to do the following: • Print out a listing of the current printer configuration. • Print out the hexadecimal code values of characters received from the host computer. • Run various printer tests. • View certain printer statistics on the printer’s control panel message display.

Overview The printer interface is the point where the data line from the host computer plugs into the printer. The interface processes all communications signals and data to and from the host computer. The printer interface consists of a printed circuit board assembly (PCBA) and a cable connector for the data line. Communication signals and data may be sent over parallel or serial lines. The printer is equipped with two parallel interfaces and a serial interface.
Dataproducts Parallel Interface The Dataproducts parallel interface allows the printer to operate with a 50-pin AMP Ampilite HDH-20 data cable connector. The length of the data cable from the host computer to the printer must not exceed 40 feet (12 meters). An adapter cable to accept the 50-pin Winchester MRAC50P connector is also available from your authorized service representative. Table 4–1.
Dataproducts Parallel Interface Signals Table 4–1 lists the Dataproducts interface connector pin assignments. Dataproducts-compatible interface signals between the computer and the printer are defined as follows: Data Lines 1 through 8 — Eight standard or inverted levels from the host that specify character data, plot data, or a control code. Sensing Data Line 8 is controlled by printer configuration. Data Strobe — A high true pulse from the host to indicate that data is ready.
Dataproducts Parallel Interface Configuration The printer is configured at the factory to match the interface specified by the customer. You can also configure the printer via its control panel.
Centronics Parallel Interface The Centronics parallel interface enables the printer to operate with controllers designed for buffered Centronics printers. The length of the data cable from the host computer to the printer must not exceed 15 feet (5 meters). Table 4–2.
Centronics Parallel Interface Signals Table 4–2 lists the Centronics interface connector pin assignments. Centronics-compatible interface signals between the computer and the printer are defined as follows: Data Lines 1 through 8 — Eight standard or inverted levels from the host that specify a character or function code. Sensing Data Line 8 is controlled by printer configuration. Data Strobe — A low true, 100 ns min. pulse from the host that clocks data into the printer.
Centronics Parallel Interface Configuration The printer is configured at the factory to match the interface specified by the customer. You can also configure the printer via its control panel.
Alternate Terminating Resistors The factory equips the printer with 470 ohm pull-up and 1K ohm pull-down terminating resistors, located at coordinates 12C and 12D respectively on the Common Controller Board (CCB). These resistors are used for parallel interface configurations and are suitable for most applications.
RS-232 Serial Interface The RS-232 Serial interface enables the printer to operate with bit serial devices compatible with an RS-232D controller. The interface circuit characteristics are compatible with the Electronic Industry Association Specification EIA-232-D. Input serial data transfer rates of 150, 300, 600, 1200, 2400, 4800, 9600, and 19200 baud are selectable at the control panel. The input format consists of a single start bit, 7 or 8 data bits, and one or two stop bits.
Transmitted Data — Serial data stream from the printer for transmitting status and control information to the host. Subject to protocol selection. Request To Send (RTS) — Control signal from the printer. Subject to configuration. Clear To Send (CTS) — Status signal to the printer indicating the host is ready to receive data/status signals from the printer. This signal is ignored in the printer. Data Set Ready (DSR) — Status signal to the printer indicating the host is in a ready condition.
with an End of Text (ETX) signal. When the printer receives the ETX, it will acknowledge the ETX, thereby acknowledging it has received the entire block of data. DTR (Data Terminal Ready), RC (Reverse Channel), or RTS (Request to Send) — Control signals from the printer to the host computer. (Subject to configuration.) Configurations include: always true, always false, true if on-line and buffer not full, and true if off-line or buffer almost full.
RS-232 Serial Interface Configuration The printer is configured at the factory to match the interface specified by the customer. You can also configure the printer via its control panel.

