Question about Xerox Phaser 7750DN Laser Printer
How difficult is it to change an engine control board in a Xerox 7750?
Is it just a matter of unplugging the cables on the old board and plugging into the new one/
It's easy all you do is the following..
remove the top cover
remove the rear cover
them the right cover
then on the top left side of the rear cover there should be a metal cover protecter, remove that and you will have access to the engine control board wires. Disconnect those wires CAREFULLY should be under the image processing board. Remove the image processing board then there should be 4 or 5 screws holding the image processing board cage. should be on one on every corner. Then the cage should pop up with no problem and the engine control board is under it.
