Solenoid on HP 4350

[Kidaver]

I had a LJ 4350 that would pull an extra page after any print job over 2 or 3 pages but would never throw a jam code. I didn't find anything on here but did find the solution on an HP forum and thought I'd share it with everyone. On the front right side near the gear assy is a little solenoid. It's black with 2 black wires and an L arm plate with small spring. The pad on the solenoid under that plate will wear down and the adhesive resin will cause that L plate to stick and feed an extra sheet of paper that will jam up underneath the drum. So just a heads up if anyone comes across this. Just clean up the L plate and solenoid surface and place some electrical tape there. Also I don't know what it is with HP but why do the torque down the easiest to strip screws in their machines!

Going further its the same with 2300, 4000, 4050, 4100, 4250 4350, P4515, 4700 and many others have that same issue why they use foam that deteriorates like that IDK.

Thank you!

Hi; if you don't already own "ACR" (anti-camout-ribbed) screwdriver bits (#2 Philips), I'd URGE y'all to buy a bag full....I don't hardly ever get STUCK (pun intended) on screws any longer, unless some DOLT rammed it in too tight with one of them! I bought mine from Katun, I think but I know snap-on tools makes 'em.

Also, the sticky solenoids were invented by Samsung, so HP probably started using them so we techs. wouldn't lose our sweet cushy HP service jobs!!

It's not a bad printer, but I do not see them often anymore.Thanks for sharing!
