Part 1: Safety and Precautions BJC-50 1. PERSONAL SAFETY PRECAUTIONS 1.1 Moving Sections of the Printer Be careful not to let your hair, clothes, accessories, etc., become caught in any of the moving sections of the printer. The moving sections of the printer are the carriage belt, carriage ribbon cable and carriage, which are driven by the carriage motor, and the paper feed gear and roller, pinch roller, eject roller and spurs which are driven by the paper feed motor.
Part 1: Safety and Precautions BJC-50 1.2 Ink Stains 1.2.1 Ink path Be careful not to touch the ink path of the printer and get stains on the work table, hands, clothes, etc., during repair. The ink path is the nozzle section of the BJ cartridge, the head cap, the head wiper, the maintenance jet receiving section and the waste ink absorber. The ink inlets of the ink cartridge and the joint pipes of the print head body are also part of the ink path, so take the same precautions.
Part 1: Safety and Precautions BJC-50 1.2.2 Ink mist The BJ cartridge ejects the ink onto the paper. After the printer has been used for a long time or under heavy duty use, a small amount of ink mist bouncing off the paper during printing may soil the platen section and the purge section. This soiling may soil the paper or the hands or clothes of service personnel, so wipe it off with a soft cloth or the like dampened with water.
Part 1: Safety and Precautions BJC-50 1.3 BJ Cartridge Aluminum Plate Do not touch the aluminum plate of the BJ cartridge. The aluminum plate heats up during printing and becomes particularly hot during continuous high duty printing. It also heats up if printing is operated after the ink in the cartridge has run out. Danger ! High Temperature! Figure 1-4 BJ Cartridge Aluminum Plate This printer has the following functions to protect against the above temperature rise.
Part 1: Safety and Precautions BJC-50 2. MACHINE PRECAUTIONS 2.1 BJ Cartridge 2.1.1 BJ cartridge handling To prevent clogging at the nozzles due to foreign matters, never touch the nozzle section of the BJ cartridge or wipe it off with tissue paper or the like. For the BJ cartridge, take the same care with the ink filter of the print head body to prevent poor ink suction due to foreign matters.
Part 1: Safety and Precautions BJC-50 2.1.2 Automatically capping When the power is switched off with the POWER button, the printer automatically caps the nozzle section of the BJ cartridge to protect itself and prevent ink leakage. If you unplug the DC plug by mistake and cut off the power supply to the printer, plug the DC plug back in, start up the printer normally, then switch off the power with the POWER button.
Part 1: Safety and Precautions BJC-50 2.2 Ink Cartridge 2.2.1 Ink cartridge handling To prevent poor ink suction due to foreign matters on the ink filter of the print head body, never touch the ink filter of the ink cartridge. When you remove the cap from an ink cartridge, install the ink cartridge on the print head body immediately to prevent clogging at the nozzles due to ink drying or foreign matters. Do not remove the ink cartridge unless you are replacing it.
Part 1: Safety and Precautions BJC-50 2.3 Lithium Ion Battery Handling 2.3.1 Initial precautions The enclosed lithium ion battery must be installed in the printer and charged prior to its use. To ensure best performance, the lithium ion battery is only charged to 40% of its full capacity at the time of shipping. The battery must be fully charged once it is unpacked. After connecting the AC adapter and turning on the printer, the installed battery automatically begins charging.
Part 1: Safety and Precautions BJC-50 2.4 Printer Handling 2.4.1 Precautions to prevent damage from static electricity The electrical charge accumulated on a person when clothes rub can damage electric elements or change their electrical characteristics. Never touch the contact section of the carriage ribbon cable.
Part 1: Safety and Precautions BJC-50 2.4.2 Ink leakage precautions Do not carry, pack or store the printer without a BJ cartridge installed. The ink within the cap section will flow back and soil the inside of the printer. The nozzle section of the BJ cartridge is capped automatically when the power is switched off with the POWER button. When the power is turned off, the carriage is locked so that it does not move from the capping position.
