1.3.17 Acquire white level data and set CIS scan area (function code: 55)
<Function>
This function is used to obtain the white level of the CIS unit, and store this data and the scan
area in the EEPROM of the main PCB.
<Operation Procedure>
(1) Press the [5] button twice in the initial state of maintenance mode. "Press START" is
displayed on the LCD.
(2) Press the [Start] button. "SCANNER AREA SET" is displayed on the LCD, and the white
level data is obtained.
(3) After several seconds, the compensation value for the white level data/scanning width is
stored in the EEPROM, and the machine returns to the initial state of maintenance
mode.
If any error is detected during this operation, "SCANNER ERROR" is displayed on the
LCD for single-side scanning models, and "SCANNER ERR ADF" or "SCANNER ERR
FB" for duplex scanning models.
When the [Stop/Exit] button is pressed, the machine returns to the initial state of
maintenance mode.
Note:
• In the event that the correct white level cannot be obtained when this function is
executed after the machine is released from Deep Sleep mode, install the latest
