SOURCE: My printer- Brother HL1250- is making grey streaks on the paper

More than likely the grey streaks are from dirty fuser rollers open the fuser area and insect the fuser rollers i think they should be grey take silicone lubricant and wiat ntil rollers cool down and clean with a coton cloth do not scrape with anything sharp if this does not work then you ned to remove the glass platen and clean the optics( mirror and lens with tissue and glass cleaner wen machine is not hot also insect expsoure lamp( do not touh lamps because the oil from your hands will cause the lamp to get extremly hot and burn out good luck

One other thought is there could be marks from the stripper fingers at the fuser section look for build up of toner on them if so clean with q tip and alcohol

SOURCE: laser printer horizontal streaks go away after a few pages

The operating principles behind laser printers are fairly simple. In fact, Brother machines more closely resemble large copiers than conventional laser printers, this is why they are so reliable.

There are a couple of things to look at:

On the drum unit: is the imaging drum worn or scratched? When did you last clean the corona wire?

If the drum is scratched or otherwise with defect it should be replaced. If the corona wire is dirty it can fail to properly charge the drum and lead to print defects.

On the toner cartridge: Does the toner roller have any noticeable lines or banding in the toner?

Behind the toner roller is a "Doctor Blade" that ensures an even and consistent coating of toner. If there are lines in it they can produce print defects as well. Lines would be likely caused by toner accumulation on that blade. If there are lines, are you are careful, you may be able to clean the blade by gently and slowly scrubbing the non adhesive end of a post-it note between the toner roller and the doctor blade where the lines are.

Hl4040cn will not print test page


Try doing a machine self test to ensure that it is working properly.
Press OK/return to "Machine Info"
Then down arrow once to "Test Print" and OK/Return.
The machine should produce a self test printout. If the machine does not give a print out, try cleaning the paper pick up rollers at the back of the paper tray cavity. Be careful, the machine is heavy.
If a full test print happens - Your printer is working fine and the problem is at the computer end.
It's possible driver installion is faulty or incomplete and you should try re-installing the printer driver. Is it also possible that your printer paper settings are either incorrect or do not match the paper in the printer. Check and match your paper settings in the printer preferences and the paper tray.

MFC8500 VERY DARK STREAK (.25 INCH WIDE) RUNNING DOWN THE ENTIRE WIDTH IOF THE PAGE.


Reference page 22-17 in reguards to cleaning the charge wire on the drum unit and page 22-16 for cleaning the document scanner. This is a link to your Brother MFC 8500. Hope this helps.

If the dark streak appears on printed documents, cleaning the charge wire will correct it.

Faded-out streak


check your ink levels. if its the ink that came with the printer it is probable running out of ink. they do not give a full cartridge with printers, only about 3rd full. also try cleaning the heads. and try changing your printer settings/prefrences to less ink, more drytime see if that helps.

Streaks and faded spots


I had the same problem. Your printer might be in 'envelope' mode. open the top of the printer and look towards the back. You should see two grey tabs with envelope symbols on them. make sure they're pushed down.

Try that
