MPC 2500 SC442 what is the problem?

sc491 is a high voltage output error. Combined with your jamming issue, it sounds like a possible electrical problem somewhere. A good first step is to turn the machine off and unplug it, then take off the covers and reset any connections or cables you can get to.

If the problem persists, you should have a service technician take a look at it because it might need a board replaced.

SC491 error is a general error meaning service needed
