    Replacement Foam for feed solenoids

    Anyone know where to get replacement foam for hp laserjet feed solenoids. I have been buying the solenoids but it seems a waste of time and money if I could just plop on a strip of foam. Thanks for any info!

    Go here for more info on this problem.
    This thread is for HP LJ 4100's but applies to your problem

    HP Laserjet 4100 Error (13.1) - fixyourownprinter.com

    You can use many types of material to dampen the noise, electrical tape, foam strip, felt.
    Just remember not to defeat the action of the solenoid.

    I've been using black tape for quite a long time. =^..^=

    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.

    Black tape for me as well, 2-3 layers.

    I have some felt circles... but some solenoids don't have enough clearance for them & the felt will bind it's operation.

    Today I tried something a little different. I used the hook side of adhesive Velcro. I still damps the noise, and there isn't much risk of the adhesive bleeding through. I think either side of the Velcro would work fine. =^..^=

    I use Canon separation pads (FC5-4368) that I cut down with a razor blade to fit. Almost all of the solenoids I fix are too small for felt. These just dampen the sound.

    Another thing that works is rubber. I've punched some 13mm disks of rubber from a bicycle inner tube. A small spot of cyanoacetate secures the disk where you need it. =^..^=

    Re: Replacement Foam for feed solenoids

    back when i used to work on HP laser printers 10 years ago, i used to have a supply of 3mm adhesive backed foam that i used for this specific purpose.

    I was working on the canon SX engine HP Laserjet II and from memory it was a couple registration solenoids that caused interesting paper jams when the factory foam on the tops of the solenoids disintegrated into a sticky mess. Good to see absolutely nothing has changed since then

    BTW, it was essential to use something as simply removing the factory foam and and cleaning them didnt work, metal on metal resulted in some kind of residual magnetism and the solenoids stayed activated for way too long..

    If at first you don't succeed, try the way I told you how to do it in the first place.

    Yeah, I discover that. I had to replace a couple before I learned. =^..^=
