Symptom Possible Cause/Required Action
Trailing edge laser detection error: [K]
210
[C]
The laser synchronizing
detection signal for LDB [K]
of the trailing edge is not
detected for one second
after the LDB unit turned on
when detecting the main
scan magnification.
• Disconnected cable from the laser synchronizing
detection unit or defective connection
• Defective laser synchronizing detector
• Defective LDB
• Defective EGB
1. Check the connectors.
2. Replace the laser-synchronizing detector.
3. Replace the LDB.
4. Replace the EGB.
Trailing edge laser detection error: [Y]
211
[C]
The laser synchronizing
detection signal for LDB [Y]
of the trailing edge is not
detected for one second
after the LDB unit turned on
when detecting the main
scan magnification.
Same as SC 210
Trailing edge laser detection error: [M]
212
[C]
The laser synchronizing
detection signal for LDB [M]
of the trailing edge is not
detected for one second
after the LDB unit turned on
when detecting the main
scan magnification.
Same as SC 210
Trailing edge laser detection error: [C]
213
[C]
The laser synchronizing
detection signal for LDB [C]
of the trailing edge is not
detected for one second
after the LDB unit turned on
when detecting the main
scan magnification.
Same as SC 210
Laser Synchronizing Detection Error: LDB of the leading edge [K]
220
[D]
The laser synchronizing
detection signal for LDB [K]
of the leading edge is not
output for two seconds after
LDB unit turns on while the
polygon motor is rotating
normally.
• Disconnected cable from the laser synchronizing
detection unit or defective connection
• Defective laser synchronizing detector
• Defective LDB
• Defective EGB
1. Check the connectors.
2. Replace the laser-synchronizing detector.
