Part 1: Safety and Precautions BJC-2000 1. SAFETY PRECAUTIONS 1.1 Moving Parts The moving parts of the printer are shown below. They include the carriage belt, idler roller, carriage, slow down gear, paper feed roller, pressure roller, eject roller, spurs, and pick-up roller. The first three parts above are driven by the carriage motor while the latter are driven by the paper feed motor. Avoid getting hair, clothing, jewelry, etc., caught in these moving parts.
Part 1: Safety and Precautions BJC-2000 1.2 Ink Stains 1.2.1 Ink path Do not touch the ink path while servicing as the ink can stain hands, work table, clothing, etc. The ink path consists of the BJ cartridge nozzles, head cap, head wiper, maintenance jet receiving section, and waste ink absorber. In the case of color BJ cartridges, the cartridge’s ink outlets and joint pipes are also part of the ink path. Caution! Although the ink is non-toxic, it contains organic solvents.
Part 1: Safety and Precautions BJC-2000 Black BJ Cartridge Color BJ Cartridge Color Ink Cartridge Ink Outlet Nozzles Black Ink Cartridge Joint Pipe Ink Outlet Nozzles Joint Pipe Figure 1-3 Ink Path of the BJ Cartridge 1.2.2 Ink mist The BJ cartridge ejects ink onto the paper. During prolonged or heavy-duty use of the printer, small amounts of ink mist which splatter off paper during printing can contaminate the inside of the front cover and platen.
Part 1: Safety and Precautions BJC-2000 1.3 BJ Cartridge Heat-Up Do not touch the BJ cartridge’s aluminum plate. The aluminum plate heats up during printing and becomes particularly hot during prolonged and continuous printing. It can overheat also if printing is continued even after the cartridge has run out of ink. Aluminum Plate Caution! High Temperature! Figure 1-5 BJ Cartridge Aluminum Plate NOTE REF. The printer has a protective mechanism when the BJ cartridge heats up.
Part 1: Safety and Precautions BJC-2000 2. MACHINE PRECAUTIONS 2.1 Precautions for Handling BJ Cartridges 2.1.1 Turning the printer ON/OFF The printer will automatically cap the cartridge heads one minute after printing operations are completed, to prevent the ink from leaking and drying out. When unplugging the power cord, wait at least one minute after completing an operation such as printing, feeding paper, cleaning the print head, etc.
Part 1: Safety and Precautions BJC-2000 2.2 Printer Precautions 2.2.1 Spur deformation prevention Do not deform the tips of the spurs. The spurs come into contact with the paper after printing. As the actual contact surface is small, any ink adhering to the spurs is minute and wiped off by the spur cleaners. Therefore any ink on the spurs is not enough to contaminate the paper as it passes.
Part 1: Safety and Precautions BJC-2000 3. PRECAUTIONS FOR SERVICE 3.1 EEPROM Data Precautions The printer keeps track of various settings, the total waste ink amount, and the total sheets printed with the black, color and photo BJ cartridges. This data is stored in the EEPROM on the logic board. Note the following precautions during servicing: 1) Before servicing Check the EEPROM data with a test print. The total sheets printed can give you an idea of how much the printer has been used.
Part 1: Safety and Precautions BJC-2000 3.2 Static Electricity Precautions The static charge accumulated from clothing, etc., can damage electrical components. To discharge any built-up static electricity, touch a metallic object that is grounded. Be sure to do this before disassembling the printer for servicing.

Part 2: Product Specifications BJC-2000 8) Input/ output signals: Compatible Mode STROBE [Input] This signal is used to read DATA1 to DATA8. The signal becomes valid after BUSY signal goes Low and the printer outputs an ACKNLG signal. The host computer does not send the next signal until it receives ACKNLG signal. It is normally High, after becoming Low, the printer receives data. When the signal remains Low, the printer does not operate until it goes High.
Part 2: Product Specifications BJC-2000 Nibble Mode Host Clk [Input] STROBE signal to read DATA 1 to DATA 8. Negotiation phase: Trigger signal to send the protocol confirmation to the printer. DATA 1-8 [Input] The printer receives data with the Host Clk signal. The state of each bit of this signal must be maintained for at least 0.5 µs from the rising edge of the Host Clk signal.
Part 2: Product Specifications BJC-2000 1284 Active [Input] This signal confirms that the printer is a 1284 compatible device when 1284 Active signal goes High and Host Busy signal goes Low. It goes Low with the termination phase. ECP Mode Host Clk [Input] This signal handshakes with the PeriphAck signal when data is transferred form the host computer to the printer. A Low Host Clk signal indicates that data has been output along the data buses (Data1-8).
Part 2: Product Specifications BJC-2000 Reverse Req [Input] This signal goes Low when the recovery process (data re-transmission) is taking place during data transmission from the host computer to the printer. In response to a Low Ack Reverse signal, Reverse Req signal goes High. When switching from the idle state of the forward data transmission phase to the reverse data transmission phase, i.e. data is transferred from the printer to the host computer, this signal goes Low.
Part 2: Product Specifications BJC-2000 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 confirms that the HostBusy signal is Low, it prepares 8-bit data, lowers the PtrClk signal and outputs the lower 4-bits along the control signal line. After the PtrClk signal is Low, the host computer receives the data and raises the HostBusy signal.
Part 2: Product Specifications BJC-2000 ECP mode In ECP mode, the printer transfers data at once in 8-bit units allowing faster data transmission and reception. This mode is suitable for large data transfers such as for scanners. After the computer responds to the Low Reverse Request signal, the AckReverse signal goes Low and the data bus direction switches from the forward data transmission phase (host computer to printer) to the reverse data transmission phase (printer to host computer).
