Error Name/Error Condition/Major Cause/Solution
Microcomputer communication error: 1st
Microcomputer communication error: 2st
Microcomputer communication error: 3st
Microcomputer communication error: 4st
Microcomputer communication error: 5st
The LDB (microcomputer) of the corresponding color is not working normally.
LDB defective (LD ASIC or microcomputer failure)
Cycle the main power switch off/on.
Replace the laser unit.
Error Name/Error Condition/Major Cause/Solution
The MUSIC pattern reading failed 4 times while the machine is turned ON.
When the color shift amount (sub scan registration, main scan registration, main
scan magnification ratio, main scan left/right magnification ratio, or skew) is equal
to or greater than the specified value, it is judged to be a failure.
Speed of ITB or drum rotation abnormal
LDB defective (LD ASIC failure)
Pattern density defection
Belt flawed or smudged
TM sensor smudged or defective
Skew Motor drive error
The MUSIC pattern is misaligned with respect to the TM/P sensor.
