Question about HP DesignJet 450c InkJet Printer

Black smudges on printed page

Printing results in dark black smudges of ink along sides of paper or within 2" of edge of paper.  This is especially noticeable when trying to print index cards.  I have tried various thicknesses of paper and cards, but seldom have clean printed copy.

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....).

My dcp165c printer print quality prints black & yellow colour. i clean print head through maintance 76 but problem cannot be solved


How is the printer printing black and yellow color? Is it a smudge?

When I print, the pages are smudged with ink. What should I do?
Description:
- If smudged stains appear at the top center of the printed page:
  • Make sure the paper is not too thick or curled.
    Also, verify that the appropriate paper is being used and that the paper type set in the machine matches the media used.
  • Make sure the paper is not curled when you print on the back side of the paper with the Print Odd Pages and Print Even Pages settings.

- If smudged stains appear at the right or left corner of the printed page:
  • Make sure the paper is not curled when you print on the back side of the paper with the Print Odd Pages and Print Even Pages settings.

- If smudged stains appear on the reverse side or at the bottom of the page:

Broad dark line on right edge of copied papers


If you have the black line on copies and scans but printing from P.C is fine, then your scanner is broken.

Contact your printer manufacturer for a replacement or repair.

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.

Samsung scx5315f printing black smudge along edge of page


The fact that it's printing anything suggests that it is not a Toner problem. Remove the toner, and have a look at the run inside the printer, checking for any excess toner which is in there. Also, check the Drum and Imaging Unit for damage, wear and tear etc. There will also be a static strip near the imager, with a little tab which you can sweep across the unit to clean it.

Black smear of ink at end of lines


Please load the printer with at least 10 sheets of plain paper then press the start button. This will dry or clean any ink found on the rollers.
Continue to run blank pages through the printer until no more ink is found on the paper, then attempt printing. If ink stains, streaks or smudges are still present, the printer may need service.

Black smudge streaks on rightside of printed/copied material


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.
