[E]
Paper entering the diagonal transport unit is transported down to the
horizontal transport unit. The front side of the paper advances more than the
back side due to the front transport roller [A] being larger than the back
rollers. This causes the paper to skew as it enters the diagonal transport unit.
This skew prevents the diagonal transport guide [B] from catching the edge of
the copies.
The paper is then moved to the front by the diagonal transport rollers [C].
Where it is aligned as it is guided by the diagonal transport guide [B].
The brake roller [D] prevents the rear side of the paper from falling forward.
If the paper is traveling lengthwise, the pressure release solenoid [E] turns on
to prevent over skewing.
