2.1.8 ORIGINAL SKEW CORRECTION MECHANISM

[A]
A680D510.WMF
The transport belt motor remains energized to carry the original approximately 7
mm past the left scale [A] (see the middle drawing). Then the motor stops and
reverses to feed the original back against the left scale (see the bottom drawing).
This forces the original to hit the left scale and this aligns the trailing edge to
minimize the original skew on the exposure glass.
If thin original mode is selected, the original is not forced back against the left
scale. This is to prevent any damage to the original.
After a two-sided original has been inverted to copy the 2nd side, it is fed in from
the inverter against the left scale (see the bottom drawing; the top two drawings do
not apply in this mode).
The amount of reverse feed against the left scale can be adjusted with SP modes.
