I have researched this problem on this website and found a thread from August, 2010, The thread, at


says, "you have to remove all the outer panels, separate the top half of the machine from the lower trays, and then remove the top plate covering the lower trays to remove & replace the PCA board."

I think my problem might be just an intermittent contact somewhere which could be fixed with some DeoxiT D100L contact cleaner.

I just need to learn how to take the printer apart.

Can anyone help?

Thank you,
