L have an HP2420 with the usual line down the left side 1.5 inches from the edge. I cleaned whatever I could see and it is less but still a faint line. We don't have high volume, use only HP cartridges...

Run a "half test". Put paper in the manual feed tray(tray 1). Print anything. Watch the paper. When it gets about 1/2 way into the printer, open the top cover. Remove the toner. Look down at the paper. Do you see the "usual" line? If yes, replace the toner cartridge. If no the fuser is probably bad.

My HP 2420 had a paper jam. I played around with it and must have cleared the path although I did not see any paper particles fall out. (I did have a jam and figured a small piece must have been left...

Check the following steps for fixing Hp Carriage Jam Error :

Open the print carriage access door. Check for any packing material that may be blocking the internal components. Check for an orange shipping lock that may still be in place on the left side. Pull the shipping lock out, if present, and discard.

Remove and reinstall the cartridges to make sure they are properly installed. Lift the front center of the print carriage access door to open it. Lift the door up until it locks into an open position. Press down on a print cartridge and allow it to spring back up. Lift the cartridge out of the printer. Do the same for the other cartridge. Slide the black cartridge into the slot on the left and the color cartridge into the slot on the right. Press down on each one to lock it into place. Lower the print carriage access door.

Check the print cartridges to make sure the protective tape has been removed from the ink nozzles. Remove the cartridges from the printer. Remove any tape or labels. Replace the cartridges into the printer.

Push in on the tab on the left side of the clean-out door on the back of the printer to open the door. Lift the door out of the printer. Check for any paper jams. Jammed paper can block the printer cartridge carriage from moving. Pull any jammed paper out.

HP 2840 will not print on 3 inches of left side of page

Take the toner cartridge out, shake it back and forth, and turn it around in a circle a few time. Put it back in the priter, and print. Order a new toner cartridge.

If this is an inkjet printer, ignore this response.

HP Laserjet 2420 is printing a vertical black streak along left side of page.

This is either a defect in the cartridge. Or a defect i the fusing unit. Try a different cartridge to see if it goes away. Most all print quality issues on HP's are from the cartridge. If the cartridge does not fix the problem then the fuser film is goin bad. You can replace the fusing unit or find a local guy that can do just the film. Much cheaper. If the line down the side kind of "rubs" off like the toner is loose on the page then it is definately the film.

Light grey vertical line printing on left side of paper used the cleaning cycle and line in now doubled There is a black vertical line down left side of the page. I used the cleaning page but the line is...

Hi there,

I believe there are 3 possible causes for this issue; toner drum, fuser or transfer roller - more than likely I would dismantle the printer and check for lines on the fuser. But just in case remove the toner and carefully release the flap to reveal the toner drum - if that is scored and the lines correspond to those on the print-out thats the cause.

Hp 2420 vrtical line in page


This issue can be due to fuser. I am sure you have changed the toner cartridge.
To confirm its a fuser issue, please perform the following:
1. Try printing a configuration page from tray 1, pull the top cover, as soon as the media is 60-70% inside the printer.
This would stop the paper before reaching the fusing assy.
2. Remove the paper and check if the line exist.
If exists, fuser is not faulty.
If it does not, then transfer roller, laser/scanner assy is faulty

- If fuser is faulty, perform the cleaning page as following
1. go to configure device > print quality > create/process cleaning page
perform cleaning page 5-6 times, however, if the line is due to fuser, then fuser needs to be changed.

Let me know the next update.

Horizontal black lines across page.

Horizontal lines usually indicate a toner cartridge that is not cleaning properly.

A. If the distance between defects is 38 mm (1.5 inches), 47 mm (1.85 inches), or 94 mm (3.7 inches), the print cartridge might need to be replaced.
B. Clean the printer.

1. Clean the inside of the printer and run a cleaning page to clean the fuser.

Over time, particles of toner and paper accumulate inside the printer. This can cause print-quality problems during printing. Cleaning the printer eliminates or reduces these problems.

To clean the inside of the printer
1. Turn the printer off and unplug the power cord.
2. Open the top cover.
3. Remove the print cartridge.
4. With a dry, lint-free cloth, wipe any residue from the paper path area and the print cartridge
5. Reinstall the print cartridge and close the top cover.
6. Plug in the power cable and turn the printer on.

Cleaning the fuser:

Run the printer cleaning page to keep the fuser free of toner and paper particles that can sometimes accumulate. Accumulation of toner and particles can cause specks to appear on the front or back side of your print jobs. To ensure optimum print quality, HP recommends that you use the cleaning page every time that you
replace the print cartridge or on an automatic interval that you can set up. The cleaning procedure takes about 2.5 minutes to complete. A CLEANING message appears on the printer control panel display while the cleaning is taking place.
To run the cleaning page:

In order for the cleaning page to work correctly, print the page on copier-grade paper (not bond, heavy, or rough paper).
1. If your printer model includes a duplexer, open the rear output bin.
2. Press Menu to open the menus.
3. Use (Up button) or (Down button) to scroll to CONFIGURE DEVICE, and then press (Select button).
4. Use (Up button) or (Down button) to scroll to PRINT QUALITY, and then press (Select button).
5. Use (Up button) or (Down button) to scroll to CREATE CLEANING PAGE, and then press (Select button).
6. Follow the instructions on the cleaning page to complete the cleaning process.
7. If your printer model includes a duplexer, close the rear output bin.

If this helps resolve the problem, please post a reply. Binary Bob

Print quality problem

Hi there sound to me like the toner cartridge is either faulty or leaking. Is it or has it been refilled if so remove cartridge vacuum out the insides of loose toner install brand new toner cartridge then test again. It cannot be the fuser unit as it will have quality problems all the time so try above and I hope it works for you.

Thanks J
