Your drum rollers may be going bad (grinding noise) which will sometimes cause the drum to drop slightly, creating a gap where the clothes get caught as the drum rotates. (black streaks)

Drum is dirty from main barring leaking. This is job to fix by professional

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!

I have the same problem and read somewhere to replace the felt belts. We have done this twice and still getting the brown marks. I have found using Goo Gone and/or Dawn dish soap and scrubbing with a brush will take most of the mark out, re-wash and HANG to dry. I'm still looking for a permanent solution to this problem, as much as these dryer cost and you can't dry white clothes???

You will have to have the dryer drum felts replaced. It requires removing the drum from the dryer so you may want to have a technician do this because removing the belt can be tricky.

ck rear (or front if it has one)drum seals they tend to develop rust stains over time the rust comes off on clothes leaving brown streaks ..seals will need to be replaced although you may try a bleach and water solution first drum will need to be removed to replace seals

REPLACE DRUM CARTRIDGE THE CLEANER BLADE IS BAD

To all victims of the brownish colored streak marks: I share your frustration!!! I have the same problem with my dryer which started when my dryer was only 3 or 4 years old - - totally unacceptable for an expensive top of the line dryer! A repair guy showed me how the brownish streak marks come from the felt liner which goes around the drum. Look inside your dryer for the beige or tan colored felt which sticks out around the circular drum. If you rub the felt with an old white t-shirt or paper towel, you will see the same brownish colored marks. My repairman recommended getting the felt replaced eventually, but until then, he gave me the following tips which really help avoid getting the streaks: For white or light colored clothes susceptible to the brownish streak marks: I dry these items as part of a very lightweight dryer load - with just a few other lightweight items. By doing a small lightweight load, clothing is less likely to get caught up & rub against the felt edges. For example, I dry 4 light colored men's dress shirts with 2 or 3 other lightweight shirts. OR for white or light colored athletic "dry fit" type athletic apparel, I dry 6 - 8 total lightweight shirts/shorts. If I throw my white Nike top or white pair of summer pants into the dryer with all my "whites", they will be doomed to getting brownish streaks due to the heavy load pushing them against the darned felt liner! Whenever possible, I wash susceptible items on permanent press to avoid wrinkling, then hang dry. Prior to putting these clothes in the dryer, I also "pre-clean" the felt with an old white cotton t-shirt by reaching into the dryer and rubbing along the felt edges until I'm not getting as much brownish color on the t-shirt rag. For a permanent fix, call a repairman or see the following do-it-yourself YouTube video on "Dryer Repair - Replacing the Lower Front Drum Felt Seal": http://www.youtube.com/watch?v=XoYP_YsGP68 . I have a repair person coming today to fix 2 other appliances, so I'm finally getting my dryer fixed, and I will post an update soon.
