Hi there,
iR1600 are special machine that needs a little bit more care.

First, clean the laser unit and optics ( beneath copy glass too ). Then use some polisher and polish the developing cylinder and clean/replace developer cylinder blade.

Use GENUINE CANON DRUM UNIT and GENUINE TONER.

Is it the same image being repeated ?

If so then it is the drum not the developer unit.

There is a device for discharging the image once it has been transfered to the paper from the drum.

If that is broken then the image is not cleaned off and will repeat.

The other thing to look at is your setup to make sure it is set at A4 and it is being told to print one copy per sheet

If you the image is faded and your toner supply is good, the problem is the developer blades in the imaging unit. During the normal use of the printer, there is a buildup of toner that sticks on the developer blade. The developer blade meters the amount of toner that gets to the drum that ultimately makes it to the paper. As the toner buildup increases on the blade, less and less toner that gets to the drum cause the image to fade.

To fix this problem you will need to disassemble the imaging unit and clean the blades or buy a new imaging unit. I have clean my blades and I don't have 20000 images it is about 7000 and I have a document to show you if you are handy.
