Laser scanning unit (LSU) removal
Before performing this task, determine first whether your printer supports a galvo or polygon LSU.
• Check the serial number of the printer. The LSU is galvo if the sixth digit character assigned is in the 0–9
or B–N range (example: 4514 20HH 007CR). It is polygon if the sixth digit character assigned is in the P–
Z range (example: 4514 2ZHH 007CR).
MFP printhead adjustment
After re‑installing the current LSU or installing a new LSU, a mechanical and electronic LSU adjustment must
be performed. Before starting the LSU removal, disable the scanner in the configuration menu. After removing
the scanner assembly from the MFP, remove the control panel assembly from the scanner. Attach the control
panel assembly cable directly to JUICC on the controller board.
