Beating Noise emanating from the Printer Brother MFC8840D

Hi! Laterly theres been a beating noise coming from the cartridge or somewhere which is loud and irritating, that have triggered us to off the printer. This started after the comment "Change the drum" appeared on the printers screen. We are not able to print also. I would appreciate if anyone could help me out on this issue.

Worked on one of these today that had a broken gear on the fuser. It takes about 8 screws to pull out the fuser fom the back of the machine, but the gear is visible with the fuser removed. If it is broken or teeth missing, I found a new one at precision roller for $129.00. They offer the gear only but I didn't want to take the time to replace it and other parts were worn anyway.

My neighbor has a deer repeller that emits a high frequency sound that is supposed to be inaudible to humans, however I hear it and it is painful.

Phone you local environmental health department. This is the place where the health inspectors are for food premises. Ask them to come and evaluate the sound from it. They also deal with noise complaints. If it triggers headaches and irritability then it is affecting your health and must be stopped. It may be possible to mount it differently so the noise is projected away from your property. I may also be installed correctly or too close to your property.

A quick Google shows me that they are supposed to be inaudible to humans and also that they should only come on when a deer approaches.

Why is my engine so loud when driving down the road?

Hi George:
I'd suggest that you start by checking for leaks in the exhaust system.

It very well could be the strut.
smaller chance could be the CV axle.
Also have the splash guards/heat shields checked to make sure they are all tight in place.

Loud grinding noise. Paper only coming half way out then getting Jam notice. Loud grinding is very loud.


Grinding noises indicate either gears that are self destructing or something is stuck inside. Take out the cartridge(s), remove the paper and all the plastic that comes off. Unplug the cables. Now lift the printer, turn upside down and shake. If there are broken gears a local repair shop might try to fix it but most stores refrain from this.

Well in case you didn't get an answer somewhere else the part making the noise is called the color wheel and has a motor that spins it at a high rpm. When they go bad they squeal real loud. You're looking at maybe $300-400 to fix parts and labor.

This seems to be a classic case of "disentegrating exhaust system syndrome." There is either a hole(s) somewhere in your exhaust system or there is a leak somewhere. Probably the easiest way to tell where the noise is coming from is to start your car and just listen around in the engine bay, under the car, and at the muffler. Also do a visual inspection of the exhaust system to see if you can see any holes in the piping. I have also seen hairline cracks in the exhaust header itself that can cause the loud ticking noise that can be a little tricky to track down.
