HP LaserJet 4100 printer

HP LaserJet 4100 picks up multiple sheets from tray 2, have already tried replacing pickup/separation rollers on both tray 2 and printer itself.


thanks Gavin
The separation roller in the cassette is connected through a torque limiter that sometimes wears out. Pull that roller back off, and you can slide the torque limiter off after it. Its part number is RB1-8974. It's actually just a couple of strong magnet plates with iron filings packed between them; as the iron filings wear out, its grip weakens. It costs more than the separation rollers. A third thing to try is the spring tension that lifts the roller up inside the cassette. If you flip the cassette over, you can see that the spring hooks onto a lever. There are three notches in the lever, try another notch and test. But I'd go with the torque limiter first.
