Question about Brother DCP-7020 All-In-One Laser Printer

Toner not fixed to the page, rubbing off

Having replaced both the drum and toner recently, I don't know which caused the problem. Now, images that print on page can be smudged off to the point of not being readable because they are too faint. Does anyone know which is defective: the toner cartridge or the drum? Thanks in advance.

    It seems to only be a problem on my gray envelopes that match my gray letterhead (25% cotton paper). Printing on white paper or white envelopes seems fine.
    Is this something that can be adjusted? Can the fuser be replaced? Or is this just something that wears out over time through constant use?

    Thanks again. At least I am avoiding chasing a solution by replacing toner and drum cartridges, which would have no effect on my problem.

    White envelopes are Staples standard white envelopes, 24 lb paper, white "wove". No cotton apparently.
    Thanks in advance for any help. I'm lost.

The fuser (a large roller near final exit that is heated) is not reaching proper temperature. normally, it should be too hot to touch.

    this does change the solution.
    are the white envelopes also 25% cotton paper? I want to narrow down any derivatives. Don't do anything with fuser yet...

What causes my copier pages to have black smudges on them.


Black smudges are usually caused by a defective or worn out drum. When the drum gets a fingerpirnt, any kind of oil, or anything else that causes the static charge to not hold the toner to the paper, the toner will not go where it is supposed to in order to create the image on the paper and it will cause smudges, streaks or lines.

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.

Smudging across the page.


Here is a generic question I would like you to consider.

"
Are you using a factory new ink cartridge?
If you are using a refilled or third party cartridge that may well be your problem. Most manufacturers build logic into their products to prevent the use of “Other Equipment Manufactured” cartridges as well as re-filled cartridges.
They do this to prevent problems from contaminated inks causing problems with print quality or damaging the physical printhead.
If this does not apply to then do not worry about it.

My concern is that the gunk you are seeing is caused by toner leakage. To the best of my knowledge, current day drums cannot be serviced. They have to be replaced. Wiping the drum will scratch the surface and you would still need to replace the drum.
Also, it may be that you are at the "End of life" for the drum.
My suggestion would be to have the printer serviced by an authorized repair technician.

Vertical dark/smudged line on right side of paper when printing


See its a very common issue.the right side of the drum has moisture on it.remove the toner and drum and apply a hot air blower on it for some time also clean the printer internally.reinsert the toner and drum.
check by printing few pages the smudging on the right should go within 10 to 12 pages.
if the smudging doesnot go away then its time to replace the drum to solve the issue.

This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya.

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.

Skidmarks on the printout


Time to think about replacing the image drum unit. Excess toner is not being cleaned off properly and is winding up on your printed pages. The drum unit is separate from the toner cartridge, and you normally replace the toner cartridges several times before needing a drum. Replacements are available from many online sources and at office supply stores. Generic replacements run around $50 and the original part is around $100.

Smudge marks on paper; otherwise normal


fuser is usually replaced as a assembly, it's the hot bit a back.

Can only be two things the drum or the fuser as our headstrong friend has correctly explained.

More than likely it is the 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
