This noise can be due to any one of the following: A piece of paper, or other obstruction, is stuck somewhere inside the printer. One of the toner cartridges or photo developer units may be installed incorrectly or may be damaged. A door or cover may not be closed completely.
A grinding sound is heard when the printer is turned on or when it is printing. Blinking lights may accompany the noise. The problem can be caused by a carriage stall or a paper jam.
A clicking sound may occur if the stirring spring assembly inside the Toner Cartridge catches on a rib within the cartridge, preventing the stirring spring and its gear from turning. The resulting click is caused by the drum`s toner drive gear slipping against the stirring spring gear on the Toner Cartridge.

After replacing the fuser you may hear a rumbling sound from the rear side of the printer. This rumbling, or grinding, is due to the newly replaced gears working with the worn fuser drive gears.

When a computer fan spins loudly for a long period of time, there might be an issue with a fan, or the computer might be overheating. Adjust the power settings, clean the fan vents, check for suspicious processes, and then update the BIOS to help reduce the internal temperature.
There are many reasons why a laptop fan may be making noise, including overheating, lack of cleanliness, hardware issues, or software issues.
You`ll know the drum is dirty if you notice that the print quality has become blurry and features blank spots or oddly-colored spots despite having full toner cartridges. Horizontal lines across the printout when the paper passes over a dirty area are another sign that it`s time for some maintenance.
The noise you are describing could be the carriage sticking or a small piece of debris inside the unit. You could go thought each of these documents step by step to clean out your printer to see if it resolves the issue.
Laser printers are almost always louder than ink printers because they have many more parts in operation at the same time. Even though many of these parts aren`t themselves particularly noisy, the fact that all of them are moving all the time can contribute to a few headaches.
That grinding noise means something is loose inside the hard drive, where there simply shouldn`t be anything loose at all. That typically means that when that thing becomes completely loose, it`s going to go flying around in there and cause all sorts of destruction within the drive itself.
The reason varies for inkjet printers and laser printers. In case of the inkjet printers, the noise occurs due to the ink cartridge alignment and for the carriage to move to the side of the printer. up of the fuser and certain internal process occurs.
If your computer is making a grinding noise, it could be caused by a failing hard drive. If the noise is coming from the fan, it could be because the fan is dirty or needs to be replaced. If you hear grinding from the speakers, it could be due to a problem with the sound card.
Paper pushed too far into the input tray when it is loaded, might feed into the printer incorrectly, causing the paper to tear. Paper stacks loaded into the input tray with too many or too few sheets of paper, might feed into the printer incorrectly, causing the paper to tear.

What repair needs to be done for a "50 needs repair" message on an HP Laserjet IIIP?
ANSWER : I don’t know what you mean by good toner cartridges. They haven’t been built in about 10 years, so if they are new OEMs in the box, they are guaranteed to fail. The 50 error on that printer is mostly a burned out fuser lamp. This site was sold, so as you can see, there are no more kits available.
