■ After Replacing the Reader Upper Cover Unit
1. Enter the X, Y, and Z values indicated under the barcode on the Copyboard Glass in
• COPIER > ADJUST > CCD > W-PLT-X (White level data (X) entry of white plate) ,
• COPIER > ADJUST > CCD > W-PLT-Y (White level data (Y) entry of white plate) , and
• COPIER > ADJUST > CCD > W-PLT-Z (White level data (Z) entry of white plate) ,
and then write the entered values (the the X, Y, and Z values shown under the barcode on the Copyboard Glass) on the
service label.
NOTE:
The value of W-PLT-X: The first four digits of the value on the label
The value of W-PLT-Y: The four digits in the middle of the value on the label
The value of W-PLT-Z: The last four digits of the value on the label
2. AGC adjustment
1. Entering a provisional value
Change the foregoing values to "1,000".
• COPIER > ADJUST > CCD > LED-BW-R (Adjustment of LED light-up time (R) at B&W reading)
• COPIER > ADJUST > CCD > LED-BW-G (Adjustment of LED light-up time (G) at B&W reading)
• COPIER > ADJUST > CCD > LED-BW-B (Adjustment of LED light-up time (B) at B&W reading)
Change the foregoing values to "1,200"
• COPIER > ADJUST > CCD > LED-CL-R (Adjustment of LED light-up time (R) at color reading)
• COPIER > ADJUST > CCD > LED-CL-G (Adjustment of LED light-up time (G) at color reading)
• COPIER > ADJUST > CCD > LED-CL-B (Adjustment of LED light-up time (B) at color reading)
2. Adjust the white level in the following service mode.
• COPIER > FUNCTION > CCD > BW-AGC (CIS intensity adjustment in ADF (B&W))
• COPIER > FUNCTION > CCD > CL-AGC (CIS intensity adjustment in ADF (color))
3. If the operation was "successful", this procedure is completed. (There is no need to write the value on the service label.)
4. How to judge whether the operation was successful or failed
Whether the operation was successful or failed is not shown on the UI, so perform the following procedure to judge if
the operation was successful or failed.
B&W mode
• COPIER > ADJUST > CCD > LED-BW-R (Adjustment of LED light-up time (R) at B&W reading)
• COPIER > ADJUST > CCD > LED-BW-G (Adjustment of LED light-up time (G) at B&W reading)
• COPIER > ADJUST > CCD > LED-BW-B (Adjustment of LED light-up time (B) at B&W reading)
Check the foregoing values. If all of them remain "1,000", the operation result is judged to be "failed".
If the operation result is judged to be "failed", turn OFF and then ON the power, and execute COPIER > FUNCTION >
CCD > BW-AGC again.
Color mode
• COPIER > ADJUST > CCD > LED-CL-R (Adjustment of LED light-up time (R) at color reading)
• COPIER > ADJUST > CCD > LED-CL-G (Adjustment of LED light-up time (G) at color reading)
• COPIER > ADJUST > CCD > LED-CL-B (Adjustment of LED light-up time (B) at color reading)
Check the foregoing values. If all of them remain "1,200", the operation result is judged to be "failed".
If the operation result is judged to be "failed", turn OFF and then ON the power, and execute COPIER > FUNCTION >
CCD > CL-AGC again.
