I'm sure I did something to cause this, but I don't know what. I removed the title rack to get at the mech computer when that failed. I eventually bought a replacement mech computer (months later), which fixed the initial issue. However, once I put the title rack back into place and plugged in what I have assumed is the only connector, the pages don't advance when I push that button. I can hear something trying to do something for a few seconds when I push the button, but nothing moves.
I also cannot advance the page using the handwheel on the shaft (I don't know if I should be able to do that or not, but it is frozen).
Any insight would be appreciated.
