Instructions for the Canon MF6590 – MF6530 Fixing Unit Removal Procedure

Paper jams in the fusing unit area are dang near impossible to remove without removing the fixing unit. If you ever look at these machines then you would think the fixing unit comes out easy but that is not the case. These things can be a pain to remove and if your not careful you can break the exit drive gear shaft. Therefore, below you will find the Canon MF6590 – MF6530 Fixing Unit Removal Procedure instructions along with pictures to help make the job easier. Now I did not include removing the back and front covers and the left side covers as that is easy to figure out compared to the fixing unit. If you can’t figure those out then you probably shouldn’t be removing the fixing unit.

Fixing Unit Removal
The height of the fixing unit is adjusted at 2 mounting points at the front (left door + front cover) prior to shipment. If you need to detach the fixing unit, apply 2 markings before detaching the unit to enable you to return the unit to its previous position. When replacing the fixing unit with a new one, carry out height adjustment.
1. Detach the rear cover and front cover, and then detach the rear-left cover.
