Description: 2nd laser synchronization error The LD2 synchronization signal cannot be detected by the main scan synchronization detector board even after 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: 327
Description: LD unit H.P. error 1 The LD unit H.P. sensor does not detect the on condition when the LD unit moves to its home position.
Causes: • H.P. sensor/harness defective • LD unit home position sensor defective • LD positioning motor harness defective • LD unit movement blocked because of incorrect connector routing
Code: 328
Description: LD unit H.P. error 2 The LD unit H.P. sensor does not detect an off condition when the LD unit moves from its home position.
Causes: • H.P. sensor/harness defective • LD positioning/harness motor defective • LD unit movement blocked because of incorrect connector routing
Code: 329
Description: LD unit beam pitch adjusted incorrectly The LD unit H.P. sensor does not detect the ON condition while changing the LD unit position to correct the LD position or to adjust the dpi.
Causes: • After initialization of the SP modes, SP2109-03 or SP2109-04 was not executed. • The harness is blocking the LD drive (PCB), preventing adjustment of the pitch
Code: 350
Description: ID sensor pattern test error One of the following ID sensor output voltages was detected twice consecutively when checking the ID sensor pattern. Vsp>=2.5 V Vsg<=2.5 V Vsp = 0 V
Causes: • ID sensor defective • ID sensor connector defective • Poor ID sensor connector connection • I/O board (IOB) defective • High voltage supply board defective • ID sensor dirty • Defect at ID sensor pattern writing area of the drum
Code: 351
Description: ID sensor Vsg test error When ID sensor checks the drum surface, VSG = 0, or PWM = 0
Causes: • ID sensor defective • ID sensor connector defective • Poor ID sensor connection • I/O board (IOB) defective • Scanning system defective • High voltage supply board defective • ID sensor dirty • Defect at the ID sensor pattern writing area of the drum
