Try printing from the manual feed tray(tray 1). Put a few sheets of paper in the tray. Print anything that is more than two or three sheets of paper. The paper path test is good, 10 sheets. As the paper gets about halfway into the printer, open the top door. Pull out the toner cartridge. Look down at the paper. If it's dirty it has to be the toner or the transfer roller. If it's clean it could be a dirty paper path or fuser.
Vacuum out the printer, if you have mounds of toner laying in the paper path, everything that comes out of the printer will be dirty.

While printing a document some ink dots are coming in every page of document


Did you replace the toner? dirty print out might be the sign of low toner or faulty drum unit.
But if the dots are repeating on same line..then most probably it's the drum or fuser problem.

Hp 4250 laser jet vertical streak ghost image


Hello,
The problem you are having is caused by the fuser. The fuser is the part in the printer that heats up and basically melts ( fuses) the toner to the page. The fuser has a heat roller that is coated with teflon, your fuser coating has worn off in spots so the toner is sticking to the roller and causing the ghost image. You will need to order a replacement fuser. You can do a search on Google to find a replacement, the parts number is RM1-1082.

I hope this helps, if so please rate our solution.

Black toner flakes on paper


Hi,
This could be a couple of things, easiest thing to try first is to put a different toner cartridge in, something that has already been opened because it would save you from opening a new one. Another thing you can try is sending a cleaning page through the printer to clean off excess toner from the fuser unit. What happens is over time toner builds up on the lower pressure roller of the fuser unit and after being heated and cooled so much the toner starts to flake off on your print outs. Follow these steps to try to clean the lower pressure roller:

To run the cleaning page manually
1.If a duplexer is installed, open the rear output bin.

2.Press check mark(SELECT button) or the MENU button to open the menus.

3.Use (UP ARROW button) or (DOWN ARROW button) to scroll to CONFIGURE DEVICE, and then press

4.Use or to scroll to PRINT QUALITY, and then press the check button

5.Use (UP ARROW button) or (DOWN ARROW button) to scroll to CREATE CLEANING PAGE for the(LJ 4200/4300) or PROCESS CLEANING PAGE if you printer is a(LJ 4250/4350) then press the check mark

6.Follow the instructions on the cleaning page to complete the cleaning process (LJ 4200/4300
only).

7.If a duplexer is installed, close the rear output bin.

This should help clear some of the flaking toner, if not you might have to replace the fuser unit.

HP LJ 2600 "dirty" printing


Hi,

If the toner cartridges are "refills" that might explain some of your print quality issues. Unfortunately, HP only has 2 replacement parts for that model, the fuser and the ETB (Transfer belt) both would require a technician to replace. Check the transfer belt of any tears or punctures. Careful not to touch it, oils from your skin can cause quality issues as well. If at all possible replace all the toners with ones that were working fine.

Ink smudges on the right side of the paper


Hi,

Your problem is due to a worn fuser unit (upper fuser roller).

The teflon coating has worn again, alowing the toner to stick to the roller and then "repeat" about 3x down the paper (getting fainter each time).

You need to order a new fuser unit.

Make sure you order the currect voltage (US or UK)

Images of previous page remains on the new printed page


It is either a bad drum in the toner cartridge or toner on the fuser. Try changing out the toner. If the problem remains, you'll have to get a new fuser module.

Hp 4250 GHOSTING


Are you telling the machine that paper type is letter head or envelopes, It must be done, it changes temp of fuser to suit the paper type, no it is not a power supply problem change paper type to card stock/thick/letterhead etc to suit then machine will adjust temp to suit.. ie file, print properties paper type.

50.2 fuser error replace fuser.
