Roller (518), which rotates one revolution. The paper is separated into individual sheets by the L and R Paper Separation
Clips (809 and 811) and transported to the Feed Roller (526).
3. After one revolution the Paper Feed Roller (518) stops, releasing the paper. The Feed Roller (526) transports the paper to
the drum area.
