Control purpose
- This is to prevent the contact with lead roller 1/2,
when the leading edge of original goes through
the lead roller 1/2.
- This is to prevent the unstable operation of
original due to reaction when the trailing edge of
original goes through the lead roller 1/2.
- This is to prevent the
contact with delivery
roller when the leading
edge of original goes
through the delivery
roller.
