I have been getting these colored lines on the left edge of all of my prints. Any suggestions on how to correct this issue? Thanks in advance. MF735Cdw

Greetings ,

Are you using OEM Canon brand toners by chance? 

Open the printer cover and carefully slide out the toner drawer.  Remove the cyan toner.  Do you see any splatter inside the machine that may be transferring during paper transport?  

You can also initiate a ITB transfer belt cleaning from the printer's control panel.  Toner residue stuck on the belt will transfer to the paper and appear on each printed page.

I have only ever changed the black as I do not print a lot. So they are all from the factory. I will investigate your suggestion. Thank you.
