SOURCE: Have just placed new toner cartridge., prints have black stripes

Try cleaning the charger wire on top of the toner/drum unit. It should have a green plastic knob/handle to slide the cleaner left to right and back. Do this several times.

SOURCE: black streaks

This is caused by a rotating part that is contaminated, most likely the drum that transfers the toner to paper.

A new drum or drum cartridge is probably needed.

There is a very remote chance that the high voltage that charges the drum is being modulated but I have seen this once in decades of service.

Black tinting or scumming on pages


HP has a cleaning page that can be created to help remove toner build up on the fuser roller and I believe one for the drum also. Print "Menu Map" to find the cleaning page quickly. These are the two areas that need to be cleaned to help eliminate the "scumming". I would also look inside the device after removing the print/toner cartridge and if you have the toner wipes, remove any toner spillage inside. please do not use paper towels as they shred too easily and will mess up the transfer roller.

Unable to remove black cartridge, it is really stuck. Help


I just changed my black toner this past week, and finally figured out why the cartridges get stuck like this.

First, you must eject the toner cartridge on the front-panel menu:
Menu->Replace Toner->Eject Toner->Black(K)

It will say "Rotating to Black Toner(K)" and then say "Black Toner(K) Ready to Eject"

Now, open the front panel and you'll see the black toner cartridge in front. You can also open the top panel if you want more light on your work area.

Lift the lock handle on the old toner cartridge to the "unlock" position, and here's the part that the Dell instructions don't have:

There are two channels for the toner cartridges -- one on each side. Run your finger down the channel on the right, and you'll feel a small, spring-loaded catch. This catch often gets sticky and won't release the cartridge without some help. Don't force it, but gently move it towards the back of the printer and it should release.

Now the old cartrdige should slide right out, and you can finish per the instructions that came with the new cartridge.

After changing toner on my sharp, SF-2022 copy machine, the copies are coming out with black smudge marks across the paper? how/where should i clean?


This means the machine is over-toning ie using more toner than required caused by either improper toner or different brand of toner. The correct toner is sf 222T1. Replace developer and use the right toner and clean the drum and its blade. You may need to clean fuser rollers for cleaner copies.

Printing black line when coping


You may need to replace the toner cartridge or the fuser assembly.

If you open the toner cartridge door and see a black line on the roller, you will need to replace the cartridge.

OKI Laser Printer C5300 printing on paper with black flecks


IF you are using after market black toner then we found your problem. Putting a real toner on now wont help cause dodgy toner is now in the drum, you need to replace Black drum and use real toner. If you are using gen OKI toner, then just replace the Black (K) drum.

Clean led head and these printers dont need a teco, they are designed for wearing parts to replaced by operator ie Transfer belt, fuser, drums and toners.

Printed pages look dirty


That black dust that fell out is the toner. When you shake a toner cartridge that shouldn't happen. It looks like you have a faulty toner cartidge and that need to be replaced! Now to make your printer prints cleanly and clearly after you replace the cartridge, you'll need to get someone to service the printer(the faulty toner cartridge more than likely spilled toner on your internal printer parts, cause the smudges). Sevicing would mainly entail, taking down the printer and removing any spilt toner! If you feel you are up to this, be cautious, because toner can be hazardous to your health if you accidentally breathe it in! hope this was helpful! regards babb
