2)Operation of the paper feed tray
•
The paper tray sensor detects the paper tray is properly postioned in the copier.
•
The spring under the bottom plate of the tray then lifts paper.
•
With the Start key, the main motor starts rotating and transmits the rotation to the
middle gear via drive gears.
•
Accordingly the paper feed solenoid is turned ON. The paper feed roller starts
rotating to send the paper in the tray to the registration rollers.
•
The paper separation fingers prevents double sheet feeding.
•
The registration solenoid starts working to rotate the registration roller when the
defined time elapses after the optics system starts (uniform-velocity unit).
Accordingly the paper is sent into the machine and the original and copy paper are
registered there.
