I will come back with more information - and possibly more questions.

How the assembly line worked is a mystery to me. I spent hours trying to discern the "magic" of re-assembling the top and bottom halves. I never figured it out. There must have been some tool or jig aid that was used on the production line. But I am not as mechanically inclined as some other individuals. Maybe you will discover the clever method they used. I didn't.

The corrosion on the bottom board is probably causing the fault. It needs to be thoroughly cleaned up. Check for circuit traces that may have been damaged by the corrosion.

I would attempt to keep the printer attached, but try to keep it away from the board cleaning process. Easy to say, but difficult to accomplish I realize.

Keep us posted on your progress.

Don't ask me I just lurk here.
