Toner density sensor service check
Action Yes No
Step 1
Remove the transfer roll, and check for loose toner blocking the
toner density sensor.
Is it free of loose toner?
Go to step 2. Clean the sensor.
Step 2
Check the toner density sensor for proper operation:
a Lower the ACM assembly.
b Move the toner density sensor wiper from left to right.
Does it move freely?
Go to step 3. Reinstall the wiper
properly. If it still
cannot move freely,
replace the toner
