8.4.12 Acquisition of White Level Data and CCD Scanner Area Setting (Function code 55)
Function
This function allows the machine to obtain white level data for the CCD scanner and save it
together with the CCD scanner area into the EEPROM on the main PCB.
Operating Procedure
(1) Press the [5] key twice in the initial stage of the maintenance mode.
The “SCANNER AREA SET” will appear on the LCD.
(2) When setting of the scanner area is completed, a 4-digit number will appear on the LCD.
(e.g., 4723)
* If you press the
[Stop/Exit] key at this point, the machine will return to the
maintenance initial stage of the maintenance mode.
Based on this 4-digit number and referring to the input data specified in the table, input
its corresponding 5-digit data value (input data). (e.g., 4723? 47247)
(3) Save the magnification compensation setting value in the EEPROM, and then return to
the initial stage of the maintenance mode.
