Message
Detail In shading correction, the CCD white reading level is abnormal (with the scanner lamp OFF).
Section Scanner (reading) / ICU SCAN PWB
Operation mode Warm-up / Initialize
Note
Case 1 Trouble
position/Cause
Improper CCD white level gain
Too great CCD white level gain
Remedy (Check)
1) Use SIM 63-1 to check the values of ADJUST ODD GAIN and ADJUST EVEN GAIN of each color
of R/G/B. (There are six values in total.) (AR-C150)
2) Add 25 to each value of GAIN ODD and GAIN EVEN of R/G/B checked in procedure 1) and make
notes of the total values. (AR-C150)
3) Enter the SIM 46-6 mode, and replace each value of GAIN ODD and GAIN EVEN of R/G/B with
the total values calculated in procedure 2). (Input the new value.) (AR-C150)
4) Cancel the simulation.
5) Turn OFF/ON the power, and shading operation will be performed.
(Repair) Power OFF-ON
(After work)
Note This trouble occasionally happens when the CCD unit (with the lens) is replaced.
Case 2 Trouble
position/cause
Bad connection of the flat cable between the CCD unit and the ICU SCAN PWB.

Discrepancy of the model code (The AR-LC2, instead of the AR-LC2N, is erroneously installed to the
AR-C160/C270.).
Remedy (Check) Check that the AR-LC2N or the AR-LC2 is installed.
(Repair) Install the AR-LC2N or remodel the AR-LC2 into the AR-LC2N. (Replace the AR-LC2 ROM
with the AR-LC2N ROM, and replace the 1A fuse on the ADU control PWB with the 1.25A fuse.)
(After-work)
Note

10 – 10A
