Stores finally opened and I was able to oil up the assembly. Unfortunately I
could not see any obvious issues that was causing the Form Feed to
trigger....I think. I was about to investigate the 2-3mm of play on the
Reset Follower Lever when on the downside of a lobe (If I held back the
slack a comma wouldn't cause a form feed So I'm curious what would happen if
I took out most of that slack but left enough that it wouldn't cause the
Form Feed to stop working) when I lost power to the selector solenoid. CR1
on the PA81821 shorted out and I can't continue investigating until it's
replaced. I'll try and get in to the shop tomorrow to source a replacement.
