I have the Canon ImageClass MF726CDW and it Prints Vertical Yellow line on the left side of the page.
My i had the printer for 2 years and had no problems printing, with same type of toners.
Now for the last few weeks it started to have those vertical yellow line, is not a line, is like 1 inch wide line on the left side of the page...
Here is a picture:
I pulled the toners out from the tray and the yellow toner is the last one, and i am seeing some yellow mark on the big belt or whatever is called that i guess paper goes on it, i clean some ,but i can not turn it, from the front of the printer, unless a back cover can be taken of and have easy access, and also how to release the belt so i can manually turn it and wipe some .
What you think it maybe?
Thanks for any advice.
I understand your Color imageCLASS MF726Cdw prints a vertical yellow line down the left side of pages. If you have not already done so, to restore your print quality, I suggest you clean the fixing unit and transfer belt using your MF726Cdw's operation panel using these steps:
Follow these steps to clean the Transfer Belt:
