Re: blank papers

Try again the old toner cartridge if you still have it. Even though the print quality might be bad, see if there is a printout. If the page is not blank like the others, that is an indication that the new cartridge is defective and has to be replaced.

Why won't it print test page?

If the test page placed face down on the glass does not contain text, you will get blank copies.

I have an HP 4515 that is printing blank pages. I have tried to replace the toner and the power supply board. Neither resolved the issue. When the paper gets deliver out the paper is warm. This occurs when...

I believe I understand your issue:-
The printer is able to come to ready- your still able to navigate the menus. the printer goes through all the motions of printing except producing an image-
Having the machine print a test page ( internal Print ) tests whether the formatter is still able to generate a digital image ready for the print engine, but does not diagnose the print engine-
1) power down and remove power cord
2)remove the toner cartridge, use a pair of pliers and gently rotate the drum ( within the toner cartridge, a drive gear/mesh can be found on the end of the toner unit)- are you able to turn this drum or has it seized?
if it doesnt replace the new toner with another NEW toner and try again
3) return the power and power up the machine having first disconnected all network connections.
allow the machine to come to ready.
4) ask the printer for a config page ( internal print) and estimate when the paper is immediately below the drum surface ( toner cart) and using the power switch turn the printer off- causing a jam in the centre of the printer - this is ok we do this to see if an image has been generated on the drum surface- remove the toner cartridge and slide the drum protector plate to the side, look carefully at the drum suface ( you should see a latent image of a config page, at this point look at the paper still jammed inside the printer and see if there are any signs of toner ( there should be part of an image allready on the surface ) now if there is an image on the drum but no image on the paper then I would replace the transfer roller and or transfer HVT power unit, if however there is no image on the drum then you have a very serious problem which will require a new laser unit ( but this should really come up with a diagnostic error code)or Primary HVT unit.

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.

My hp1012 is printing dark with shading on the pages and shadow or echos. Can something be replaced or fixed?

with this issue, you pretty much have to run a half way test unless you have the convieniance of another toner to try. basically, it's either going to br your toner or your fuser and a halfway test will determine this if you don't have another toner to try.

The Half-way Test

You will need to print a page and open the toner lid when you think the paper is underneath the toner cartridge. This will stop the printing so you can pull the toner cartridge out and look at the partially printed paper. It may take a few tries to time this test correctly so the paper stops under the toner but not completely into the fuser.
1. Print a test page from Tray 1, the "fold-down" Multi-Purpose tray on your printer.
2. Just as the test page completely disappears into the printer, open the toner lid door. The print job will stop, sensing an error.

3. Pull the toner cartridge out, and you will find the test page sitting directly underneath the toner.
4. Carefully remove the page by gently pulling the page upwards & free from the toner cavity. Careful! The toner has not yet been fused to the paper, so the print can be somewhat messy on your hands and may smudge easily.

Examine the printout.
1. If you do not see the print defect on your test page, that means the defect is being added later in the print process by the fuser. Fusers are the main component in a maintenance kit; click here to view our selection of maintenance kits for various LaserJet printers.
2. If the print defect is visible on this printout, that means the print defect is occurring before the fuser. Try replacing the toner cartridge (click here to view our selection of toner cartridges).
If you determine the print defect is occurring before the fuser, and swapping toners doesn’t fix the problem, there could be several things causing the problem. In the order of most likely to least likely: you could have two defective toner cartridges, the transfer roller might be faulty, the laser scanner could be dirty or defective, or the high voltage power supply could be bad. You might want to email or call since these scenarios are not as common.

Order Fuser Here!

Order Transfer Roller Here!

hope this helps and if so please mark FixYa!!

HP laserjet P2015 is printing blank

Are you getting toner on the paper? To find out, print a test page. When you judge that the paper is under the toner cartridge, turn the printer off and look at the toner cartridge. Is your document displayed on the toner drum in toner? Is there toner on the paper?

No No Replace the toner cartridge. If that doesn't work you have more serious problems.

Yes No Replace the transfer roller.

Yes Yes If toner is smeared on the paper, replace the fuser.

After cleared paper jam, HP LaserJet 1320 prints blank pages

Yes you can replace the transfer roller, but check to make sure the roller is firmly seated into its holder and that the springs are contacting the metal shaft.

Good Luck

My HP 1320 prints a thick black line down the left side of each page of a document.

Easiest step to do would be replace your toner.
Next Step is 1/2 self test page. This means start a print job and after the paper is picked up open the toner cartridge door and cause a jam. The paper that you see after you remove the toner will show the current print. If the mark is seen on the paper there then it is the toner cart. If you dont see it on the paper then it is most likely your fuser causing the issue.
