Laser Printer Light image solution!

Sometimes, a Laser Printer gives out pages with the matter lightening towards one edge of the page. If the cartridge is alright then the problem lies with the Laser Scanner Unit (LSU).

Note: Please try this fix only if you really know what you are doing!!!!

Locate the LSU (usually a black colored box). Open it. Inside, you should find a Hexagonal Rotor. This is the Mirror Unit. Clean each face of the rotor with a Very soft tissue lightly moistened with IPA solution. Clean the lenses (one on the laser window and the convex one inside). reassemble the LSU.

Problem shoul;d now be solved!
