If a small piece of paper or other item wraps around a roller, it can cause a squeaking noise to occur. Check the condition of the toner cartridge. If the cartridge appears fine, reinsert it into the printer. If the cartridge appears damaged in any way, try installing a different toner cartridge.
Turn the printer on, and replace the cartridges if possible. If the carriage moves, but there is still a grinding noise, there may be a paper feed issue. If the carriage will not move, then it is a carriage stall issue.
Excessive dust on the main pick-up roller will make it appear worn and smooth to the touch, causing the roller to skip across the page instead of grabbing properly, resulting in blurring images. Excessive dust on the rest of feed rollers in the scanner will make a squeaking sound as it feeds the paper through.
This could be because of dust particles in the printer. Follow these steps to clean the ADF`s pick rollers and separator pad. Gather the following materials: A clean, lint-free cloth, or any cloth that will not come apart or leave fibers.
Paper curl is caused by an excess amount of moisture in the paper. The first step to ensure less paper curl is to store your paper in a cool, dry area. By doing so, you will reduce the amount of moisture and humidity the paper is exposed to. The next step is to always fan the paper before placing in the machine.
Also, impact printers have very high noise levels because they have several moving parts and also the printing head strikes on ribbon and paper. The quality of print produced by an impact printer is very poor than that of a non-impact printer.
Your printer`s IP address is the 12-digit ID number and is used to connect the printer to the internet or to another device. If your printer has a problem, knowing your printer`s IP address can help you fix it faster.
Find the printer IP address. HP Smart app (Windows, Mac): Open the app, click your printer, and then click the Printer Settings tile to find the IP address. HP Smart app (Android, iOS): Open the app, tap your printer, and then tap Printer Information or Network Information to find the IP address.
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.
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.
The printer may be set up to use Quiet Print Mode. The engine speed gets reduced in this mode and it can make the printer whistle like this. If you know it`s own or aren`t sure, turning it off may get rid of it if it annoys you that much.
The sound is normally caused by the plastic components of the controller having slight imperfections which can cause the parts to rub/catch on each other.

A grinding noise when using the scanner glass or flatbed to make a copy or scan a document is typically due to a mechanical malfunction of the scanner assembly. However, it may be the result of debris or objects interfering with the travel of the print head.
