HP 2420dn printing gray and shadows

Our office uses the HP 2420dn for several users. We recently replaced the toner cartridge and it is now printing shadows. We tried to run a cleaning and that made it worse by causing it to print pages dark gray. Please help!

    We have the same problem...It just started a few weeks ago, right after we changed the print cartridge.

Just installed a new cartridge for the 2420dn printer and it is printing very very light, or not at all.


Some of these cartridges ship with a pull strip that keeps the toner from running out during shipping. Remove the cartridge and check on both sides to see if there is anything hanging out. If not, the cartridge might have a bad PCR. If the printer worked before putting the new cartridge in, it is likely the cartridge that has a problem and any reputable vendor should replace it. If you still have the old cartridge, try printing with it again.

HP Laserjet 5P shading edges of page


This is probably due to a defective cartridge, Charge Roller or Transfer roller.

Check the cartridge for a band of toner still on the drum.

Check the Charge roller for oil or smudges, this roller should be a lighter color and should be relatively free of toner or marks.

Same as the Transfer Roll, which will be dark, though excess toner should be evident.

A relatively smooth straight line is generally the cartridge.

A rather wavey or broken line is most likely the rollers.

You can however attempt to print a large amount of pages (25-50) in an attempt to clean the parts, however if either part is defective they will need to be replaced and no manner of printing will clean them.

Shadowing/graying with printing


Hi fa1103:
Gray background
1. Do not use media that has already been run through the printer.
2. Try using a different type of media.
3. Print a few more pages to see if the problem corrects itself.
4. Turn over the stack of media in the tray. Also, try rotating the stack 180°.
5. Open the Configure Device menu at the printer control panel. On the Print Quality
submenu, increase the TONER DENSITY setting. See the user guide.
6. Make sure that the environmental specifications for the printer are being met.
try these steps to see if they work for you.

Getting extra characters printed on paper from previous run


Asside from removing the toner cartridge and using a lint-free cloth or tissue to remove toner residue (or possibly using a can of compressed air to blow it out) there isn't much to be done to clean it. If you are getting ghosted images from a prevous page, your toner cartridge may be defective.

If you are using a refurbished or re-manufactured toner cartridge this would not surprise me. The only remanufactured toner company my clients have had any success with is Rhinotek, but i recommend sticking with the HP cartridge. Also if it is an older cartridge and infreaquently used it may still need to be replaced. If replacing the toner doesn't fix the problem after several test prints, then it is possible that the fuser is bad... in which case it's time for a new printer since the fuser is not replaceable.

Poor print quality


After you have printed a page remove the toner cartridge and look at the drum underneath, is there a ghost image of what has just been printed on it?? if so the cleaning blade is faulty and you'll need to replace the toner cartridge - this is the most likely cause of your problem.
Your printer does have a fuser and it can be replaced, but i don't think it's the problem.
