Description: LD unit home position error 1
The LD unit home position sensor does not detect an on condition when the LD unit moves to its home position.
Causes: • HP 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 home position error 2
The LD unit home position sensor does not detect an off condition when the LD unit moves from its home position.
Causes: • HP 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 HP sensor does not detect the ON condition while changing the LD unit position for correcting the LD position or changing the dpi.
Causes: • After initialization of the SP modes, SP2-109-3 or SP2-109-4 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. 1) Vsp >=2.5V 2) Vsg <= 2.5V 3) Vsp = 0V 4) Vsg = 0V
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 the ID sensor was checked, the ID sensor output voltage was 5.0V while the PWM signal input to the ID sensor was 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
Code: 352
Description: ID sensor, pattern edge detect error
The ID sensor pattern edge voltage is detected to be not 2.5V twice consecutively during an 800 ms interval.
Causes: • ID sensor defective • ID sensor connector defective • Poor ID sensor connector connection • I/O board (IOB) defective • High voltage supply board defective • Dirty ID sensor • Defect at the ID sensor pattern writing area of the drum
