Question about Brother MFC-8440 All-In-One Laser Printer

1 Answer

Black Streaks Everything I do (fax, print, copy) results in a paper with a solid black streak down the middle. The copier has been saying replace drum soon for one year, so I have learned to ignore that, but could that be the actual problem now? The streaks only started 3 days ago. It also now says toner low, but that started yesterday, two days after the streaks, and it has never done this before when low on toner. If the cartridges weren't so darned expensive, I would run right out and get one.. But the machine is about 5 years old and might be dying, so I'd hate to spend 100.00 to find out it won't fix the problem. Any help would be greatly appreciated.

Pull drum unit out and clean corona wire by sliding blue plastic tab from side to side, making sure you put the tab back on the side that it was. if that doesn't take care of problem, then i would say you need a new drum unit.

Hi, My Canon 3245 Imagerunner is streaking.


Hello,
First, the streaks appears when copy from glass or adf, when printing or all?

Solution #1:
How many copies did you do from last drum changing? if over 80 000 copies, replace the drum unit.
-in case that streaks appears when copy and print

Solution #2:
If the streaks appears only if you copy from adf or glass, clean the glass and dry it out. Both glasses, narrow on left side beneath the adf/cover and glass for copy of original.

Solution #3:
If the streaks are wide and solid, with possible toner left overs, you need to replace fixing film.

Hope that helps!

Printing black


Hello,
is the copy/print full black or have streaks or have dots, or ...

First, remove the toner crg., and check the drum surface if it has toner leftovers or spots or streaks, or... if so replace the toner crg.

btw. It also can be the fixing unit, but if these is the problem then the toner will not be "baked" on paper and it can be wide solid black stripe on corner.


Hope that helps!

My drum is at 40%. I have black vertical streaks


I was going crazy! Had a tech come in and look at the machine - needless to say he did NOTHING! A friend came over and was trying different things. It was that the "rack" that the toner cartridges sit in was not fully seated - once he pushed down a little and heard it "click" I had no more black streaks. AMAZING

Streaky copies


It probably has several issues - optics dirty, and drum, and blade failing. I would also imagine that even the Solid "blacks" aren't as black as they could be, and that would be the developer. This machine is in the 17 year old range, and I wouldn't spend dime on it
