Paper that comes from the main machine passes to the entrance of the buffer pass unit.

The right transport motor (right) starts 1.05 seconds after the start of a copy or print job, and six transport rollers on the right side of the path rotate to transport paper to the left side.

The left transport motor (left) starts to rotate 1.05 seconds after the right transport motor starts and this rotates six transport rollers on the left side to send paper to the exit.

The buffer pass unit has eight sensors that detect jams; operation stops when a jam is detected.
