The toner might be bad, because the old cartridge is working fine.

Black marks on pages when i print


Do the streaks get fainter as you print more pages?

It sounds to me like have toner on your rollers/fuser.

Print out 10 prints from the printer and see if it improves.

If you remove the fuser wiper cover from the top of the printer and look down you will see part of the fuser roller (DON'T TOUCH VERY HOT) and check if there is toner on it.

I have black streaks on my 1600n prints. I have tried cleaning the drum, however the streaks still exist.


Dirty print out is basically due to cartridge related issues. Take out the cartridge and clean its drum/ (green roller) with a dry, soft, lint-free cloth. The drum is usually located under a cover. Checkout for any spilled toner inside the printer and clean it also. Print a few pages so that the parts get further cleaned. I think, this would solve the issue.

Moreover, black streaks (thicker lines) and dots etc indicate faulty PCR Roller which is located behind the green drum inside the cartridge. Cartridge or get the PCR Roller changed by a professional.

Let me know if any further clarification is required.
GoodLuck!
Dont forget to appreciate the solution if I could have been of any help!

I have a BROTHER MFC- 8860DN that makes black streaks on copies


If this is only happening with copies and not straight prints, it is possible that the problem is with the scanning unit. Use the soft cloth to clean the scanner area to the left side of the machine where pages are scanned when run through the page feeder. A spec of dust or other debris in this area will appear as a streak along the length of the page.

If it occurs on all prints, You may need to replace the drum or clean the fuser unit.

New toner prints very light. No setting changes on printer.


I had a similar problem, it turned out to be a cheap toner cartridge. Replaced it with an HP cartridge and have had any problem since.

Prints black vertical line at bottom of page on every print. HP 8550gn


This should help -

Developer streak
Developer streak is characterized by a line of dark or missing toner
that stretches from the leading edge to the trailing edge. Replace the
toner cartridge corresponding to the color of the developer streak (for
example, if the streak is magenta, replace the magenta toner
cartridge).

Repetitive defects troubleshooting
Repetitive defects are defects that occur in the same vertical position
on the page, but not necessarily on every page. Most repetitive
defects are caused by problems with one of the following, and are
indicated by the positioning of the defect on the page:
 developer roller (at 38 mm)
 charging roller (at 44 mm)—see additional information under
“Charge roller set” on page 454.
 cleaning roller (at 56 mm)
 developer DSD wheels (at 65 mm)
 transfer roller (at 66 mm)
 transfer drum (occurs once per 11-by-17 inch or A3-sized page,
or every other letter- or A4-sized page)
 fuser (at 150.5 mm)
 imaging drum (at 195 mm)
 transfer belt (at 222 mm)

2 IN. GRAY AREA DOWN SIDE PAPER


There are several things that can cause this. A worn toner cartridge and/or transfer roller can cause vertical smears, but it may also be a worn fuser assembly. The teflon coating on the fixing (heat) roller wears off, and leaves vertical streaks of varying widths on the pages. Sometimes you may see "ghost" images on the pages for the same reason. Open the back door of the printer, and hold down the exit guide on the fuser (carefull, it may be very hot). There are two long rollers, the lower one is black, the upper roller is either grey or shiny brown. That's the teflon coating. See if it's peeled or damaged. If so, replace the fuser assembly.
