last sheet of paper.

8.5.2 Basic Sequence of Operation

The multi-pickup roller starts to rotate when the manual pickup clutch (CL1) goes on to start
upper separation to pick up a single sheet of paper. When the leading edge of the sheet
reaches the registration sensor (PS26) and is moved a specific distance, the manual pickup
clutch goes off, causing the sheet to arch in the registration roller area.
When the registration clutch (CL2) goes on, the manual feed pickup clutch (CL1) once
again goes on to pick up paper. The manual feed pickup clutch (CL1) goes off immediately
before the trailing edge of paper moves past the manual feed pickup roller; thereafter, the
registration roller serves to pull off the paper.
