Description: No Laser Writing Signal (F-Gate) Error 1 Definition [B] The laser writing signal (F-gate) does not go to LOW for more than 15 seconds after the paper reaches the registration sensor.
Description: 1st Laser Synchronization Error Definition [B] The 1st laser synchronization signal cannot be detected by the main scan synchronization detector board even if the laser diodes are activated.
Causes: · Poor connection between the laser synchronization detector board and the LD unit. · Laser synchronization detector board out of position · Laser synchronization detector board defective · LD unit defective
Code: SC323
Description: LD Drive Current Over Definition [B] The LD drive board applies more than 110 mA to the LD.
Causes: · LD unit defective (not enough power, due to aging) · Poor connection between the LD unit and the BICU board · BICU defective
Code: SC326
Description: 2nd Laser Synchronization Error Definition [B] The 2nd laser synchronization signal cannot be detected by the main scan synchronization detector board even if the laser diodes are activated.
Causes: · Poor connection between the laser synchronization detector board and the LD unit. · Laser synchronization detector board out of position · Laser synchronization detector board defective · LD unit defective
Code: SC327
Description: LD Unit Home Position Error 1 Definition [B] The LD unit home position sensor does not detect an on condition when the LD unit moves to its home position.
Causes: · LD unit home position sensor defective · LD positioning motor defective · LD unit movement blocked because of incorrect connector routing
Code: SC328
Description: LD Unit Home Position Error 2 Definition [B] The LD unit home position sensor does not detect an off condition when the LD unit moves from its home position.
Causes: · LD unit home position sensor defective · LD positioning motor defective · LD unit movement blocked because of incorrect connector routing
