Chapter 1: General Description Maintaining BJ Cartridges One of the most important elements in maintaining your C3000’s excellent print quality is to clean the BJ cartridge’s print head regularly, and to replace the BJ ink cartridges and tanks promptly when needed. Cleaning and Testing the BJ Cartridge Print Head The print head in the BJ print cartridge contains nozzles through which ink is propelled onto the paper.
Part 1: Facsimile 5. Check whether cleaning corrected the problem by printing or copying a document. 6. If necessary, repeat this procedure up to four more times (giving five cleanings in all). If the problem persists after this, install a new BJ cartridge. See “Replacing the BJ Cartridge”. When to Replace the BJ Cartridge How frequently you need to replace your C3000’s BJ cartridge or one of its ink tanks depends on how you use your C3000.
Chapter 1: General Description In addition: START/COPY ❏ If you are using the BC-21 Color BJ cartridge and your output is blank, one of the ink tanks is probably empty and needs to be replaced. Print the NOZZLE CHECK test pattern to check whether the BJ cartridge needs replacing or not. ❏ If the message CHANGE CARTRIDGE appears in the LCD display, the BJ cartridge may have run out of ink. This message also appears if the C3000 has to store a fax in its memory because the cartridge is out of ink.
Part 1: Facsimile Storing BJ Cartridges Once a BJ cartridge is unwrapped, its print head must be kept from drying out, or it can clog and fail to work properly. A cartridge installed in the C3000 is protected from drying out by automatically moving to the home position at the right side of the unit and capping itself. If you remove a partially used BJ cartridge from the C3000, store it in the SB-21 BJ cartridge container that came with your unit. 1.
Chapter 1: General Description b) Unpacking the BJ cartridge Do not open the BJ cartridge packaging unless you are ready to install the new BJ cartridge. Before installing the BJ cartridge, gently remove the orange head cap and the orange protective tape from the nozzles.

If the paper size setting does not match the size of the paper installed.
Chapter 1: General Description (C) Replacing the PCNT board The PCNT board stores the absorption amount of waste ink absorber and vertical alignment data. Therefore, when replacing the PCNT board, print out the absorption amount data and then enter this data into the new PCNT board, and then adjust vertical alignment. 5.3.
Part 1: Facsimile 5.4 Data-related precautions The memory IC on the circuit board stores the user’s registration data and values for various counters, etc., required for servicing. Although this data is normally retained in memory, it can be deleted by mistake. When handling this data during servicing, note the following precautions.
Chapter 1: General Description 5.4.1 Data in the image storage memory (DRAM) DRAM stores image data which was read other than by a direct transmission. It also acts as a buffer memory to store the image data received. If power is turned off, the memory clear list is printed automatically the next time the power is turned on. The user is thereby notified of the images that were erased from memory.
Part 1: Facsimile 5.4.2 Data in the control processing memory (SRAM) SRAM is backed up by a lithium battery. It can retain the stored data for 5 years after the power is turned off.
Chapter 1: General Description 5.4.3 Data in the EEPROM The EEPROM stores the absorption amounts of the waste ink absorber and vertical alignment data. The non-volatile EEPROM does not require any electrical power to retain the data it contains. Calculation of the total waste ink amount of the waste ink absorber starts immediately after the printer is used.

