Question about HP LaserJet 1200 Printer
I have disconnected the two gears that has a spring attached and now I can't get it to stay in place. The printer can make a full rotation around and then the area on the gear that is flat, the selnoid catches on the first tooth and won't release so it can go into the next rotation,
I would appreciate any help you could give me: Fitness36@yahoo.com

Where is the area that is flat ending up when it gets stuck?
Also, what repair was made on this printer? DId you take out the motor at all?
Also, if you removed the side panel.. is the clutch correctly placed? And is the spring in there?
Also, be sure to align the clutch on the pickup roller shaft with the follower (large plastic tab) (callout 2) on the paper lift plate
