When a RAM error or ROM error occurs, the exact error may not be
displayed correctly. When replacing the logic board, execute the
"EEPROM all clear" function in Service mode, then calibrate the auto
alignment sensor. In addition, check the amount of waste ink absorbed by
the waste ink absorber in the bottom case unit. If necessary, also replace
the waste ink absorber or set the waste ink counter value in Service mode.
(See Part 5, "4.3 Logic Board and Waste Ink Absorber Replacement Cautions.")
During initialization, the contents in the ROM cannot
be read.
