The automatic Gain control (AGC) for a specific channel from the CCD PWB Failed.
Possible fixes include:
#1 The Exposure lamp is too slow. (Scanner lamp)
Replace the lamp.
#2 Cleaning ALL the mirrors and the top of the silver strip above the mirrors on the carriage. ( Part of the carriage that holds the mirror on the left hand side when facing the machine.
#3 The IIT/IPS LVPS needs to be replaced.
Hope this helps.
