3.8 SELF TEST A document may be test printed by pressing 9 1 FUNCT. SELF TEST is displayed until a document is inserted. Then CHAR LENGTH = 30 is displayed. Press A to select CHAR LENGTH = 80. (30 characters requires a document at least 3 1/2" wide, 80 characters requires 8 1/2".) Do not print across a vertical fold or document edge. Press ENTER to print the top and bottom lines of the document and then eject it. 3.
3.11 DP6 & DP7 PROGRAMMING CAUTION: DURING PROGRAM DEVELOPMENT ALL PRINTING SHOULD BE DONE ON SINGLE SHEET PAPER UNTIL PRINT FIELDS ARE CORRECTLY FORMATTED. PRINTING DIRECTLY ACROSS THICK FOLDS AND DOCUMENT EDGES CAN DAMAGE THE PRINTHEAD. The printer accepts two separate command sets, C and I, that are selectable either from the keypad using 9 3 FUNCT (see 3.6.2) or the interface. Mode C is compatible with previous versions of this printer while Mode I is compatible with popular PC based printers.
3.11.2 Mode C Document Movement Commands BS or ESC ] moves the document down one line, with line spacing keypad selected (see 3.6.1) or set by an HT command. LF moves the document up one line, with line spacing keypad selected (see 3.6.1) or set by an HT command.
3.11.4 Mode C Display Commands BEL immediately displays the following 16 characters on the upper line of the alphanumeric display. The characters must not be control characters and there must be exactly 16 displayable characters. FS loads the lower display line just like BEL loads the upper line. DC3 or ETB operate identically to a BEL command but all previously received print and document movement commands are executed before the upper line of the display is loaded.
3.11.6 Mode C Status and Keypad Commands Status, key buffer contents, line count or document length data are transmitted when requested by the host. ENQ requests printer status and is executed when it is received. SUB also requests printer status but it is executed identically to an ENQ only after all previously received commands have been executed. SUB may be used to interrupt the host and notify it that the printer is now idle.
3.11.7 Mode C Graphics Commands Dot addressable graphics may be printed at 60 or 120 dots/inch (dpi) horizontally by 72 or 144 dpi vertically. ESC A must precede each line of 60 dpi data with a maximum of 480 data bytes. ESC B must precede each line of 120 dpi data with a maximum of 960 bytes. Each line of data must be terminated by a feed command, usually a VT e, ESC 1 or ESC 9.
3.12.
Commands prefixed with a * will not be executed until after an ESC ENQ is received if the BLOCK protocol is used. ESC ENQ's are not required if DTR or XON/XOF protocols are used. 3.12.2 Mode I Document Movement Commands LF moves the document up one line, with line spacing keypad selected (see 3.6.1) or set by an ESC 0,1,2 or 3 command. ESC 0 sets line spacing to 1/8 inch. ESC 1 sets line spacing to 7/72 inch. ESC 2 sets line spacing stored by a prior ESC A n.
ESC [ @ followed by 04 00 00 00 m n hex selects double high and wide print. Double high print is set if the low order nibble of m is 2 and single high is set if it is 1. Double line feeding is set if the upper nibble of m is 2 and single line feeding is set if it is 1. Double wide print is set if n is 2 and single wide is set if it is 1. ESC : starts 12 character/inch printing. SI starts 17.1 character/inch printing. DC2 stops 12 or 17.1 character/inch printing and returns to 10 cpi.
1B 4B 10 00 00 00 00 00 00 00 00 00 80 40 20 10 08 04 02 01 0A The DP7 accepts ESC K, L and Y commands. These and other graphics modes are also selected by an ESC [ g m n p where m + 256 X n is the following graphics data byte count plus one and p selects graphics densities as follows: p value: 0 Density: 60x72 1 2 120x72 120x72 8 60x180 9 120x180 11 180x180 12 360x180 In the 180 dpi vertical modes, each group of 3 following graphics data bytes will be printed as one 24 dot vertical stroke. 3.
movement command is received. Transmission from the host must then pause. DTR will later go true (positive voltage) or a DC1 (Xmit on) will be transmitted when space becomes available and host transmission may resume. DTR is equivalent to most operating systems’ hardware protocol. Under the DTR and XON/XOF protocols ENQ will still generate the normal status response but it is not necessary to transmit ENQs in order to cause command execution.
3.13.4 Dual Port Option The Dual Port option allows for simultaneous connection to two hosts with each one alternately enabled using either the DTR or XON/XOF protocols. A port is enabled for 0.25 seconds or, if data is received, until no document is present and the buffer is empty. If configuration 05 is selected under 94 FUNCT, the display will show which port received data. 3.13.5 Parallel Interface Option A PC type parallel interface is optionally available.
4.0 THEORY OF OPERATION 4.1 OVERVIEW The DP6 & DP7 Document Printers handle and print a large variety of documents. The mechanism consists of a printhead, a printhead drive assembly and a document drive assembly. The electronics consist of an AC PCB (printed circuit board), a power transformer, a Main PCB, two sensor assemblies and a keypad/display assembly. 4.1.1 Printhead Drive Assembly The printhead drive assembly positions the printhead as it prints each line of characters.
semiregulated +/-12VDC and switching regulated +5VDC on the main PCB. The unregulated +30 to 40VDC drives the printhead and stepper motors. The DP6 also develops unregulated -30 to -40VDC to drive the printhead. The control electronics are based on a 6809 microprocessor, a 64 Kbyte EPROM, an 8K (DP6) or 32K (DP7) byte RAM, a 6522 I/O & timer device and an 8251 serial I/O communication device.
In the DP6 the 64 KByte EPROM U22 is selected by U25 pin 10 whenever either A14 or A15 is high, allowing 48 Kbytes of addressable EPROM. (In the DP7 the 64 or 128 KByte EPROM U24 is selected by U13 pin 19 whenever either A15 is high or any bank select BNK1 to 3 is low, allowing 64 or 88 Kbytes of addressable EPROM.) The EPROM contains the dot patterns for all printable characters and all programs that the 6809 executes to control the printer.