Lifting Plate This plate moves upwards by the force of the springs and the release cam mechanism, lifting the paper stack until it touches the Pickup Roller. After separation, it moves back down to its original position. 3. Pickup roller ➔ See Page 2-10. The pickup roller has a semi circular roller.
Part 1: Facsimile NOTE Paper feed motor drive switching Power from the paper feed motor is switched for separation and feed of the paper, and nozzle cleaning mechanisms by the direction of paper feed motor rotation, the slide lock pin on the purge unit and swing gear. When the carriage moves in front of the purge unit, the carriage pushes the control pin, and releases the swing gear driven by the paper feed motor.
Chapter 2: Technical Reference NOTE Paper Separation Mechanism (Automatic feed / Manual feed) This model has no paper selection lever on the automatic sheet feeder. If the paper meets specifications, it can be fed without selecting operation the paper type. The paper is loaded in the auto sheet feeder such that a corner of it is caught by the paper separator. When printing starts, the pick-up roller starts to rotate through the drive of the paper feed motor.
Part 1: Facsimile NOTE Paper feed error detection There are three types of paper feed error which may occur: a) No paper error Occurs when the Paper Edge Sensor does not detect the paper’s leading edge the start of the paper picked up operation is executed, it is executed again. If the paper is still not sensed , it is assessed as a No paper error. b) Eject delay jam Occurs when the Paper Edge Sensor does not detect the paper’s trailing edge after the page has been printed, or after 22 inches (558.
Chapter 2: Technical Reference 4. PRINTER SECTION The printer section mechanism in this model is taken from the BJC-4200 BJ printer. Major changes are as follows. • Cartridge installation is not performed from the front, but from above. • The spur attachment location has been changed. • An ink detection sensor has been added.
Part 1: Facsimile Names and functions of parts 1. Home Position Sensor (HPS) ➔ See Page 2-15. This sensor detects the home position edge and carriage position. Also, at the capping position, the on/off of purge sensor flag during the pump operation is detected. 2. Carriage Motor This is a stepping/pulse type motor, which is controlled with pulse width modulation. It moves the carriage by belt drive. 3. BJ Cartridge ➔ See Page 2-20. 4.
Chapter 2: Technical Reference For details on BJ cartridge holding, carriage drive and pump operation state detection, see the FACSIMILE BASIC•INTER SUPPLEMENT 2 (supplied separately).
Part 1: Facsimile NOTE BJ head protection In order to always maintain good print quality, this model performs cleaning of the BJ head at appropriate times. There are three types of cleaning operations: pump suction, wiping, and maintenance jet. Also, the print head is capped after printing, to preserve the head. • Cleaning operation (pump suction) Cleaning operation is performed using the cap and pump of the purge unit.
Chapter 2: Technical Reference NOTE Print Shift Correction Print gaps can occur when doing bidirectional printing, due to changes in the weight of the BJ cartridge and mechanical errors. This gap is corrected by adjusting the carriage drive motor load and the carriage position, which is determined logically from the number of stepping pulses. Gap detection is performed before the start of printing, during the home position detection operation.
Part 1: Facsimile NOTE Ink empty detection Ink empty detection during fax operation is performed by firing black ink between the light source and receptor of the ink sensor, located on the left side of the printer. This function does not work with the BC-22, only with BC-21 or BC-20. When ink passes between the source and the receptor, as shown in Figure 2-12, the sensor output will be a pulse waveform. The presence of ink may be determined from the pulse generation time.
Chapter 2: Technical Reference NOTE Waste Ink Absorbers This model has a single ink absorber which absorbs waste ink as follows. • Suction waste ink Waste ink sucked from the cap • Maintenance jet waste ink Waste ink from the test firing used to adjust the nozzle condition • Ink detection waste ink Waste ink fired to detect the presence of remaining ink during fax receipt The amount of ink absorbed is counted as a total of all of these.

Part 2: Printer BUSY When the printer makes BUSY high, it cannot receive data. The BUSY line goes high in response to a -STROBE pulse. This line remains high until the data are read. BUSY is also high under the following conditions: • The receive buffer is full of data. • The printer receives an -INIT signal. • A printer error condition, such as out-of-paper, occurs. P.E. (Paper End) The printer sets P. E. high when it is out of paper or when a paper jam occurs. P. E.
Chapter 1: General Description Timing chart The parallel interface transfers data in one direction only: from computer to printer. The data path is 8 bits wide. The printer and the computer synchronize data transfer with the interface signals, -STROBE, -ACKNLG, and BUSY. When the computer is ready to send a byte of data to the printer, it puts the byte of data on the data lines (DATA 1 through DATA 8). Then the computer sends a -STROBE pulse to the printer. The printer responds with a BUSY signal.

