Canon MF624CW Printing Red Shadows


Hello all, I'm here because I have not been able to find a successful resolution an issue that recently cropped up with my otherwise trouble free colour laser printer. It's an MF624CW, and have had no problems at all with it. It doesn't get heavy use and as such am still on the original colour cartridges. Only the black has been replaced in the past year and have had no print quality issues until recently. 


Suddenly when I print a text based document, the letters are all shadowed with a red colouration that makes the letters look as though they are meant to be viewed with 3D glasses. The effect is a slight blur and it's hard on the eyes to read. I have no clue what could be causing this. My experience with printer alignment issues extends only to inkjets. I am not even sure lasers can be aligned. Your assistance in this matter would be greatly appreciated! 



I should add that I have just tested using a PC and it prints fine from there. The printer issue occurs only when printing from my Mac via wireless. The PC is connected directly via USB.
