Allan if we are talking about the 2nd feed unit of the machine itself, yes they are a little different and are marked with different colored connectors. My problem however is with the Additional PC-408 (2.700 sheet) and perhaps a related problem with one PC-207 (2x 500 sheets) Both use the same stepper motors. PC-208 has two, one for take up and the same type for feeding the paper. The PC-207 has the same parts and configuration but twice, each for one cassette.

Yes "weight reduction" is a serious issue LOL.

And yes....... I HATE swapping power units. So many connectors with each so many wires to remove, every one can cause an issue later on, and I hate all those stupid wire saddles too....
