The primary paper feed unit was changed to stop paper
jams and abrasive wear on the rollers.

can be double feeding. Test for double feeding before finishing.
TIP: To do a strict test for double feeding fasten a
transparent sheet with tape as the bottom sheet in the feeder
and five sheets on top to send through the feeder.
