HP GRINDING WHEN TURNED ON OR PRINTING
A GRINDING NOISE MAY ALSO BE ACCOMPANIED BY BLINKING LIGHTS. THIS IS USUALLY A SIGN OF EITHER A PAPER JAM OR A CARRIAGE STALL.
HP Grinding, Squeaking, or Screeching During Printing
This painful sound is a plea from your HP printer to please clean it. This can be accomplished by gathering...
a cotton swab, cloth, or some other lint free material,
distilled water (tap water may contain contaminants that can damage the cartridge),
a clean sheet of paper.

HP CLICKING OR CRACKING NOISE
This could also be a sign of a paper jam that will prevent paper from actually loading into the feeder. First, disconnect the printer from the computer and then the power. After turning the power back on if there is still a noise, take paper out of the printer tray and look inside the slot for any dislodged or jammed paper. If there is nothing present, try feeding the paper through the printer. If this does not work, the printer most likely has a mechanical problem with the feeder assembly that needs to be repaired.
LEXMARK GRINDING OR SQUEAKING
A Lexmark printer has few parts that would cause it to make a squeaking or grinding noise.A grinding noise will usually be a problem of a loose gear or roller in the printer. Other problems could be rear exit rollers or gears, loose or broken parts, or small pieces of paper that have become jammed in the printer.
If the sound started shortly after a new toner cartridge was placed in the printer, remove it and check to see if the charge roller and transfer roller are seated inside the printer properly. If the sound persists after the toner is re-installed, it might need to be replaced all together. However, there is a small chance that the problem is because of the toner cartridge.
LEXMARK THUMPING SOUND
A thumping sound is a side-effect of a feature called Envelope Enhance. This is built in to the fuser unit of the printer to help keep envelopes fro wrinkling. This sound is actually nothing to worry about if the printer is printing on envelopes.
If you are not printing on envelopes or from a front-loading feeder or if your printer does not have the Envelope Enhance feature check the paper size setting on that front loading feeder as follows:
- Press Menu > to enter Menus.
- Continue to press Menu > until you see PAPER MENU.
- Press Select to view the list of menu items for the PAPER MENU. The second line should read Paper Source