Chapter 2: Technical Reference 1. THEORY OF OPERATIONS 2.1 Outline In the facsimile mode, the printer part prints the received image from the facsimile circuit as described in Part 1. In the printer mode, the printer part prints the character and image data from the computer via the centronics type 8-bit parallel interface.
Part 2: Printer 2.2 Mechanical Overview For details on mechanical overview of printer mechanism, see Part 1: Facsimile, Chapter 2: Technical Reference.
Chapter 2: Technical Reference 2.3 Data Flow 1) Interface Character codes, control codes, and image data conforming to the printer's character table are sent to the interface from the computer. The data are received when the printer is in on-line standby, or when the carriage changes directions during printing. 2) Input buffer Data received from the interface are stored in the printer DRAM's built in input (reception) buffer.
Part 2: Printer 2.4 Printing The printer prints the fonts horizontally, and feeds the paper vertically. The printing design of the fonts are written into the font ROM*, and is usually made up of 360 dpi; 48 nozzles × 36 dots × 2 lines. Nozzles 49 to 60 and 113 to 124 are for spacing to next line, and for IBM block graphic character printing. Nozzles 61 to 64 and 125 to 128 are not used in printer mode**. The default character pitch in the horizontal direction is 10 cpi (characters per inch).
Chapter 2: Technical Reference 2.5 Circuit Overview 2.5.1 Printer circuit This printer circuit is the same as the circuit for the facsimile printer. This section explains the operations of the circuit in printer mode.
Part 2: Printer a) MPU (IC1) Printer controller (IC5) is controlled by the Control/CG ROM (IC3) program to control printer mode operations. b) Control/CG ROM (IC3) Besides the printer hardware control program and font image data, the following data are stored in the Control/CG ROM. • Emulation software This is the control program for the printer, which can emulate either IBM Proprinter X24E, or EPSON LQ-2550. • Font image data The 360 dpi character design data for each of the BJ cartridge nozzles.
Chapter 2: Technical Reference 2.6 720 dpi Printing/Smoothing Feature 2.6.1 Canon extension mode In the Canon extension mode, the printer driver creates 720 dpi data for the horizontal axis and sends it to the printer, resulting in high-quality printing. With a black BJ cartridge installed, the printer driver smoothies the printed character’s edges at 720 dpi along the horizontal axis. The 720 dpi data for the horizontal axis is sent to the printer and the edges are smoothed at a high resolution.
Part 2: Printer 2.7 Printing Modes 2.7.1 Printing mode Depending on the cartridge installed, the medium, the printing mode, the resolution, the print data, etc., the printer varies the carriage movement, bubble jet head driving frequency, etc., to attain high-quality printing without any bleeding or shifting in the printout. When the 720 dpi printing/smoothing feature is used, the carriage feed pitch is set to 1/720 inch.

Part 2: Printer 2.8 Optimum Printing Direction Control To prevent vertical misalignment of the printed characters, etc., when printing data is printed continuously in the direction of the paper feeding direction, printing is executed with the carriage moving from only one direction.
Chapter 2: Technical Reference 2.10 Bi-Centronics Interface The Bi-Centronics interface is supported to maintain upward compatibility with the conventional Centronics interface and implement bi-directional communication. MultiPASS C3000 supports three interface modes: Compatibility, Nibble and ECP modes which conform to IEEE-P1284 D2.00 Sep. 10, 1993. 2.10.
Part 2: Printer 2.10.2 Structure a) Centronics uni-directional interface (Compatibility mode) See Part 2: Printer, Chapter 1: 2.2 Interface Specifications on page 1-5. b) Bi-Centronics Interface (Nibble mode) In Nibble mode, the host computer sends data to the facsimile using the 8-bit data line as used for the Centronics interface. However, the facsimile transfers data to the host computer using the four status signal lines by dividing 8-bit data into 4 bits and sending them.
Chapter 2: Technical Reference b-2) Data transfer from the facsimile to the host computer in Nibble mode Data is transferred by the following steps. The host computer sets HostBusy to low to indicate that it is ready to receive data (①). The facsimile sets the low-order nibble of the byte (0 to 3 bits) to four lines: nDataAvail, Xflag, AckDataReq, and PtrBusy. (These lines are the reverse channel data lines.)(②). The facsimile sets PtrClk to low (③), and the host computer receives data (0 to 3 bits).
Part 2: Printer c) Bi-Centronics Interface (ECP mode) If the host computer supports ECP mode, your MultiPASS unit transfers data in ECP mode. If the host computer does not support ECP mode, your MultiPASS unit transfers data in Compatibility mode and Nibble mode. ECP mode must be set for some host computers. ECP stands for Extended Compatibility Port. Data can be transferred at high speed in ECP mode.
