1.4.16 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.
Note:
Always implement this operation when replacing the CCD unit, scanner unit or main PCB.
<Operating Procedure>
(1) Press the 5 button 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 button at this point, the machine will beep for one second and
return to the initial stage of the maintenance mode.
Enter the input data value of a 5-digit number based on the 4-digit number to be displayed
referring to the table below. (e.g., 4723 Æ 47247)
(3) The machine saves the magnification compensation setting value into the EEPROM, and
then it beeps for one second and returns to the initial stage of the maintenance mode.
