Thanks Spanky, you change these out as a set?

There are two pwb boards in the punch unit, one is an LED PWB the other a transistor PWB. They are at the entrance and are used for edge detection and jam detection. I replace these often for such issues.

****UPDATE*****I ended up removing the Punch unit, and now the misfeed error on start up is gone. I think one of the sensors in the Punch unit is bad or blocked.

On Power up, Machine displays "misfeed occurred" in the finisher. Checked Sensor switching FED paper inlet ...etc. in simulation mode. Machine does not clear the jam indication unless I restart the copier. Updated to current firmware.
