<Paper Pressure Release Mechanism> (Except 3rd Drawer)
If the drawer is pulled out when a sheet of paper is pinched between the Feed and
Separator Rolls, that sheet of paper is left inside the copier and it becomes difficult
to remove it.
This copier is therefore provided with a mechanism that releases the Separator Roll
from the Feed Roll when the drawer is slid out of the copier.
The paper pressure release mechanism consists of the Pressure Release Spacer
on the Separator Roll Assy and the Pressure Release Rail fitted to the upper part of
the Drawer Rail. When the drawer is slid out, the Pressure Release Rail presses
down the Pressure Release Spacer, which results in the Separator Roll being dis-
engaged from the Feed Roll.
