SOURCE: spots on page

You need to clean the drum unit (use a soft cloth and/or a soft paint brush) and also slide the blue slider a couple of times to clean the wire.

SOURCE: Black toner spots appear on print outs

You have something stuck on your drum. See page 125 of your manual to clean it--it's just isopropyl alcohol on a Q-tip, but don't scrub. This happens (too) often to some people I know.

SOURCE: I purchased a new Brother TN-350 Toner, however

There's toner on the roller or the fuser wire needs cleaning. Open the printer, remove the toner cartidge and clean the inside of the printer with a soft brush.

When printing black dots appear chaotic, over the entire sheet of paper. What to do?


If the black dots appear on every sheet of paper it could be the fuser unit is wearing out or the drum unit. The way to check that is to stop a print half way through and remove the paper. If they are not there before the fuser unit but after it then it will be the fuser. Or if they are there before the fuser unit it will be the drum unit. If it they only appear specfic to one source then it is likely to be the source of the document. IE copying - check the optical area (scan glass etc). If on incoming Faxes it may well be the sender that has the problem and is just transmitting them to you. Hope this helps.

There's a small black "x" mark on every print on our Xerox C75 digital press.


Hi,
The only thing I can think of is the IBT belt might have a mark on it. If the 'X' mark is in the same place on each print, regardless of size A3 or A4 then the problem is being printed intentionally e.g. within the file, if it's more random then it could be the belt. Is it only in the black, if so recheck the black drum. Is the mark on the edge of the paper it could be the cleaning system problem.
This is one problem that would need to be seen.
Good Luck.

Black smudges down left side of page


How do I clean white or black spots on printed documents? Description: First make 10 to 15 copies of a blank, white sheet of paper.
If you still see the spots on printed documents after making multiple copies, clean the drum unit as follows:

  1. Remove the drum unit and toner cartridge assembly, and then remove the toner cartridge from the drum unit.
  2. Position the print sample in front of the drum unit so you will know the exact position on the drum that is causing the poor print.
  3. all-ug-19.gif
  4. Turn the black gear on the drum as you check the surface of the OPC drum.
    The OPC drum is photosensitive so do not touch it with your fingers.
  5. all-ug-20.gif
  6. When you find the substance on the drum surface that matches the print sample, gently dab the surface of the OPC drum with a cotton swab that is lightly dampened with isopropyl alcohol.
  7. Note
      • Do not use a scrubbing or wiping motion because this might damage the drum.
        all-ug-21.gif
      • Do not try to clean the surface of the OPC drum with a sharp object, such as a ball-point pen, because this might cause permanent damage to the drum unit.
  8. If the print quality still has not improved you need to install a new drum.

Paper when out put then see spot in middle page portate


I don't know the model of Canon Copier you have, and I don't know if your problem happens when you copy and print, or only when you copy, so it's hard to tell with the little information you've provided.

Let's assume the easiest solution is the correct one...

Is the "Spot" in the same location on every copy? Then clean glass.
does the spot move left to right across the page with each successive copy? Then replace the drum unit.

HP color laserjet 1600 - black spots on paper


It sounds like the toner drum may be having some issues, it can be replaced but it is not easy / inexpensive. It may be more cost effective to replace the unit. Otherwise it will need a replacement part for sure.

BLACK LINE ALONG RIGHT SIDE OF LETTER SIZE PAPER


Is this and Okidata C5100? And is the stripe vertical up and down on the page? I'm going to assume yes to both of those for the sake of trying to help. Worse case is the fuser unit in the machine is wearing in one spot and thats why the streak is appearing. Also, many color printers require a seperate drum unit or photo conductor unit. These could have a wear spot on them as well. They can fail long befor the change drum light appears. Other than that remove and inspect the black cartridge. If there is a shutter on it, pull back and inspect the two inner rollers. You're looking for any wear spots in a location that corresponds to the streaks on the paper...or an excessive amount of toner leaking from one spot on it. Hope this helps!!

4250tn print black spot


You either have a bad spot on the drum or a bad spot on the fuser rollers. Replace the cartridge first. If spot continues, take cartridge out and get inside with a flashlight. You'll probably find a piece of paper stuck to a roller.
