Re: KM 4050 Cass 1&2 Not working
what does "not loading" mean? not lifting, not feeding?
any codes?
did it work before you started refurb? -
Re: KM 4050 Cass 1&2 Not working
Check for the paper bits in the paper tray connector on the copier side and the tray side. A very small amount could be well packed in the connectorsComment

Re: KM 4050 Cass 1&2 Not working
Did they work before you took it apart? Have you gone into the service mode and executed sim 906? There are some surface mount components that sometimes go on the engine board when the lift motor goes, but at least try Sim 906.Comment

Re: KM 4050 Cass 1&2 Not working
A shorting lift motor will blow the driver circuitry on the engine PWB. If you had one tray that worked and one that didn't, and swapped the motors, it would blow the other driver circuit, and neither would work.
Order two lift motors and an engine PWB. Replace them all as a set. You may have to do a U906 when you're done. =^..^=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.
