Panasonic workio sp-190 machine says paper jam

Be sure to check the door in the back by the fuser and check for jams. A lot of folks forget to check there.

This series of machine has frequent issues with the sensors in the paper path to detect timing and position. The sensors are actually optical but the utilize sensor"flags" to interrupt the sesnors light "beam". These sensor flags tend to pop out of position and/or break the springs. I have also seen the actual optical sensor fail.
