Hp HP LaserJet IIIP+

Scanner motor cycles repeatedly on HP IIIP

I have a HP IIIP where the scanner motor repeatedly spins up to speed, cycles the system but does not grab a piece of paper, spins down and then repeats. Total time of each cycle is about 40 seconds. There are no error numbers reported after a Self Test. When the printer is powered off then on it is fine for an hour or so then starts cycling and then draws a sheet of paper each cycle.

Any thoughts?
I've never seen this behavior in a IIIP. Best guess would be the DC controller. That's where the power and signal to run the scanner comes from.

I swapped out the DC controller and it fixed the problem.