Part 1: Safety and Precautions BJC-50 3. PRECAUTION FOR SERVICE 3.1 Precautions Concerning the Memory Data This printer counts the total waste ink amount for the black BJ cartridge and the color BJ cartridge and stores these data in the EEPROM on the control board. Observe the following precautions during servicing. 1) Checking EEPROM data The number of sheets printed is counted and stored in the EEPROM to show the printer operating status. This data can be printed by test print 3 (Ripple pattern print).
Part 1: Safety and Precautions BJC-50 3.2 Precautions to Prevent Damage from Static Electricity The electrical charge accumulated on a person when clothes rub can damage electric elements or change their electrical characteristics. In order to prevent static electricity, make sure to touch some metallic part that is grounded to release the static electricity accumulated on your body before disassembling the printer for service.
Part 1: Safety and Precautions BJC-50 3.3 Precautions for Disassembly/Assembly The printer is made by combining many plastic parts. When disassembling the printer, be careful not to brake or bend plastic hooks. Take special care not to rip or bend the flexible cables when removing and reinserting them on the control board as they are very thin and frail. Also to prevent misconnection, make sure the cable is fully inserted in the connector.
Part 1: Safety and Precautions BJC-50 When replacing the IrDA unit, be careful not to touch the light emitting and receiving parts. (Touching these parts may offset the optical axis or soil the lens and possibly inhibit infrared communication.) IrDA unit Figure 1-12 IrDA Unit 3.4 Built-in Self-diagnostic Functions The printer has built-in self-diagnostic functions to judge hardware defects.

Note) Lithium ion battery initialization begins here.
Part 4: Technical Reference BJC-50 1.2.2 Scanner mode When powered on, the printer starts up in the printer mode regardless of the printer head type. Once the printer is on, it stands by to receive a data or a command. When the printer recognizes the scanner activation command, the printer starts operating in the scanner mode. After the printer recognizes the scanner head and performs the POWER ON operation, the printer starts to preheat the scanner head.
Part 4: Technical Reference BJC-50 1.3 Print Signal Flow The print signal flow from when the printer receives the print data to when printing is executed is described below. a) The print data (including the control signals) output by the computer is received by the ASIC through the interface, which is controlled by the ASIC on the logic board. Through the dedicated bus between the printer controller and DRAM, print data is stored in the DRAM's receive buffer area.
Part 4: Technical Reference BJC-50 1.4 Print Drive The printer outputs control signals from the ASIC's printer controller to the BJ head to eject ink from the BJ head for printing. The control signals consist of the print control signal for ejecting ink from the head's nozzles and the temperature control signal for adjusting the head's temperature so that the amount of ink ejected is uniform.
Part 4: Technical Reference BJC-50 The HEAT ENABLE signals control the ejection of small and large ink droplets as follows: For each color, (Y, M and C), HENB B and A signals drive the front and back nozzle heaters respectively. For black, HENB C and D signals drive the front and back nozzle heaters respectively. The HEAT ENABLE signal consists of the pre-pulse and the main pulse that optimize ink ejection by constantly monitoring the head rank, the printer inner temperature and head temperature.
Part 4: Technical Reference BJC-50 1.5 Scanner Drive The scanner cartridge is recognized by the scanner cartridge contacts and TOP.S, C.CHA and C.CHK signals. These three signals are equivalent to the TOP, DIODE A and DIODE K signals of the BJ cartridge. Color distinction is performed by ID 0 and ID 1 as in the BJ cartridge. The three signals, CMD 0 (REN), CMD 1 (RWR) and CMD 3 (RDT) are used to set data in the scanner resistor.
Part 4: Technical Reference BJC-50 1.
Part 4: Technical Reference BJC-50 2. FIRMWARE 2.1 Interface The printer supports a parallel interface and IrDA interface. The parallel interface is compatible with the bidirectional Centronics interface-standard (IEEE 1284). Compatible mode is the same as the Centronics interface-standard protocol. IrDA is an infrared data communication interface that is compatible with IrDA (1.0). The interface data transfer timing for each of the parallel interface mode is described below. 2.1.
Part 4: Technical Reference BJC-50 2.1.2 Nibble mode In nibble mode, the printer transfers data twice to the host computer in 4-bit units. The data is transferred with the PtrClk signal and HostBusy signal handshakes. After the printer negotiates with the host computer and enters the nibble mode, the printer confirms that the HostBusy signal is low, outputs a PtrClk signal with a nibble setting on the lower bits and lowers the PtrClk signal.
