After a jam my copier started to produce blank sheets. I replace the toner, but I still have the same problem. I check the copier for broken parts or jam paper, but it seems everything is in place. Did you have any other suggestion. Thank you

Hello, probably the problem is in laser shuter or toner cartridge pin in toner holder. But when you try to copy, when paper goes to the drum, open the right cover and produce paper jam, now look at drum for image, if on drum isnt image its laser problem...
If the laser shuter is faulty, these means that when you close the right door, the nose on door doesn't lift the laser shuter and so the laser unit cant write on drum.
If the toner crg. pin is faulty, when you insert toner in holder inside the copier, on right side of toner holder is small circle with pin that contacts the toner and gives voltage. You can apply some wd40 to that circle, that goes in and out when you open or close door.
But, probably is laser shuter... to check him you need to dismantle the copier.
On the new cartridge, did you remember to remove the plastic seal from the toner? Do you get blank sheets only when you print or when you make copies too? Were you careful when clearing the paper jam or could you have accidentally damaged the printer?
Please clean the drum and the fuser, also check the toner cartridges if there's any overflown toner powder spilled. The problem is caused when the toner waste tank in the drum is full or overflowing.
I have seen this issue before and your problem is likely due to very fine paper dust on the pickup rollers. This is easy to fix and takes only a few minutes. Use a soft piece of cloth (not a paper towel), a computer cleaning towelette or anything that does not produce lint; dampen it (unless your are using a towelette) slightly with cleaning alcohol and wipe off the paper pickup roller on all sides. You should also remove the toner cartridge and vacuum out the interior of your 4MP, use care if you are not used to poking around the interior of HP printers. You will usually find both white paper dust and maybe some black toner dust. Put the cartridge and paper tray back in place, print a couple of blank sheets as a test - you should be good to go.
A common mistake is that people think that the waste toner needs to be emptied and instead the toner needs to be replaced --- and vice versa. Check to make sure that the toner bottle is not empty. Also, if you made copies that took ( used ) more toner then the machine was able to replenish, the machine has not had a chance to catch up. Place a white sheet of paper on the platen glass and make blank white copies. You may only be able to get 1-2 copies at first but as the device catches up with the toner replenish you should be able to make more. The blank copies you make -- do NOT put that paper right back into the machine. Lay it flat and let it cool, this will help prevent unwanted jamming due to heat build up in the paper. IF you have good amount of new toner in the machine, gently tap the front line ( or rear line) that feeds the used toner into the waste bottle. Sometimes the waste toner will clog and back up into the machine giving false 'waste toner full' message.
THERE ARE TWO CORONA THAT PRODUCES BLANK COPIES, ONE IS IN THE DRUM UNIT ON TOP OF THE DRUM UNIT. THE OTHER IS IF YOU STAND IN FRONT OF THE COPIER OPEN THE COVER TO THE RIGHT, THERE IS A WIRE LOOKS LIKE A GUITAR STRING IF IT IS BROKEN OR MISSING, NEED TO REPLACE. GOOD LUCK
My printer is constantly getting jammed, spitting out blank sheets of paper in between every printed sheet, clicking and snapping, etc.
There are a few places to check for a jam - pull the paper drawer out and check there, take the toner cartridge out and you'll often find a sheet there that you cannot see from any other angle, open the little compartment at the back and check there and the usual paper sticking out of the output just enough to pull it out the rest of the way.
I'll be looking for a new printer this week though. I can't take the constant paper jams and sifting out the blank sheets when I'm printing 500+ statements a month.
Definitely NOT an office friendly machine!
