Introduction

Your printer is bound to collect dust over time, and a lot of this dust rests on the underside of your scanner glass. This affects the quality of your scans.

Cleaning the scanner glass is fairly simple: the scanner tray must be removed prior to removing the scanner glass.

Proper cleaning of your scanner glass will require alcohol and a lint-free cloth.

I thought my printer was a goner for sure, then I stumbled on this site. All I had to do was clean the glass- it looked terrible!- and put it all back together. It was easy. I truly appreciate not having to get another printer- THANKS!

This saved me and my printer!! Thx so much! In fact, the dust flocks were just against the internal buses and under the control panel. And I also found out that one can check most of the machine without having to uncable the grey ribbons.

Handle with extreem care though.

Thx thx thx!
