Question about Brother MFC-9440CN Laser Printer

Pages printing very dark

When printing or copying the pages come out totally black. I have replaced the drum and toner. When I replace the toner, about 20 pages come out fine, but then they are all black. Help!

    Actually, it was the toner saver option. Once we turned it ON, the copies are coming out okay.

Sharp 1641cs - Dark/black page after replacing drum & toner


Hi you have not said the toner type you replaced with though that will give not completely black copy. The problem may have been the drum unit installation. Make sure the charge unit over the drum service is present ie the one with a mesh wire like grid. If present, clean it or wipe with a soft clean and dry cloth. Clean the saw-tooth like metal plate inside that unit by slow blowing and make sure no toner particles are there. Finally screw the unit properly on the drum unit and your problem is solved.

Prints are having black lines and smudges along the sides of the paper. What do i need to clean?


Unfortunately when it comes to toners and drums there isn't much that can be fixed with cleaning. It sounds like either your toner cartridge is worn or defective and spilling toner, or your drum could need replacing and therefore is acting up. To check if it's the drum, pull out the drum unit and look at the drum roller (but don't touch it!) you should see streaks or color changes on the roller in places matching where the smudges on the paper are if the drum needs to be replaced.

My bet is on the drum. Drum units are fairly easy to get a hold of, since it is a "replaceable" part of the printer. And if you can install the toner you should do fine with the drum unit as well.

Hope this helps, good luck!

My Brother HL2140 printer was running fine and all of a sudden the toner light is on and it stopped printing. Just yesterday when i printed out the status for the drum and toner it showed more than 80 %...


636 is a lot of pages and depends on the toner coverage you may need to replace the toner.. 80 - 75% (is that used is remaining ??) any way check your waste toner basket first (see you manual for instructions) chances are its filled and needs cleaning or replacing (see your manual for instructions) If its fine then change your toner .. If you have the demo toner (toner shipped with machine) these contain less toner than a new cartridge and will finish faster ...

Replaced fuser and toner units now only prints black pages


Printing on a laser printer has 3 steps:

1. electro-statically charging the "drum", at various tiny "pixels",
to identify where the toner-powder should be placed.

2. feeding toner-powder onto the charged drum.

3. making the fuser produce heat to "bake" the ink onto the printer.

So, a failing unit or failing electronics would "charge" *ALL* of the drum,
thus putting black ink EVERYWHERE onto the page.

Take the printer to a qualified technician.

The copies comes out totally black


H2 00 Thermistor open, your fusing unit needs to be serviced (cleaned or replaced)

The black copiers can be a number of things a few things to check and what the remedy could be;
  1. Open the right door, if you notice a lot of toner/developer spilt then you could be having a charge corona short (built onto the drum unit) clean corona
  2. Open the right door, if you drum (green or blue cylinder (depending on brand of drum) under your fuser) is coated with toner (should be all green/blue) then you could be having a drum short, replace drum unit for this.
  3. Open the right door and on the door towards the bottom is a metal unit with a white guide built on it (transfer corona) if there is a lot of toner/developer in it (looks dirty) then this needs to be cleaned or re-built.
  4. You also could be having a board issue causing the black copies.

My copy machine will just print a totally black sheet of paper.


Pull out your toner cartridge, push back the drum shutter and see if the drum is coated in toner. If so, it is defective. Replace it and it will be fine.

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.
