How to fix an Epson 3170 scanner.

After two days of trying different software solutions to make this piece of shit work, I looked inside, and found the real problem.

You see the two shiny screw heads holding down that metal plate under the pulley? The plate was originally held down by two little plastic tabs. You can see where each one broke off on each side of the plate. I drilled two holes in the case, and used two bolts I had lying around to hold down the plate. That plate has a spring to tension the belt that moves the scanner lens back and forth. Those two little plastic tabs never had a chance. Great design, Epson.
