For details of the adjustment items, refer to the detailed procedures and sketches of the adjustment items. Table 3-1. Adjustment Items Function Item Purpose Method Outline Tool Used Media Main Adjustment items 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 Adjustment fixed value.Exclusive servicing 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. Exclusive servicing program Non-target 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 servicing programNon-target 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. Exclusive servicing program Photo Quality Ink Jet Paper (A4) Bi-D Adjustment This adjustment is made to correct the print timing in the go and return paths in bi-directional printing.Select this function in the exclusive servicing program and print the adjustment patterns to check the displacement amounts of the patterns. Select/enter the pattern number that has the smallest displacement amount in the program. Print the exclusive patterns again and adjust the displacement amount. The correction value is saved into the EEPROM.Exclusive servicing programPlain paper (A4) 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. Exclusive servicing program Photo Paper / Glossy Photo Paper (A4)
