The paper in the tray of the manual feed pickup unit is forced against the manual feed pickup roller by the work of the pickup guide plate, and only a single sheet

of paper is separated and moved into the machine by the work of the manual feed pickup roller and the separation pad.

8.5.2 Basic Sequence of Operation

iR3225 / iR3225N / iR3235 / iR3235N / iR3245 / iR3245N

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 regis-

tration roller area.

When the registration clutch (CL2/CL22) 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.
