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.
An ink tank(s) is not seated properly. Paper is jammed or there is an object inside the printer. The encoder film/strip may need to be cleaned.
Whilst all printers will make a noise to some extent, the crown for the noisiest type of printer must go to the dot matrix printer.
The noise can be caused by any one of the following: A piece of paper is stuck on one of the rollers inside the printer. A roller in the toner cartridge is squeaking. A roller on a paper feed option is squeaking.
Powerful lasers do make sounds—but they`re not “pew” and they don`t come from the light itself. Instead, the noise comes from the equipment that generates the laser light or the interaction between a laser beam and an object.
When the bearings start to fail they tend to make a buzz sound. Then they stop working completely and your printer starts giving material movement issues as the extruders overheat. The easy way to test if it is a fan making the noise is to stop the fan turning briefly.
If your PC or the LCD screen on your printer is telling you that your ink cartridges are full but no ink is passing through to the paper, then it`s most likely that you are dealing with a clogged printhead. Blurry documents and images that appear faded are also signs that it`s time to remove the excess ink.
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.
There are a few things that could be the cause of this problem, including: Empty ink or toner cartridges that need replacing. Ink or toner cartridges that have become dislodged from their proper place. The wrong paper size loaded in the input tray.
It is perfectly safe to begin using Liquid Bearings on all your printers immediately, even if you have been lubricating them with conventional oils for years or decades. It is fully compatible with all vintage and current oils, and will eventually flush away the residue of the evaporated real oil over time.
There are different kinds of laser noise: In a single-frequency laser, there are intensity noise (or amplitude noise) and phase noise. The latter causes a finite laser linewidth, and is strongly related to frequency noise.
Laser Sound: Expectations and Reality

The most common level of sound produced by laser machines is around 75 decibels when in full operation and 10 to 20 fewer decibels than this when idling. To put this in perspective, a normal conversation happens in a range around 60 decibels.

The two biggest culprits for excess noise in computers are fans and the hard disk. Fans are used to move the heat produced by the processor, motherboard, and graphics card out of the computer. If the fans are loose, too small, or not powerful enough, they can create noise.
The most obvious is most common on laser color printers and can be detected by a flashing message on the printer display screen. Other signs of a bad printer drum include printing blank pages, printing gray pages and strange sounds coming from the printer as it prints.
Laser printers and copiers use toners. Toners emit harmful dust particles through combustion processes. An inkjet printer, on the other hand, uses liquid ink and does not emit fine dust.
When it isn`t working properly, the quality of your prints can suffer. Signs of a bad transfer roller include streaking, squealing, jamming and odors emanating from the printer. Troubleshoot your transfer rollers to restore your prints to their normal high quality.
Airborne particles within an office environment are a combination of particles generated from various sources, included are laser printers which emit paper fibres, organic vapours and inorganic gases. Research has shown that laser printers emit nanoparticles of substances, which could increase the effects of exposure.

Prints blank pages, won't print from computer
ANSWER : Don’t know why you replaced the fuser, but assuming you had print before, then it must have been something you did during the procedure. Only thing I can suggest is to recheck your work. Just because you reinstalled a connector doesn’t mean that it is seated firmly enough to work. Any flat ribbon connectors that you removed and reinstalled, check to see that the contacts are all flat and not peeled back.

Print file sent but no printing occurs
ANSWER : Been working on these since they first were released. Never seen a problem like yours. If it happens again, try doing an engine test, as it bypasses the formatter board. The engine test is located at the right side of the manual tray opening. Look for a hole in the side wall. Stick something like a paper clip into it to actuate the test button. It will then print a lined test page. If it does that, then it points to the formatter board as the cause of your problem.

Laserjet 4250 print quality issue (see image)
ANSWER : It looks like a fuser problem. One way to prove it is with the half-stop test. Put a sheet in the drop down manual feed tray. Send a print job and watch the paper. When the end of it is about to enter the printer, open the lid and take out the toner cartridge. Look at the printed image. If it looks OK, then it is a fuser problem. If not, then it is a toner cartridge issue since it hasn’t gone through the fuser.

My 2550n Color LaserJet does not want to print in color
ANSWER : That model had issues with the carousel solenoid sticking. That might explain why it works after you let it sit for 10 minutes. The solenoid gets hotter with use which causes the deteriorated foam on it to become sticky and hold down the release plate instead of letting it go. This allows the carousel to spin when it is supposed to stop for each color. The solenoid is located on the right side of the printer. If you open the lid, it is just behind the opening at the top right. You need to remove the top of the printer and scrape off the goo on top of the solenoid body. I put a piece of thin sticky backed felt to replace it. Other people use electrical tape.

HP Laserjet 1320tn printing grey instead of black
ANSWER : Try this test. Put a page into the manual feeder and do that same test. When the end of the page is just about to enter the printer, open the lid. Take out the toner cartridge and pull back the shutter. Look at the image and see if it is black. The explanation is that there is high voltage going to both the toner cartridge and the charge transfer roller below it. If the image on the drum is black, then the fault is at the transfer roller not getting enough high voltage. The transfer roller pulls the image off of the drum and down onto the paper. It would not be a laser scanner problem as any issue with it would not result in an overall gray image, but combination of gray and black. It will probably turn out to be a bad HV power supply, which will need replacement. I’ve never seen this particular problem on this model.
