Re: monroe 946 copier

The drum cleaning blade is located in the drum unit and is very much like a windshield wiper blade on your car and even has the same function. It cleans the drum of toner residue after each copy is made. A positive test to see if the drum blade is worn is to make two or three copies of an original and if the streaks are worse on the second copy and worse still on the third copy, then you can be fairly certain that your drum blade is bad and needs changing. Not a simple task, probably best left to a technician. You can do some serious damage to the drum if you're not careful. If the test that I described indicated that the drum blade isn't bad, then the next most common problem is a worn heat roller in the fuser. Not an easy thing to replace either. You can check this by making a copy and stop the machine just as the copy just reaches the exit rollers of the machine. After removing the copy, you can see that part of the copy has been through the fuser, the part of the machine that gets hot, and part has not reached the fuser. If the lines are on the copy that has passed through the fuser, but aren't there on the part of the copy that hasn't reached the fuser, then you can be sure that the lines are caused by the fuser roller.

Let me know if this helps.

Kyocera Mita 2050 there are streaks of toner appearing on the pages printed.

If you send a print job or print a report from the copier and there is no streaks then the problem is most likely the thin **** glass to the left of the large glass. It just needs to be claened.

If the streaks are happening when printing and copying then the problem is most likely your drum unit (MK-410) or possibly the fixing unit (FU-410), the fixing unit is the one that gets hot.

As the drum gets old it can cause print/copy issues and the cleaning blade that cleans the drum gets to the point it doesn't clean the drum properly causing streaks.

The heat roller has a teflon coating on it and as the roller gets older the teflon starts to come off and can effect prints/copies.

The drum unit should be replaced every 150,000 pages and the fixing unit every 300,000 pages on the KM-2050.

I hope this is helpful,

My minolta ep 4000 copier prints with thick black streaks imprinted on page. what's wrong? is it the corona, the drum, or something else?

Most likely it is the drum cleaning blade. One indicator of the drum cleaning blade going bad is that the black lines will get worse as you run multiple copies. So if you make 10 copies for example, the last copy out will be streaked worse than the first copy out. Drum cleanig blades are about $30 bucks plus whatever your local service guy charges for a svc call.
Good Luck and Thank You for using Fixya.

Konica di620 ghosting and streaking

What about the starter/developer last time its been changed? Upper fuser/fixing roller (Hot rollers) don't forget to clear counters once those parts are installed.

Black blotches and streaks on copies

Sounds like a worn drum unit primarily the cleaning blade on the drum is failing. If you don't change it out soon the dirt escaping from the drum and dirty copies will foul-out you fixing unit, = more $$.

It prints vertical lines where the text is.

check your drum unit. The toner cartridge mounts into the drum which can be permanently charged causing a constant streak to occur.

Remove the toner and drum unit. Clean them off with a non-fuzzy non-rough cloth or paper towel. Pay particular attention to where the streaks are in relation to the toner cartridge and drum. If you clean it off and you still get streaks check whether they transfer from the toner or just from the drum.

There may be a way to discharge the drum, otherwise you need a new drum.
