Description: Polygon motor error
The polygon motor does not reach its operating speed within 10 seconds after the polygon motor on signal, or the lock signal is not detected for more than a certain time during operation.
Causes: • Polygon motor • Polygon motor cable
Code: 220
Description: 1st laser synchronization error
The laser synchronization detector cannot detect the laser synchronization signal for more than 5 consecutive 100 ms intervals.
Causes: • Laser synchronization detector board out of position • Laser synchronization detector board or cable defective • Laser synchronization mirror out of position • LD unit defective • Engine board defective
Code: 221
Description: 2nd laser synchronization error
The 1st LD1 is already on, but the laser synchronization detector cannot detect the laser synchronization signal from the 2nd LD for more than 5 consecutive 100 ms intervals.
Causes: • Laser synchronization detector board out of position • LD unit defective • Engine board defective
Code: 230
Description: FGATE error
The FGATE signal cannot be detected for 1 second after the machine has sent a start trigger. The FGATE signal is still detected for 13 seconds after the machine has detected the FGATE signal.
Description: LD error
The machine detects LDB error a few times consecutively when LDB unit turns on after LDB initialization.
Causes: • Worn-out LD unit • Disconnected or broken harness of the LD unit • LD unit defective
Code: 300
Description: Charge roller current leak
60% or more of the PWM duty output is detected for 0.2 seconds when the charge bias is generated by the charge roller.
Causes: • Cartridge (charge roller) defective • High voltage supply board defective