Part 4: Technical Reference BJC-50 2.1.3 ECP mode In ECP mode, the PeriphAck signal and the HostClk signal handshake to communicate. After the host computer negotiates with the printer, the printer raises the PeriphClk signal and the host computer lowers the HostAck signals. At this point the host computer sets the data on the bus and lowers the HostClk signal to transmit the data. When the printer is ready to receive data, it raises the PeriphAck signal.
Part 4: Technical Reference BJC-50 2.1.4 IrDA IrDA is an IrDA (1.0) conforming infrared serial communicating device that is built-in on the back side of the printer. Input and output of infrared light is conducted through this device. For wireless infrared one-to-one communication, the computer's IrDA and the printer's IrDA must be facing each other. The infrared light emitted from the IrDA travel sideways and lengthwise as sown in Figure 4-9. The forward direction is the light axis.

Part 4: Technical Reference BJC-50 b) IrDA standard To connect data transmission devices using infrared communication, the protocols physical and transport layers have been standardized. 1) Physical Layer (IrDA-SIR) 2) Dataring Layer (IrLAP and IrLMP) 3) Transport Layer (IrTP) The Printer does not have a IrTP in the transport layer. In the physical layer standards (IrDA-SIR), the infrared signal are established. The physical layer of the IrDA uses RZ signals in the base band format.
Part 4: Technical Reference BJC-50 2.2 720 dpi Printing/Smoothing Feature 2.2.1 Canon extension mode In Canon extension mode, the printer driver creates 720 dpi data for the horizontal axis and sends it to the printer, allowing the printer to archive high-quality printing. With a black BJ cartridge installed, the printer driver smoothes the printed character's edges to 720 dpi along the horizontal axis.
Part 4: Technical Reference BJC-50 2.3 Printing Modes 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 to1/720 inch.
Part 4: Technical Reference BJC-50 2.4 Optimum Printing Direction Control To prevent vertical misalignment of the printed characters, etc., when print data is printed continuously in the direction of the paper feeding direction, printing is executed with the carriage moving from only one direction.
Part 4: Technical Reference BJC-50 2.6 Lithium Ion Battery Recharging 2.6.1 Switching to recharge mode The lithium ion battery must always be installed in the printer as the recharging circuit for the battery is inside the printer. When the printer is in stand-by mode or soft power OFF, the battery begins to recharge. Recharging is stopped when printing starts as the power supply from the Universal adapter is limited.

Part 4: Technical Reference BJC-50 4.3.
Part 4: Technical Reference BJC-50 a) Pre-recharging Circuit When the lithium ion battery voltage is low, the pre-recharging circuit and small amounts of electrical current are used to raise the voltage. Once the voltage level rises to the normal level, this circuit is stopped. b) Constant Current/Voltage Recharging Circuit Constant current is maintained until the lithium ion battery voltage reaches 12.3 V. Once it reaches 12.3 V, the control mode switches to constant voltage to maintain a stable 12.
Part 4: Technical Reference BJC-50 c) Battery temperature detection The thermistor inside the lithium ion battery pack measures the internal battery temperature and detects whether the battery is installed or not. This thermistor is connected between the T terminal and negative terminal of the battery pack. ASIC uses the A/D value of the thermistor's output voltage, THBAT, to determine whether the battery temperature is normal. If it is, the recharging will begin.
Part 4: Technical Reference BJC-50 5. DETECTION FUNCTION The printer uses HP sensor, paper end sensor, delivery sensor, inside temperature sensor, and head temperature sensor. Also, the capacity of the waste ink absorber is stored in the EEPROM. When the absorber is about to become full a warning is given and when full an error will occur. The printer detects the level of the ink remaining in the ink cartridge by counting the number of dots ejected, and indicates when the ink runs out.
Part 4: Technical Reference BJC-50 5.6 Waste Ink Level Detection Ink ejected by the maintenance jet or collected from purging during recovery is absorbed by the waste ink absorber. The total amount of ink consumed is calculated by adding the number of dots ejected and the recovery counts.
