What would cause this HP LaserJet 4250n to overfeed? What I mean by this is that I only want to make one copy, but the machine pulls two sheets through, and the first sheet stops as a quarter (1/4) of the lead-edge is exiting. This problem is only with the second paper cassette. (The machine has two paper feed drawers and a bypass tray.) Thank you for any help given.

Re: HP LaserJet 4250n
The problem more than likely is the Paper Feed Solenoid. Look in the event log. You will see 13.98, 13.02, 13.03 errors if the solenoids are having issues.

Definitely a sticky paper pickup solenoid. Replace the solenoid unless you know the trick into replacing the sticky foam.Comment

Re: HP LaserJet 4250n
Ditto that. The test is just to manually hold down the actuator for 10 seconds, then let go. If there is any delay in returning, you know that the foam is getting sticky.
I'll usually chemically clean away the old foam and any remaining two sided tape and adhesive. With a hole punch I'll punch a nice 1/4" disk of inner tube, or scrap rubber transfer belt, then glue it in place with cyanoacetate. The adhesive will never ooze through the rubber. It won't ever come off. And it won't ever make noise.
When I first discovered this fix I would just scrape away the foam and let it "clack". The drawback to this, is that the metal actuator will eventually magnetize if it contacts the metal solenoid core, and you'll get exactly the same effect as the sticky sound damping foam. Then you have to replace it. =^..^=If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.
