Consistent Squeaking Noise

Ck all units that run against the belt, something is probably locked up and causing the belt to squeak.

Washing machines don't usually run silently, but in most cases, a squeaking noise that occurs while the washer is agitating the clothing is not normal and signifies a problem. If the noise only happens when the washing is agitating, the problem is likely connected to the motor or your water pressure. Depending on the specific cause, you may feel comfortable fixing it yourself. Otherwise, call a professional.

The Agitator

• Agitators are located in the center of the drum, or basket, of top-load washing machines. Front loading washing machines do not use agitators -- instead, gravity moves the clothes from the top of the drum to the bottom. Agitators usually consist of a tall cone fitted with arms at the base. The purpose of the agitator is to rotate the clothes and soapy water around the tub to clean the clothes. The agitator itself is not usually the cause of the squeaking noise. It is powered by the drive mechanism, which consists of a motor, clutch and gears.

Motor Problems

• A repetitive squeaking noise during the agitation cycle may signify a problem with the motor. Specifically, the belt on the motor may be wearing out. Some motors use rubber couplers, which also wear out easily. The belt is necessary for the agitator to turn, but over time, it wears thin, just like the belts in your car's motor. An easy way to test for this problem -- if you're handy -- is to take the belt off the motor and then run it. If the squeaking noise stops, the problem is indeed your belt. Of course, this means your agitator won't move. Replacing the belt should fix the problem.

Water Pressure Issues

• The tub, or drum, fills with water right before the agitator turns on, and water continues to circulate throughout the washing process. As the tub fills and water circulates, you may hear a squeaking or squealing noise if you have high water pressure. This sound is caused by the force of the water moving through the pipes. To adjust this, turn the knobs on the hot and cold valves on the pipes that go into your washing machine.

Considerations

• New washing machines may squeak at first as the parts "warm up," according to the GE Appliances website. The noise should disappear after five complete washing cycles have run on the machine. Unbalanced loads, overly heavy loads and loose items in the drum may also cause noise when the agitator comes on, but these things usually do not produce a squeaking sound.

could be wheel bearing ,could be cv joint could possably be bushings in suspenion.

Chattering is caused by components tooclose to each other. This happens when bushings wear out. Get under there (not whenthe car has been running) and shake the exhaust system and any suspension component to see if you can make it chatter. Then look for why the part is able to move so much.

If you are printing invoices from the MP tray the pickup roller might be squeaking against the separation pad (common with this design). Other common squeak is toner cartridge noise.

Most noises on these models are caused by the cartridge. Typically fuser issues will cause a growling noise not a squeak. If the inside of the machine is dirty you could have toner on the transfer roller busings. Try a different cartridge first, you fastest and most likley problem.

Squeaking noise is usually caused by the toner cartridge, expecially after market ones. But if its not the toner, I've seen the mirror motor cause a rotation noise in the 1300/1200 series printers.

i have found that the toners cause a squeaking noise.if you have old toners change one at a time to find the problem toner

This may be a worn down front brake shoe or pad, some after market pads come with a wear indicator.
This wear indicator rubs the rotor when the pad is in need of changing.

the squeak is coming from the drum unit. If you take out the drum and rotate it by hand it will most likely give you the same noise. you may be able to stop it by pouring some toner on it, but in reality it is more annoying than a problem.
there is a blade that scrapes off excess toner from the drum, it is slightly dry and causes the squeaking, technicians usually use a special powder that looks like baby powder to "lubricate" the blade, and stop the noise.
