Install the drum unit into the machine without the toner cartridge in it and close the front cover. – If the grinding or clicking noise occurs, the drum unit is the cause of the noise. The drum unit (DR720) will need to be replaced to resolve this issue.
Check the printer driver settings. Check your application`s settings. Restart your Brother machine and the computer. Reinstall the printer driver.
The network connection between your computer and the wireless router may be unavailable or set up incorrectly. If you replaced your wireless router or access point, or changed its settings, reconnect your Brother machine to the new wireless router or access point. >
Grinding noises are associated with rotating parts and rotating systems; any part or system that rotates can cause grinding.
The most common causes of grinding noises in automobiles are worn-out brakes, a faulty CV joint, or transmission issues. It`s important to note that, whichever component is causing the grinding noise, it needs immediate repair. The following are common causes of grinding noise in automobiles.
1: Check Printer Power, Cables, and Paper

Check that the correct paper is properly loaded into the printer and is not jammed. Replacing damaged cables, plugging in loose or disconnected cables, and fixing paper jams as necessary may resolve the issue.

NOTE: If the paper guide is too tight against the rear edge of the paper stack, the machine may make a loud clicking noise since the gears that drive the tray up may be binding. Be sure to leave a very small gap at the rear edge of the paper stack before locking the tab.
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.
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.
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 biggest tell is misprinted pages. If you have a new Brother toner, and the printer still puts out pages with obvious streaking on them – it`s time for a drum unit replacement. Don`t let bad printouts make you seem unprofessional – replace or fix your Brother printer drum today!

ANSWER : Not being able to actually hear the noise, I would guess it is possibly coming from worn gears driving the fuser assembly. Put your ear at the back of the machine and listen for the noise.

Brother MFC-9400CN Print Unable 2A FIX
ANSWER : I had that same problem, I have a MFC-9840CDW also. I went in and removed the three components Toner Tray, Transfer belt, and waste toner box. First thing no one mentioned is that you cannot just put your toner tray down when you take it out. Look at the bottom, those are light sensitive drums on the bottom. I put mine on its side with the bottom away from light and then covered it with a small black clean trash bag. Nothing touching the bottom, and protected from light. Also the transfer belt should not be placed down on the actual belt. The belt is basically the width of the unit and very delicate. same thing, on its side and covered with a clean bag. away from kids, dogs, cats, hamsters etc…lol. The waste toner box is safe to put on your desk.
