DC250 012-322 and 012-323

Anyone know what these are and what to do to fix them?

Seems to be intermittant in that I can power off the printer and sometimes they happen and sometimes they don't - I suspect a sensor issue somewhere but which one.

For once, Google wasn't much help

The wire harness going to the hole punch unit gets a lot of stress over time as the hole punch moves forward & back. Remove the finisher rear cover & locate the wire harness going to the hole punch. Remove the tie wraps. Repair any broken wires or wires with cracked insulation. Secure with electrical tape.
