Laser scanning unit (LSU) service check
Action Yes No
Step 1
Make sure that the LSU and controller board are compatible.
•
Check the serial number of the printer to determine whether
the LSU is galvo or polygon. 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).
Note: Galvo and polygon LSU parts are not interchangeable.
•
Check the color of the controller board. For galvo LSU, the color
of the compatible controller board is green. For polygon LSU,
the color is blue.
Are the LSU and controller board compatible?
Go to step 3. Go to step 2.
Step 2
Replace the LSU or controller board with a compatible one.
Installation note: Mechanical and electronic LSU adjustments
are required to complete the installation of the LSU. See
“Printhead assembly adjustments” on page 276 .
Does the problem remain?
Go to step 3. The problem is
solved.
