Canon image runner 220 leaves grey streaks when I make copies

As in the machine leaves patterns on the carpet? That's totally normal. If its leaving dirt streaks, its not operating correctly.

Check for white-out or some other dirt on the scanner head, the piece that moves from top to bottom to scan the item to be copied.

Hi,

It's a common problem with modern machines.
Due the modern way of washing on low temperatures some dirt will stick into the machine's.
You can try to wash some old stuff several times on a high temperature and instead of using washingpowder you have to use a handfull of soda.
It will clean the inside. Worked fine overhere.

Good luck,
Gerard

Is this problem appears when you copy from ADF, but not from platen copy glass?-If Yes clean the ADFs copy glass

If the streaks appears horizontal or vertical?
Check the drum unit and/or fixing film

Your drum unit has an Estimated Drum Yield of 26,900 Copies

Sounds like it's time to replace the Drum.

Sounds like there are multiple problems on this machine. Dirty optics can cause light images, white streaks can be caused by dirty cortron wires(becareful when cleaning the wire or all the wires 3 usually, Q-tip can help) , not enough toner in the ink hopper, dirty cleaning blade in the drum modual. A bad heat roll can cause streaks also. Background with light images and black spots can be caused by competitive toner not working very good.

Try to print something, if there is any streaks?If no the problem is in copy glass (dadf or platen glass).

If there is streaks on print also,it could be the drum unit ( pull the drum unit out and see if on drum surface is any black streaks), fixing film is worn out, and in the worst case you have problem with toner unit ( on toner unit you have current leackage ) and you need (in best case) clean the contacts on toner unit, and in more expencive case tochange the toner unit.

look on the drum ( shiny cylinder).
most likely it is moving on each page, same image but different spot on the same side.

hmmm..let's see..sounds like you have some residue accumulating from something possibly seeping into the tub. That can be old rubber, a metal sheath, or even an leak of lubricant. Like an old car, there are parts of every mechanical device that need to be attended to.

I'd recommend you find the most seasoned person that works on older machines, to come by and assess what is 'leaking' on your clothing. Grey comes from something metallic or rubber/plastic.

Hope you can solve this one, and keep that old machine happy.

Change  drum or fuser.
Take out drum is there a black ring on the sides? change 
take out fuser is it worn on the sides? change.
