(12-1) Right cassette primary paper feed
As paper feed clutch 1 (PFCL1) turns on, the drive is transmitted to deck paper feed
roller 1 and the upper and lower deck separation rollers, starting primary paper feed
from the right cassette. The upper and lower deck separation rollers ensure that the
paper is fed one sheet at a time and that it is fed into the copier correctly.
To prevent multiple sheets from being fed, there is a torque limiter on the lower deck
separation roller.
