SC 329 level B symtom 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.
Possible Cause
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.
fix the customer first then fix the machine... its simple and makes life more easy.
If the toner is dropping a lot on the LD board, then the board must be soldering out the laser diode, and clean the inside unit of the assembly. Clean all mirror inside the laser unit, perform the laser beam pitch adjustment.
