Re: black smudge streaks on rightside of printed/copied...

Can only be two things the drum or the fuser. More than likely drum they last about 4 toners i think.

Learn the art of getting a page to stop halfway threw printing, you want to stop the page after the drum has put a image on the paper but before paper has gone threw the fuser (hotbit).

Once you have mastered the position correctly by stopping the printing by opening the door and removing drum/toner cartridge, to reveal the paper that is printed but can be rubbed off, we will know if marks are coming from the drum (you will see them) or from the fuser, if print is fine.

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.

Printing has smudge on edge

If it is right along the edge then the drum (well the cleaning blade of the drum) is faulty. In a unit like that I suspect it is all part of a toner cartridge. Try replacing that and I think you will be good.

4 - black ink smudges (1/32" wide x 1/16" high) in right margin

Very nice trouble shooting. The image defect you describe point to the OPC or drum unit this is essentially the toner cart. In your case black. Measureing the distance between repetitive defects is a sure way of diagnosing problems such as yours. Again nice work.

Google repetitive defect ruler for your model to help in the future.

Hope this helps

If you are to both of these it could be wise ordering a printhead, but this is mostly caused in the uk by None Canon Paper.

Please let me know what you are using?

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....).

Cannon Imageclass printing problem

You need to check your glass first to make sure it has no scratches. Then you can run a copy and open door to stop paper in the center of the machine, b4 it goes through fuser. If line is on copy, you have a bad drum. If not your upper fuser roller is bad.
