Brother mfc8710 overheat - Brother HL 5250DN Laser Printer

1) Unplug the electrical cord. 2) Loosen the bolt holding the motor to the frame. It should freely move up and down. 3) Remove the belt from the motor and wheel. 4) Replace the belt by placing it into the large wheel first then do the reverse. 5) Resecure the motor. Make sure the belt should be a little loose (tension). Too tight of a tension, would cause the motor to be slow and overheat.

The best way to deal with envelopes is to either get a label printer like a Brother, or get laser safe window envelopes. Envelopes cause many problems and if you are going to print a large number of them you will wear out the fuser prematurely because the outer edges of the fuser will overheat feeding the narrower paper.

i'm wondering if it is able to turn on after a short while? this brother is equipped with a computer and like other computers it can overheat and shut off to prevent destroying the computer. i don't have a repair manual so this is not a guaranteed answer. anyway, try to use a cooler room and make sure there isn't any fabric or anything else around the sewing machine. this will keep the computer from cooling down. it is maybe helpful to move the machine a small distance from the wall. anyway, this may help.

You have to get that fan working well because if you don't you will fry your motherbord and you will start poping caps computer run very hot

Does it loose power? You can have a overheating in the coolant sensor and oil is not hot... this usually is a problem with the joint of the head of the motor leaking pressure to coolant circuit.

try windex or windshield washer fluid

Probably thermostat sticking or bad water pump. CK the belt to the water pump to see if it's loose. If the thermostat sticks, water can't be pumped thru the motor, overheats and overheats the radiator causing hot water or steam to build up pressure.and the relief valve will open allowing the peessure to be relieved and blows coolent everywhere. If the radiator overheats turn off motor wait until the radiator cools before removing cap. been there, done that-------once
