HP Officejet Pro 8620 Motherboard Replacement

Введение

The motherboard is the brain of the printer, so if anything goes wrong with it, your entire printer becomes worthless. In order to access it, you will need to remove the side panel.

To remove the motherboard, you will need to remove several connectors, so a set of small hands will be helpful. You will also need a screwdriver to remove the four 8mm T9-Torx screws securing it in place.

Be sure to ground yourself and the device when removing the motherboard and its connectors so short circuits do not occur.

Be sure to set a space aside for the screws so you don't lose them.
