LaserWriter 12/640PS

Hi,
I have a 12/640PS that stops advancing the paper just before it
turns to go horizontal toward the toner. The pickup roller solenoid works,
and the roller rotates, but the pickup drive shuts off too soon and lights
the paper jam LED. I saw only one paper sensor, just before the final roller
of the pickup drive assembly, but the paper never gets quite that far. Is there another
one I missed that could be failed? Or do the pickup drives fail in this way?
I was expecting a mechanical pickup assembly malfunction. Thanks!

Peter
