2. Upon completion of parameter initialization, the machine returns to the initial stage of the maintenance
mode.

Printout of Scanning Compensation Data (Function code 05)
Function
The machine prints out the white and black level data for scanning compensation.
Operating Procedure
Do not start this function merely after powering on the equipment but start it after carrying out a sequence
of scanning operation. Unless the equipment has carried out any scanning operation, this function cannot
print out correct scanning compensation data. This is because at the start of scanning operation, the
equipment initializes white and black level data and takes in the scanning compensation reference data.
1. Press the "0" and "5" keys in this order in the initial stage of the maintenance mode.
The "WHITE LEVEL 1" will appear on the LCD.
2. The equipment prints out the scanning compensation data list containing the following:
a) Bright output adjustment value 1Byte
b) Illuminant adjustment value 1Byte
c) Black level MIN data 1Byte
d) Black level MAX data 1Byte
e) White level MIN data 1Byte
f) White level MAX data 1Byte
g) Background color compensated data 1Byte
h) Black level data 1664Byte
i) White level data 1664Byte
3. Upon completion of recording of the compensation data list, the equipment returns to the initial stage
of the maintenance mode.
• If any data is abnormal, its code will be printed in inline style, as shown on the next page.
