Streaks through printing w/black toner

Are the streaks horisontal or vertical on the page?
What printer? Laser or InkJet?
If laser, and streaks are vertical, you might have some dirt stuck in teh tomer cartradge or somewhere along the paper path
If laser, and streraks are horisontal, your toner cartridge might be dirty or leaking toner

This is a common problem with a close-to-empty cart.

A new cartridge will have even toner, and will distribute it evenly to the page.

An older toner will start to streak and line onto the page.

Another issue could be the fuser... some of the new printers have a fuser built into the cart unit... so that when you replace the cartridge it replaces the fuser as well.

A fuser can become dirty and thus not distribute toner evenly across the page.

Cheers!

I have the same streaks problem. Any solutions?

Had a similar problem. Tried lost of things. In my case, the streaks cleared up after I cleaned the toner drum.

Take the cartridge out and shack it side to side a few times to move the toner around and reinstall it.

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

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.

Hey Chuck, Any chance you can post a scan of one of the faulty pages ? This will make it easier to assess the fault. Print off about 10 pages of a page that is affected by the lines. Look at each page and see if you can detect a recurring pattern over any of the pages. If there is a pattern, chances are it is probably the PCU that is marked.

you will have to check the Minolta web tech support team for this one.

Without actually seeing a print sample or the machine, my bet would be on the black print cartridge. Even though it reads a an acceptable level of toner, the cartridge itself sounds like it has developed a proble. 1. It's the most obvious 2. It't the cheapest place to start. If it does not correct the problem, you can still use it later. 3. It's the problem in about 80% of these types of cases. 4. I know it should be fine, but if things didn't go wrong, I wouldn't have a job! Let me know. If not we'll investigate further. Ed
