Bottom Fan Replacement

The bottom fan maintains the proper temperature around the motherboard and protects it from overheating. If you can hear a strange sound coming from the bottom of the machine, at first you should check if something is not obstructing the fan’s blades from moving. If the blades do not rotate at all even though the printer is on, the fan is probably faulty and needs to be replaced. Follow the instructions from this manual to avoid motherboard failure in your printer.

The following manual shows the M200 repair work. For the M300, these procedures are the same.
