Usually its a defective toner cart. recycled carts are just refilled, they are not reconditioned. I would remove that cart, clean the mechanism, and replace with a new cart.

Smudge line on side of page


Smudges are most likely from the toner cartridge. If you can take your finger and run over the print and it smudges, then it is the fuser.

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.

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:

Cannon Pixma MP500- I get a solid black line on the reverse side of a printed page. Went through all the cleaning procedures and new cartridge, no change.


For some reason, the printer is designed to dump ink into the bottom of the tray before feeding on the paper. The paper is then dragged over the ink, leaving the black line. This is a software issue, not a hardware one. I'd advise that you update all of your print drivers, as well as your firmware.

A temporary fix is to clean the rollers and base plate of the printer for ink spills.

Check for any bits of paper or debris that may be caught in the printer. Be careful to feed in the paper perfectly straight, as this printer does not have good rollers, and it will cause paper to break off and cause problems. If any debris has caught or absorbed ink, it will cause the back of the paper to smudge, and you have black lines.

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....).

Printing greetings cards and envelopes


At the moment it is printing both sides of Greetings cards, but this printer appears to be very sensitive with regards to placng card in the exact position in the paper tray.

Why it will not print envelopes without smudging I still don't know, so I shall just have to write address by hand after I place graphic on the envelope

This 5300 was a Christmas gift from my wife and if I could afford to change it I would. The performance is very dissapointing

Kindest Regards
