Hey you!
This is what an engineer would check for, and do: (if one step does not help, go to next step)
1 Check for obstructions between the Laser Unit and the Imaging Unit.
2 Remove the Imaging Unit and inspect each OPC Drum and corresponding area.
3 Remove any debris such as hair, foam or paper. Remove the obstruction or debris.
4 Replace the Imaging Unit
5 Replace the Transfer Roller
6 Replace the Fuser
7 Does the image quality improve?
8 Do not clean the Developer Assembly rollers with a cloth. Carefully remove
debris from the rollers using tweezers or similar tool.
9 Remove the Developer Frame Assembly. Using a lint free cloth, carefully clean the Laser window and between each Developer Assembly.
10 Replace the Developer Frame Assembly
11 Replace the Laser Unit
12 Replace the Engine
Best Regards
Kimzi
