put paper in the upper slot (known as the MP), pull all paper from lower tray, send document to print and see if it prints ok - if it does, the problem may be with the lower print drawer - there is a spring under metal pad that lifts paper so it's grabbed by the printer paper transport. the spring may have broken or become dislodged so separation pad (the metal plate holding paper up) remains down - the transport "thinks" there is no paper
Make sure that the paper guides in your paper tray are not holding the paper too tight against the front of the tray, there should be about 1/16 inch play so that the paper can be lifted to the roller easily. Also take out your toner and drum and turn it on, if the grinding noise is gone you may need a new toner, some refilled toners are too tight to turn properly.
Remove any paper trays. Inspect them for wrinkled or damaged paper.
Also open the back cover of the printer if this model has one.
Open any other doors that give access to the printer's paper path and to the toner or ink cartridge.
If necessary, remove the toner or ink cartridge. Place it away from light/ sun light to avoid damaging it.
If you find a piece of jammed paper, remove it by holding it with both hands and pulling firmly. The goal is to keep the paper from tearing. If several pieces are jammed together, try pulling out the middle piece first to loosen the jam.
If the paper does tear, try rotating the roller gears manually to free the paper. Don't force anything, though. Do this step especially if the jam message comes up repeatedly without any obvious paper jam, there may be a small tear of paper inside.
Ones the printer is free of paper Replace the toner or ink cartridge and paper trays, close any doors you opened and turn the printer back on.
If the printer paper jam message still appears, then there is still some paper in the printer. Reinspect the paper path.
see alternative if the problem is still not solved.
alternative : Load a piece of thick paper, for example photo paper and press the resume button (may be diffrent button on diffrent models) a few times to the printer picks up the paper and puts it through the machine.
NOTE: Refer to the Testing section in this document for instructions on performing the tests.
Turn the printer off, and then turn the printer on. The grinding or squeaking noise should not occur while the printer is initializing.
Perform a paper path test. The grinding or squeaking noise should not occur because the carriage should not be moving.
Perform a self-test to localize the noise.
Check the printer for obstructions by lifting the top cover and making sure nothing is blocking the carriage movement.
Check the paper path by following the instructions below:
Remove all media from Trays 1, 2, and 3.
Pull out any visible stuck paper.
Lift the top cover, and pull out any jammed paper.
If you are unable to free the jammed paper, pull out the handle of the paper knob, pull the knob away from the printer, and rotate it to remove the paper.
Lower the rear access door by lifting up on the two rear door latches.
Remove the back panel by pushing the two catches inward.
Pull out any paper that may be stuck inside.
Wipe down the milky white strip (see Figure 1) that the front of the carriage glides on with a clean, soft, dry, lint-free cloth.
Figure 1: Location of the white strip Replace the whole unitIf the printer is still making a grinding or squeaking noise after following the steps above, replace the whole unit. See Whole Unit Replacement instructions, which are included with the whole unit replacement. TestingUpon replacement of the whole unit, perform a Paper Path test and a self-test as described below to verify that the new unit is functional.
Performing a paper path test
Press the MENU button on the printer control panel until Diagnostics Menu is selected.
Press ITEM until Perform Tray x Paper Path Test is selected.
Press SELECT to perform the test.
NOTE: The paper path test will terminate only when the paper in the tray being tested runs out or the printer is turned off. Performing the stand-alone self-test
Press the MENU button on the printer control panel until Self Test Menu is selected.
Press ITEM until Print Menu Map is selected.
Press SELECT to perform the stand-alone self-test.

purchase a maintenance kit.
replace the piper pickup roller.
since the the printer is old and lots things need to be replaced. it is easier to replace all of the necessary parts when you have the printer apart.
the job is not difficult, just time consuming.
If the HP LaserJet series printer is experiencing a grinding or odd noise when printing or on power-up, open the printer and remove the print cartridge. Close the printer door. If the noise does not recur with the print cartridge removed, replace the print cartridge. If the noise persists, this may indicate a hardware failure. If possible, isolate and identify the location of the noise and contact a local HP sales and service ofice at the number noted in the product User's Guide . A list of phone numbers can be found at
I took mine apart from the back and put it back together and it worked. It is probably due to moving it and the bottom paper tray alignment gets out of whack. I inspected all of the gear train and didn't find any worn or missing teeth. I suspect a paper jam started it and the user turned the printer around to open the back door. Since the handles are on the printer the tray doesn't move with it which allows it to separate and possibly jam a pickup drive gear.
