Fixing “108.08” error on a lexmark C546dtn printer

The printer that I have been using for quite some time recently stopped working. The display indicated that the error is “108.08”.

A quick search got me the service-manual for this printer. This is a really great document. It has all the instructions needed to diagnose and fix an error. Detailed disassemly instructions can also be found.

I did all of that, but instead of replacing the printhead I just cleaned it. Over the time dust does accumulate on the windows where the laser light exits the printhead. After disassembly I could clearly see that the windows were cloudy; colorful toner could als be spoted on the windows. My solution was to use a kimtech wipe without any water/solvent to clean the lenses.

The manual actually says to clean those windows, but its on another page/section not directly related to that error.
