I've been going over this machine with solvent, and I had the carriage moving and the upper reset working. But, in the course of loosening and cleaning buttons, I seem to have locked the machine up. Currently the "middle reset" and "clear tab" buttons are down, and nothing is moving anywhere. I've been using a screwdriver to turn the motor shaft, so I could feel how much torque it took to turn, and now it's locked up beyond just old oil. Is there some sort of release, or anything I should check? Thanks for any suggestions, -Michael Hamilton
