10.4 Operation
10.4.1
Drawer
[A] Operation of pickup roller
When the drawer is inserted into the equipment, the lock located in the center of the drawer is released,
and the tray in the drawer is lifted up by the spring. This makes the paper set in the tray contact the
pickup roller when it is rotated.
The driving force of the main motor (M3) is transmitted through the pickup clutch to the pickup roller.
Also the drawer pickup clutch transmits the drive when the pickup solenoid (SOL1) is turned ON. The
pickup roller is rotated one turn by this driving force to pull out a sheet of paper from the drawer. The
pickup roller stops at its home position for each rotation. Therefore, when multiple sheets of paper are
fed, the pickup solenoid (SOL1) is turned ON at each rotation. One rotation of the pickup roller, which is
semicircle shaped, can transport a sheet of paper to the registration roller.
This feeding system has no mechanism specific for detecting the transported paper. Therefore, whether
the paper has been transported to the registration sensor (S4) within a specified period of time or not is
substituted for the paper jam detection.
