    That's an interesting idea. I know a guy that used to use felt or cork, but this seems fool proof.

    I just remove the exit flags.

        Were it me, I wouldn't bend anything. I would remove the foam pad highlighted orange in this photo. Then I would get some sort of self-adhesive sticker that's not porous, like a left-over other-language control panel sticker left over from a setup, cut it to that size and stick it in the other's place. The metal actuator must not be allowed to touch the solenoid core or the actuator will magnetize and you'll get the exact same issue for a different cause. =^..^=

        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.

          I'm surprised more people just don't carry them, we can get em for 12 bucks which equals the time and hassle of repadding IMHO

            I bend that part out, so the plate doesn't come so close to the magnet. I think ONCE, I had to go back, because I didn't bend it far enough. But I've been doing it for years.

            But honestly, JR2ALTA is right. It makes good business sense to just replace them. After all that time tearing the machine apart, may as well get a few extra bucks on the parts. However, you hate to do something, as a technician, that you know is gonna fail.

            Are solenoids polarity sensitive? It occurs to me that sometimes I just wouldn't want to untangle the wires on some machines. But cutting and splicing would be a lot easier, if the solenoid is gonna be replaced instead of fixed.

              Not these, but some solenoids are sensitive to polarity. Some DF's I've seen have a solenoid arrangement where the plunger is in a central position held by a magnet, with a coil on either side to move the plunger In or Out from that central position. Three wire connection.

              There are a couple of Lexmark models that it is impractical to unstring 16" of wire harness back to the controller board. Lexmark includes two splice connectors (aka 2-Port Dry Environment, Single U-Element Insulation Displacement Connector 3M Displacement Connector,12-10 AWG,PK100 - 4YT69'|'562 BOX - Grainger) which are a bit large for the area you have to stuff them, and notoriously unreliable. I throw away those splices and solder/shrink the connections. The wires on the Lexies are color coded so you'd have to be even more stupid than me to get is mis-wired. =^..^=

                I have YET to receive one of these splicing things that Lexmark mentions is included in the media feed clutches! I've done maybe 4(?) of them (PITA!) and like blackcat does.......strip/solder/shrink.

                  To be honest, I've just flat out turned a couple of those machines down. Lexmark ought to be ashamed of themselves. Those things are worse than the color laserjet fuser drive assemblies.
