Question about Canon PC-940 Black and White Copier
When I copy it leaves "tire tracks" the length of the page only on the back side of the copier! It sounds like the fiber optics are dirty from the test I ran checking whether it was the fuser or fiber optics. Can you explain how I clean the fiber optics and where they are specifically as there is no repair person in my area at all! Thank You, email@example.com
My Canon 940 copier leaves a 1/2 soft black track on each copied page. I removed the cartridge, opened it up observing a smudge on the red bar approx the same place that is on my copies. How do I clean this? THanks.

There are no fiber optics in the copier. It has 6 mirrors that send the image to the drum unit. Did you try to clean the copyboard glass? Also, do the marks move up and down the page? Also, have you replaced the drum cartridge recently? Pull the drum unit out can you see track marks on the drum it self. If not I would have to say it may be comming from the fixing ass'y, the hot part of the copier. Try to use a dry rag and wipe up any loose toner in the paper path then try to run some blank pages in the copier this may clear up the problem...
