Good Monday to all! I am having problems with an MX-FN13 in an MX-M260. The problem is intermittent, only happening maybe once in 300 copies. The machine will be going to a location outside our servicing area and I would like to get it 100% before it leaves the shop. I am testing this off-lease machine by running 2 sided 8 1/2 x 11 copies. The jam code is FPPD1_N. Not positive it was a bad sensor (and not having the sensor or a part number) I continued testing. Turns out, it looks like the finished copy is trying to exit the machine body on the wrong side of the FN13 paper gate. The FPPD1_N is coming up because the paper isn't getting to that sensor due to the diversion of the paper gate. If the paper has been copied on the first side and needs to go back for the back side copy, the paper goes above the gate. If the copy has been completed on both sides, it should exit below the gate.
I removed the front cover of the FN13 and watched the gate solenoid while the paper exited. The solenoid does not have a quick, crisp action. The plunger seems to move in slow motion. I did not find any binding when I removed the solenoid & plunger & manually activated the gate as well as the plunger. I don't have prior experience to know if this slow action of the plunger is normal. There doesn't seem to be the need for real quick solenoid action unless it is causing jamming.
Any input would be appreciated.