Overview This chapter discusses general cleaning, running diagnostic tests, and understanding fault messages. The printer requires no routine maintenance beyond regular cleaning. Periodically remove excess paper chaff and dust from the ribbon and paper paths. If print quality or paper motion deteriorates seriously even after cleaning, contact your authorized field service representative for prompt attention. Cleaning Requirements Periodic cleaning ensures efficient operation and clear print quality.
Cleaning Inside the Cabinet Over time, particles of paper and ink accumulate inside impact printers. This is normal. Paper dust and ink build–up must be removed periodically to avoid degraded print quality. Most paper dust accumulates around the ends of the platen and ribbon path. To clean the interior of the printer, refer to the following steps: 1. Power off the printer and unplug the printer power cord. 2. Unload the paper (explained in the Operator’s Guide). 3.
4. Using a soft–bristled brush and vacuum cleaner, brush and vacuum paper and dust particles from the paper path, ribbon guides, ribbon path, and base pan. IMPORTANT Vacuum carefully around the hammer bank and surrounding area to avoid damage. 5–4 5. Check the ribbon mask and hammer bank cover for pieces of torn paper or ribbon lint. Check the holes in the ribbon mask surrounding each hammer tip. Gently remove paper or lint particles with a wooden stick or pair of tweezers.

Diagnostic Tests With the exception of testing the interface between the printer and the host computer (and the associated data cable), you do not need to send data from the host computer to the printer to test printer operation. You can use the printer built-in diagnostic tests to check many of the functions of your printer, including print quality and overall operation. Diagnostics (From page 3–25) Configuration Printout Press ENTER to print the configuration Print Datastream in Hex.
The following diagnostic tests are available: • Shift Recycle A “sliding” alphanumeric pattern used to identify missing or malformed characters, improper vertical alignment, or vertical compression. • All E’s A pattern of all uppercase letter E’s used to identify missing characters, misplaced dots, smeared characters, improper phasing, or light/dark character variations.
• Paperout Adjust A pattern used to determine the number of dot rows from the completion of a paper out fault to the end of the paper. • Demo A text and graphics pattern that illustrates many of the printer’s features. This test can also be used to identify phasing problems within different character pitches and font styles. • Phase Adjustment A timing test used by qualified service personnel to adjust vertical alignment of dots in character printing.

Overview This chapter explains how RibbonMinder works and how to configure it to meet your specific print job requirements. RibbonMinder is a user–definable software feature that determines when a ribbon should be changed. It monitors ink consumption and alerts you when the print quality falls below a level that you designate. This is especially important if you are printing bar codes to be scanned. NOTE: RibbonMinder does not use any hardware within the printer to detect print density problems.
Running a Job Once you have set up your parameters for RibbonMinder, it works without attention. Normally, you only need to select the RibbonMinder configuration menu to install a new ribbon, change job rates or ribbon size, or to disable/enable RibbonMinder. When you begin printing with RibbonMinder enabled, the message display shows a ribbon life value of 100%. The ribbon life value decreases as the ink is consumed. You can use the RibbonMinder feature to run more than one job on the same ribbon.
Configuring the RibbonMinder The following procedures explain how to set each RibbonMinder parameter and either exit the configuration menu or continue to the next parameter. Parameters are presented in the order in which they are usually configured the first time. NOTE: When you make changes to RibbonMinder parameters, your changes are saved automatically in NVRAM (Non–Volatile Random Access Memory). As you perform the following steps, refer to the RibbonMinder Menu Diagram shown in Figure 6–1.
Ribbon Life (From page 3–25) New Ribbon Analyze Job Set Job Rate Press ENTER to reset ribbon life to 100%. A new ribbon must be installed after setting the ribbon life to 100%. Currently xxx New Rate yyy Press " or A to increase or decrease New Rate by 1 Press ENTER to enter the Analyze Job mode.
Setting Up a New Ribbon The New Ribbon parameter allows you to reset the ribbon life after replacing a worn ribbon. Also follow this procedure when first setting up RibbonMinder parameters. Note that it may be necessary to replace ribbons before the ink has been depleted. This may occur with ribbons that have been snagged, folded, or otherwise damaged.
Step Press Result Notes 8. Remove the old ribbon and install a new one (see the Operator’s Guide). If you try to print before changing the ribbon, the printer displays the fault message, “Fault Condition, Change Ribbon”. 9. To set or change the ribbon size, go to page 6–8, step 4. Otherwise, continue with this procedure to exit. 10. CLEAR 11. 12. Off–Line Ready + xxx% 1 Locking prevents settings from being changed. ENTER Switch Locked Close the printer cover. 13.

