When replacing the toner cartridge, you MUST install a brand new, unused genuine Brother toner cartridge in order to reset the toner status. Swapping toner cartridges from one machine to another or installing a partially used toner cartridge may cause this problem. Brother machines control their image quality for the most suitable print quality by monitoring toner consumption. If you install a partially used toner cartridge, your Brother machine is unable to recognize toner consumption correctly which will cause this problem. Therefore, when you replace the toner cartridge, please use a brand new toner cartridge, not a partially used toner cartridge from another machine.

Bit of print at top then dirty streaks and no printing on rest of sheet

I know this is a silly question, but is toner cartridge full? Is the toner cartridge remanufactured? this sounds like a toner application problem. More info about the toner cartridge would help.

Keep it simple, but it could be a charge corona problem and it's arcing. If the inside of the machine is dirty with toner, get some canned air and blow out the interior of the machine. BE SURE THAT THE EQUIPMENT IS UNPLUGGED, and do the cleaning where it won't blow toner on your good clothes. doit outside or in the garage.

1. make sure cartridge has toner. If remanufactured, be suspicious. Especially, if toner is inside the machine. This indicates wrong/bad toner.
2. If tonered inside, carefully air blow the toner out. get another toner cartridge to try.
3. If problem persists, then a professional needs to do more cleaning and check voltages and clean electrical contacts.

I have a TallyGenicom 8008 color laser printer which while still printing well, is making a terrible noise - a grinding worn out part noise! Any ideas how fix it or lubricate it?!

I would suspect if the printer is still printing and feeding paper OK the problem may be related to one of the toner cartridges being stiff or partially seized.
From memory I believe the most likely toner to cause the problem is the black toner (or the yellow), but you can identify which toner is causing the problem by doing the following;;

  1. Open the front cover (the one you access the toner through) after a few seconds close the cover. The printer should go through a self test.
    If the printer makes a griding noise during this self test and warm up phase this helps with identifying the cause.
  2. Open the front cover again, this time remove the top toner cartridge
  3. Close the front cover with the top toner missing
  4. Listen for the noise heard in step 1, if no noise is heard it is likely the top toner needs to be replaced.
  5. If the noise is heard with the top toner removed, replace this in the printer and remove the second toner.
  6. Again close the front cover and listen or the noise, if it is heard the problem is with the second toner.
  7. Repeat this process for the third and fourth toners to see if one of these may be causing the problem.
After you have identified which toner may be causing the problem, you may wish to try gently tapping the cartridge.

An unorthodox method of solving the problem if you are feeling brave and don't mind sweeping up toner!!!!!!!! You may wish to drop the toner cartridge (GENTLY) from waist height to the ground.
This may dislodge any toner jamming the cartridge and will resolve the problem - It will also spill a bit of toner on the ground so you have been warned!

Recently changed the black toner cartridge in the Dell 3110cn printer. This past week when I print the entire page is being printed with a shade of gray. I think the toner cartridge has leaked toner and...

This could be a drum problem, the drum is part of the toner cartridge in this printer.

If the toner has leaked it will be all over the inside of the printer - you'll see it. I don't think that's the problem.

If the toner cartridge is an original Dell item, then it's likely to be replacable under warranty.

If the cartridge is a remanufactured item, it may be that the wrong toner has been used. Toner is NOT all the same, and this cartridge is one whe the wrong toner really will not work properly for long.

The chances are the changing the toner cartidge will cure the problem, provided you use an original Dell item, or a remanufactured item from a reputable manufacturer.

E020 Error message on NP6050

A E020 code is a toner amount problem in the developing ass'y. Is the copier asking for toner or was it and no toner was installed? If not the amount of toner is to low for the hopper to add enough toner in to over ride the toner sensor. Look in the developing ass'y for toner, if you only see about a 1/8' of toner you need to clean or replace the toner sensor. Then you are going to have to run in service mode " toner-s". Then rechk the amount of toner in the developer ass'y. It should be about a 1/2' or so. If not you have a problem with the toner hopper. And if that is the problem you may want to manually add toner in the developing ass'y to get the copier working again. You also have to clear the error code in service mode.
