    Market Setting At the time of Main Board replacement, this adjustment is made 
    to write the board common information on a destination basis.Select and execute this function in the exclusive servicing program to 
    save the following data into the EEPROM.
    Market ID, CSIC Printer ID, D4 Setting (USB, Parallel), First Dot

    programNon-targetUSB ID Input
    This adjustment is made to allow the PC to recognize the 
    connected printers individually when multiple printers of the 
    same model are connected and used with the PC via a USB hub.
    Select this function in the exclusive servicing program and enter the 
    serial numbers of the printers. The correction value is saved to the 
    specific EEPROM address on the Main Board.

    Head ID Input At the time of Print Head replacement, this adjustment is made to 
    correct head manufacturing variations and eliminate the 
    individual differences of print quality.Enter the ID of the Head QR code label applied to the Print Head into 
    the exclusive servicing program to save it to the EEPROM on the Main 
    Board. (Supplement: Read the QR code label from left to right on the 
    top row and from top to bottom in due order.)Exclusive

    Head Angular 
    Adjustment
    This adjustment is made to correct the error in the Print Head 
    mounting position (angle of the Print Head to the paper surface) 
    to keep the nozzle intervals uniform in the CR main scanning 
    direction.
    Select this function in the exclusive servicing program and print the 
    adjustment pattern. Check the displacement amount of the pattern and 
    adjust it. Print the exclusive pattern again and adjust the displacement 
    amount.

    PW Sensor 
    Adjustment
    This adjustment is made to correct the mounting position of the 
    PW Sensor on a software basis to minimize the paper detection 
    error caused by the variations of the mounting position.
    Select this function in the exclusive servicing program and print the 
    adjustment patterns. Select the pattern number 5mm away from each 
    edge, and enter that number in the program. The correction value is 
    saved to the specific EEPROM address on the Main Board.

    Deviation 
    Correction
    When the Main Board, CR Motor or PSB/PSE Board is replaced 
    individually, this adjustment is made to write the maximum 
    offset to prevent the occurrence of damage to the motor at the 
    time of CR Motor heat generation.
    However, when the CR Guide Shaft is replaced together with the 
    above part, this adjustment is made to measure the manufacturing 
    variations of the CR Motor and PSB/PSE Board, utilize the motor 
    capability to the maximum for motor heat generation control, and 
    prevent the motor from being damaged by CR Motor heat 
    generation.
    Select and execute this function in the exclusive servicing program to 
    save the offset into the EEPROM.

    Protection Counter This function is used after repair to read the Waste Ink Counter, 
    and if the value is close to the predetermined near-end value or 
    end value, to recommend Pad replacement to the user in order to 
    prevent the repaired printer from being returned again for repair 
    in a short time. The reset function is used to reset the Waste Ink 
    Counter from the exclusive program after Waste Ink Pad 
    replacement.Select this function in the exclusive servicing program, read/display the 
    current data from the specific EEPROM address on the Main Board, 
    and check whether the current counter value is close to the upper limit 
    or not.
    For the reset function, select this function in the exclusive servicing 
    program after Waste Ink Pad replacement, and reset the corresponding 
    data at the specific address in the EEPROM on the Main Board.Exclusive

    This function is used to read the above necessary information 
    from the EEPROM of the faulty Main Board using the D4 
    function to reduce the auxiliary adjustment items at the time of 
    Board replacement.
    Select this function in the exclusive servicing program, and read the 
    data from the faulty board. After that, replace the Main Board and then 
    write the read data to a new board.
