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,

I have a Kyocera CS-2050 and there is a dark line that prints in the center of the pages. What causes this and how do I correct it?

Several things can cause this if it does this when copies are made on the doc feeder try making copies on the platen glass (the main glass). If the copies on the platen don't have the line its the **** glass the small line of glass left of the main platen glass. Clean with windex or alcohol. If it does it when any copies are made and doesn't do it when prints are sent from the computer Than the optics (mirrors) need to be cleaned. If it does it from prints from the computer than it might be the charge wire. To clean this open the front door and next to the waste toner bottle their is a slim green tab. Pull it out until it stops do this several time. If that doesn't fix it it might be the drum look for a line in the drum hold the page next to the drum to see if the line lines up with a deeper impression in the drum. Maybe the fuser unit do the same with the fuser (the unit that gets hot) and see if the teflon is worn off (will be a gray line were it has worn off.
If you have anymore questions just ask.
Hope this helps.

Have you cleaned the optic's? what roller was replaced? Was it the drum unit? If not you may need to replace the drum unit.

Sharp AR-M280N- Printing dark lines

It sounds like you are going to need a new drum and drum cleaning blade. How long has it been acting up? When was the drum last replaced? The image repeatting could also be coming from the UFR??? It really depends on how many copies you have on it and has it been seatting for awhile..... Need some more info... But you most likely will not be able to fix your self..
