SC Level Symptom Possible Cause
LD unit H.P. error 1 327 B
The LD unit H.P. sensor does not
detect the on condition when the LD
unit moves to its home position.
•
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
LD unit H.P. error 2 328 B
The LD unit H.P. sensor does not
detect an off condition when the LD
unit moves from its home position.
•
H.P. sensor/harness defective
•
LD positioning/harness motor
defective
•
LD unit movement blocked
because of incorrect connector
routing
LD unit beam pitch adjusted
incorrectly 329 B
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.
•
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
