Thanks for this guide. I never would have found that fourth screw without this guide. The illustration of the "clip" for removal of the power quadrant face could have been more detailed and/or you could have said in the description, "Feel for the TAB on the right center of the power button quadrant behind the "cartridge door open" feeler and push it toward the outside of the printer". Other than that, this was great.

Thank you for posting this. In place of the pliers, I recommend using a small reversible ratchet offset (mine was 3-1/4"W x 6-3/4"L x 1/2"H) to remove the 4th screw. It won't slide of the screw like pliers and will make both the removal and replacement much easier.
