6.19. Mechanical Operation
6.19.1. Printing
The main motor gear rotates as shown in figure.
GEAR DRIVE OPC drives each part of fixing and developing.
When paper is fed from the standard cassette, the plunger of solenoid is pulled to drive PICKUP ROLLER (STANDARD), then
the roller starts feeding paper.
When paper is fed manually, first the plunger of solenoid is pulled to stop REGISTRATION ROLLER. After a few moments turn
off the solenoid to drive REGISTRATION ROLLER, then the roller starts feeding paper.
6.19.2. Scanning (ADF)
• DOCUMENT TRANSMISSION (ADF)
The frictional force between SEPARATION ROLLER (DOC.)and SEPARATION RUBBER makes PICKUP ROLLER (DOC.)
move downward from standby position to pickup paper.
Pick-upped paper is separated by SEPARATION ROLLER (DOC.) and SEPARATION RUBBER (DOC.), and then fed by FEED
ROLLER (DOC.).
After being read by CIS, the paper is ejected by ROLLER DOC EJECT.
