ORIGINAL SKEW CORRECTION

[A]
[B]
The transport belt motor remains energized to carry the original to the right about 7
mm past the left scale [A]. Then the motor stops and reverses to feed the original
12 mm to the left against the left scale to correct skew. This forces the original to
hit the left scale, which aligns the trailing edge to minimize 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 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 [B] without skew correction.
NOTE: The bottom drawing applies to duplex scanning; the top two drawings do
not apply in this mode.
The amount of reverse feed against the left scale can be adjusted as follows:
• One-sided originals, and side 1 of two-sided originals: SP6006-3 (DF
Registration Adjustment – Leading Edge Duplex 1st)
• Side 2 of two-sided originals: SP6006-4 (DF Registration Adjustment – Leading
Edge Duplex 2nd).
