I would suggest you have a drum earth problem, either with the coating or earth tab in the drum.

Change the Drum or Charging roller.

This is copy sample! How's print quality?

Re: canon ir 4570 peoblem

If that interval is 95.5mm you've got a drum ground issue. All the solutions include replacing the drum unit.

Possible causes:

Normal wear of the drum coating. Any place where the coating is worn through to the aluminum core, you'll get drum ground bars.

Loss of drum ground. You can measure the resistance from the aluminum edge of the drum cylinder to the frame ground. It should be very close to zero ohms. I've seen the copper contact in the rear drum cap start to arc, and burn up the copper contact.

You say you replaced the drum, was this a genuine Canon Drum Unit or just a drum kit etc?

Re: canon ir 4570 peoblem

If only does it on copying and not printing(as you state), you have a reader issue. Cable to CIS could have breaks in it...

i replaced like this

I REPEAT>>>IF PRINTS ARE GOOD AND ONLY HAPPENS ON COPIES,IT IS A READER ISSUE. This isn't rocket science. Stop guessing and start troubleshooting. Prints are good....why would you suspect the drum? I'm done with this thread

Re: canon ir 4570 peoblem

You only replaced the drum, you need to fit a new drum unit, the compatible parts cause so many problems!
