How do I clean the roller on this unit - rubbing alcohol and Q-tips? I consistently get large black streaks on my photocopy pages even though I have a new toner cartridge installed. A friend suggested that I might need to replace the unit if cleaning does not fix the problem.
Suggestions? Other things that I can do to try to fix this problem?
Thanks for your help!
Check your office supply store for printer cleaning paper. It is a heavier weight paper that is sticky on both sides. Run it through several tines to get paper dust off the rollers and paper path.

It sounds like excess toner has built up in or around the imaging drum. I would *carefully* remove the toner and drum (can be messy) and use some canned air to clean the inside out. If you are still getting these streaks, it might be time to get a new drum (DR 400) as you are supposed to replace the drum every 6 to 8 times you change the toner cartridge.

Hi Wooky,
The streaks are likely only present beside a bold character or heavy print section of the doccument content.
The print head assembly is likely carrying an obscure hair or piece of fluff back and forth which is acting like a paint brush.
The offending fibre is mos likely attached to the adge of the cartridge or print head carriage assembly. Also check the dervice station where the catridge docks when not printing as it can store fibres in the capping and wiping components especially if the printer is situated low to the ground where fibres tend to fly or you have fine haired pet like a cat, rabbit or toy dog.
Best way to clean is to trick the printer to unpark carriage (open top door to trigger carriage to present itself) then uplug power. Now you can move things at will to clean up with moist cotton buds (clean water is best).
Good luck

as i can suggest you that it can be the problem of head clogged internally where you insert your black cartridge .and the other main cause is while you give a head cleaning command to get the cartridge cleaned it sucks or pulls the ink from the cartridge in such a huge quantity that 3-4 cleanings make the cartridge totally empty .due to this the ink gets very low and the printouts come with streaks.many a times setting the print mode in best makes the copy perfect.but the printing gets too slow in that best mode.

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

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.
