COPY IMAGE ADJUSTMENTS: PRINTING/SCANNING
ADF Skew Correction
If the skew with A4 SEF paper is more than 0.5/200 mm in the main scan direction,
you can adjust the position of the ADF hinge [A] or adjust the appropriate SP codes
below.

NOTE: Normally, the interval sensor detects the leading edge of small originals
(B6, A5, HLT), or originals for duplex copying, and delays the start of the
scanning roller for the prescribed number of pulses to buckle the paper and
correct skew. This feature can be switched on for all paper sizes with
SP6020 (ADF Contact Mode In/Out). However, switching this feature on for
all sizes reduces scanning speed slightly.
