Leaves black marks on copies

It could be leaking toner from the recovery area that sis on top of the dum, it removes any toner that was not transfered to the paper. You would have to remove it and empty out the toner.

Copies have ink smudges at top of all pages. Canon Imagrunner 2000 model. It seems that the toner is showing up on each copy.

this is problem with fixing nip - pressure between fixing roller and silicon pressure roller.
To fix this you need to change the fixing roller, bushing of fixing roller and maybe silicon roller.

Call service!

Hope that helps!

The ink is smearing on to the copy. The text keeps on reappearing on the page.

It sounds like either your drum needs to be replaced (needs to be done every 5 or 6 toner cartridges), or you have a bad fuser (depends on what you mean by smearing).

When an image reappears further down the page (not as dark or bold) it usually means that the current in the drum is not correct, or the coating on the drum is worn. Take the cartridge assembly out and separate the drum from the cartridge. DO NOT TOUCH THE DRUM ROLLER. Look at it and see if there are streaks, color differences, or toner on the drum roller. The roller should be solid purple or green with no marks, lines, toner, or smudges on it. If it does, the drum is a replaceable part and you can get one anywhere that sells toner cartridges. They are even available in remanufactured brands.

However, if there is loose toner on the paper (wipe your hand over it and it comes off), then your fuser is bad and needs to be replaced. Another problem with the fuser you can check is whether there is toner being adhered to the fuser rollers, which could cause smearing and images to reappear on the page. To check this, open the rear cover of the printer. Inside you will see two rollers: usually an orange one on top of a black one. Be careful; the fuser can heat up to almost 400 degrees, so let it cool if you were just using it. Check to see if there is any toner on these rollers; if working properly, they should be spotless. If there is toner visible on either roller, then you may need to replace the fuser.

It is a 75% chance of your drum being the cause, which would be the problem to hope for. If your fuser is bad, in all honesty it may not be worth fixing; it can cost you up to $150.

I hope this helps! Good luck!

We have a Ricoh Aficio CL3500N. We are getting a

Never clean or touch the Transfer Roller (spongey rooler) unless your using a dry cloth or vaccum as last measure.

Usually the transfer roller sits on a drum/pcu specific to that color. If you can tell which color is sitting on to of the roller replace that drum/pcu.

A smudge across the copy can be in many different areas.
Some ideas.
The drum cleaner may be the problem as you indicate.
It may be a piece of paper ripped of dragging across the surface of the paper causing the smudge.
Also the fuser roll coating may be very worn and causing that.
One thing to try that can show you if the defect is on the drum cartridge, is start to run a copy, After the paper feeds and this is timing, shut the machine off when you think the paper should be about half way through the copy cycle, then see if the copy defect is on the unfused page, If it is smeared before it reaches the fuser, it is in the cleaning section, if it is not smudged, then it is most likely the fuser rollers are needing replaced.
First look for a paper fragment in the path, step 2 is to shut the machine down in mid copy and see if the defect is there.
The fuser is the hot area of the machine in the exit area, If you can take a flash light and look in there and see if you observe wear or heavy toner buildup on a roller then obviously thats the problem.

"Clean drum" doesn't get rid of smears.

Need to change cartridge, the residue is not being cleaned off by the Drum Blade.
