Toner smudges along left side of documents. Have changed cartridges and cleaned everywhere I could reach but they remain

Go to the settinge. Go to maintenance a perform the cleaning steps.If that doesn't correct exchange cartridges . Remember recharged cartridges have problems. Possible you need to shake the cartridge.

It means your machine needs cleaning. You can purchase cleaning sheets from the office supply store, and insert it like a regular document, hit print, and the dirt comes off.

Hi:

This is a common problem with some HP printers. The fuser sleeve inside the fuser assembly gets torn along the edge and print can no longer be fused in that area and the paper will crinkle there. The only solution would be to replace the fuser, which for that printer it would not be worth repairing.

How do I clean white or black spots on printed documents? Description: First make 10 to 15 copies of a blank, white sheet of paper.
If you still see the spots on printed documents after making multiple copies, clean the drum unit as follows:

1. Remove the drum unit and toner cartridge assembly, and then remove the toner cartridge from the drum unit.
   
2. Position the print sample in front of the drum unit so you will know the exact position on the drum that is causing the poor print.
   

3. Turn the black gear on the drum as you check the surface of the OPC drum.
   The OPC drum is photosensitive so do not touch it with your fingers.
   

4. When you find the substance on the drum surface that matches the print sample, gently dab the surface of the OPC drum with a cotton swab that is lightly dampened with isopropyl alcohol.
   
Note
• Do not use a scrubbing or wiping motion because this might damage the drum.
  
• Do not try to clean the surface of the OPC drum with a sharp object, such as a ball-point pen, because this might cause permanent damage to the drum unit.
5. If the print quality still has not improved you need to install a new drum.
   

Hi! You may want to try head cleaning to resolve the blurry prints. The smudge may be caused by a full waste ink pad. Try to replace the wastepad and it may resolve the problem. Hope this helps and have a good one!

Open the top of the fax where your documents go in. There will be a thin **** of glass where the document is read. On the end that reads "dirty" is a smudge or some white-out that needs to be cleaned. You may have to clean it with some cloth wrapped on a flat tool. Do not scrap or scratch anything, just clean enough to get the dirt off. Then make a test copy.

Two parts of the printer can affect this.
1) the toner cartridge
2) the fuser

Testing can be done to determine the problematic part.

Do a print using manual feed. Once the last bit of paper goes into the machine, open the printer door.
Remove the toner to check if smudge is there.
Replace toner cartridge if there is smudge, replace fuser it not.

Try performing a test by printing a test page from Tray 1 and open the top cover as soon as the paper is 60% inside. The paper would jam below the toner cartridge before it reaches the fuser. Remove the toner cartridge carefully and verify if the smudges occur. This would eliminate the fuser. If the print quality is fine, then you need to swap the fuser.

Hi, try to pull out complete process unit(cartridge) with toner box .You have cleaner(blue or green color) move this cleaner from right to left side 4 or 5 times.Note that cleaner MUST be in home position-right side when you finish.Check print.
If problem still persists, you must do following:take away small grey plastic cap on left side of cartridge,then push complete charge corona(part with cleaner on top of it) to left side just enough to lift right side of corona from cartridge.Pull out that corona and you can see drum and developer roller. Turn the gear on drum,and look for smudges on black developer roller.Try to clean smudges with brush or with dry cloth.Toner will again attract to that area,but regular.

Pease check:
thet consumables is originals,
drum cartridge is not damaged
transfer belt is clean and not damaged.

you may have problem there, but if not you can try update firmware, maybe its a firmware problem.

first check consumables and if possible try changing them