Analyzing Jobs The Analyze Job parameter allows you to enter the job analysis mode to determine job rates for various print jobs. The job rate is the rate at which a particular print job or collection of jobs wears out the ribbon. To determine the rate for a new print job using analyze mode, you must install a new ribbon, analyze the job, and set the job rate. NOTE: You may set the job rate without using analyze mode. Refer to page 6–18.

The message display shows the analyze rate instead of the “Ribbon Life” percentage. 12. Begin printing a job. The analyze job rate number begins at 1000 and decreases as the ribbon becomes worn. With a new 60–yard ribbon, the rate begins decreasing when more than 200 pages are printed. 13. The same job can be printed repeatedly to compute a job rate.
Analyzing Jobs Quickly To analyze a job without running the entire ribbon, follow these steps: 1. Generate a sample printout of the job. 2. Find the vertical dot column with the most printed dots. Count the number of dots printed in the dot column. 3. Compute the total number of dots that could have been printed in the dot column. Do not count the horizontal dot rows that are not printed due to paper movement (horizontal dot rows without dots).
Setting the Job Rate The Job Rate parameter describes the rate at which a particular print job wears out the ribbon. Values can range from 0 (no wear) to 1000 (the highest possible rate of ink usage). The job rate must be set in order for the RibbonMinder to work correctly. When setting the job rate, remember: • Job rates must always be determined prior to running a job. • Job rates do not change when the ribbon size changes. (The Ribbon Size parameter must be reset when the size of the ribbon changes.

RibbonMinder Host Data Stream Commands In addition to controlling the RibbonMinder feature from the printer’s control panel, you can also control RibbonMinder from the host computer by sending control code sequences to the printer. NOTE: The host commands “Set Job Rate,” “When Worn Action,” and “Enable/Disable” supply values to the RibbonMinder features. For proper operation, if you are using these commands, you must send them to the printer prior to printing data.

Character Formation The P4280 is an impact printer: It creates characters by printing ink dots on paper. Dots overlap to produce a solid-appearing character of uniform density. The dots are made by an assembly of steel hammers mounted on a rapidly oscillating shuttle. The hammers strike the paper through a moving ink ribbon. The dot patterns of characters are mapped in printer memory on invisible matrixes, as shown in Figure B–1.
Serial matrix printers use a moving printhead with pins to form single characters sequentially along the printed line. Unlike serial matrix printers, the P4280 is a line matrix printer. Line matrix printers divide every printable line into horizontal dot rows, then print a dot row of the entire line at every lateral sweep of the shuttle. During each sweep of the shuttle, hammers are activated to print dots at the required positions in the dot row.
Printing Speed The speed of text printing is measured in lines per minute (lpm). This speed is dependent upon the number of dot rows required to produce a line of characters, regardless of the number of characters in the line. Because more dot rows are required to print lowercase characters with descenders, those character lines will print at a fractionally lower rate. In addition to character printing, the printer can plot dot-addressable graphic images.

The height of a cell is equal to the current line spacing, and the width is equal to the current character spacing. Used as a unit of spacing. character proportion The ratio of character height to character width. See also compressed and expanded.
compressed Refers to a typeface with a font width approximately 60% smaller than normal. Character height is not changed. configuration Refers to the operating properties that define how the printer responds to signals and commands received from the host computer at the printer interface. These properties are called configuration parameters and must be set to match the operating characteristics of the host computer system.
