The contact operation of the rollers is the same way of the LCIT exit roller contact mechanism that is
previously employed.
As an example, the contact mechanism of the LCIT exit rollers is explained as follows.
When the LCIT exit roller contact motor [A] is ON, it turns the cam [C] on the driveshaft via the belt [B].
The roller contact arm [D] moves up/down in conjunction with the cam, and this mechanism separates
the slave exit roller [E] from the drive exit roller [F]. The LCIT exit roller contact sensor [G] detects
whether or not they are in contact.
