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.

MEMO:
The manual feed pickup unit of this machine is not equipped with a sensor detecting the last sheet of paper.
