Black smudges across sides of 81/2 x 11 paper

I'm trying to make a copy, but one side of the paper keeps on coming out with black smudges. I've cleaned the platen glass and platen cover but that didn't work. Any suggestions?

The optics may be dirty or you could have a bad drum cleaning blade.

5x7 inch paper moves towards end of print and black ink smudges edge of paper


Check for any small paper jam. Check the rollers, also use an alcohol swab to clean the rollers and check for ink leaking. Check you ink pad, it could be time for a new one.

I have a Canon Imagerunner 1023if and have black smudges along the left edge of paper, both copies and printed directly from computer.


this is possibly a problem in the fuseing part of your machine, where the paper heats up at the back, the fuser roller could be worn out. and your toner could be sticking to it.

Black smudges on printed page


Are you sure this is a Designjet 450 (large format printer) and not a Deskjet 450 (portable printer)? The following assumes you have wispy black streaking on the printed side of the paper. If the streaking is on the back side then post more details of the printer model and the issue.

In either case the most likely cause is a buildup of fibers on the underside of the printheads or carriage, causing wisps of black ink to be dragged on the paper when the carriage reverses direction. You can clean the printer as shown at the following (though the details will be somewhat different for the Designjet or Deskjet....).

Black strip Mark on paper after print


Ramana is the black stripe just showing up on copies or faxes or does the stripe occur when you are printing from your computer. If the stripe only occurs when copying or faxing then more than likely the scanner glass is dirty. White out liquid on the scanner glass is a common.If it happens when printing fromyour pc, the problem will be in the toner cartridge or the fusing assembly.
Change the cartridge first to see if it goes away. Check the scanner glass, especially the small glass strip on the left side of the scanner or the right side where you place the original paper. These areas should be completely clear and clean of any scratches or smudges.
Last is the fusing assembly. If you tried everything else and theline continues to bother you, the fusing assembly sleve is probably torn. This would have to be replaced. The part number is RM1-0865-040CN.

I'm sorry to tell you, this is likely a drum issue.

You probably need to have a certified engineer examine the machine.

Have you tried speaking with the local service center to see if they have experienced similar issues? It might be free information.

PC-65 (Canon copier)


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.

Black smudges on copies


Hi, try to pull out complete process unit(cartridge) with toner box .You have cleaner(blue or green color) move this cleaner from right to left side 4 or 5 times.Note that cleaner MUST be in home position-right side when you finish.Check print.
If problem still persists, you must do following:take away small grey plastic cap on left side of cartridge,then push complete charge corona(part with cleaner on top of it) to left side just enough to lift right side of corona from cartridge.Pull out that corona and you can see drum and developer roller. Turn the gear on drum,and look for smudges on black developer roller.Try to clean smudges with brush or with dry cloth.Toner will again attract to that area,but regular.