Motor rotation occurs by sequentially changing the phase and current signals to the two motor coils. Motor speed is controlled by how rapidly the signals are changed. Following is a state table where each state change rotates the document motor rotor 1/400 of a revolution (1/120" of document motion) and there are 8 distinct states before the pattern repeats. Direction of motor rotation can be reversed by moving up rather than down through the state table.

4.2.5 Keypad and Display (Refer to Schematics #72082 and #72080 or #72115) The keypad switches are arranged in a 4 by 4 X-Y grid. Address lines A0 to A3 drive the grid rows through 74LS367 buffer U10 (U12 in the DP7) and the grid columns are read onto the 6809 data bus through 74LS245 transceiver U19 (U22). The display is a 2 line by 16 character liquid crystal display (LCD) with integral electronics. All data transfers between the 6809 and the display are buffered through transceiver U19 (U22).

5.6 TROUBLESHOOTING 5.6.1 Basic Troubleshooting Procedure This procedure exercises everything in the printer except the interface to the host system. If any step is not successfully executed, refer to the corresponding troubleshooting section. 1. Turn on printer power. A) If nothing appears on the display, see 5.6.2. B) If < > BAD is displayed, replace the indicated component on the main PCB or the complete main PCB. C) If CARRIAGE FAULT is displayed, see 5.6.6. 2. Press 12345678 and then CLEAR.
5.6.4 Defective Sensor All sensors transmit and receive infrared light. The front (F) and back (B) document sensors are slot sensors that activate when the slot is blocked by a document. The back (B) and skew (S) sensors used in automatic alignment printers are reflective sensors that activate when an inserted document reflects light back on the sensor. The cover (C) and left home (L) sensors are toggled by metal flags that enters the sensor slots.
For any of the five (document, carriage left home and cover open) slotted optical sensors: 1. Check that the slot is free of debris and paper dust. In the case of the document sensors, check that it is aligned with the holes in the chutes. 2. Check that sensor connector is firmly seated on J5 of the main PCB. 3. Remove the sensor connector cover and check that the respective sensor wires are seated in their individual connector slots. 4. Replace the sensor (see 5.5.6 or 5.5.
5.6.8 Print Quality Symptom Printing ½ characters or a row of dots is missing, usually bottoms of lower case g, j, y, etc. Printer is printing streaks over printed lines. Documents jamming under the printhead. First few characters printed are partially formed. Large gaps in printing or sporadic light print occurs. Every other line of print is light or unreadable. Printing not dark enough on multiple part forms or receipts. Condition DP6 ribbon shield installed backward.
5.6.9 Missing Dots If a single row of dots is missing: 1. Refer to the printwire pinouts in the upper right corner of the main PCB schematics. Pin 1 prints the uppermost dots of uppercase characters, pin 8 (DP6) or pins 17 through 22 (prints lower case descenders (g,j,p,q and y) and pin 9 (DP6) or pin 24(DP7) prints underscores. Disconnect the flex cable from the main PCB and measure the resistance of the bad printwire through the cable. It should be approximately 16 ohms (DP6) or 8 ohms (DP7).
