Skew Correction

The skew correction sensor [B] detects the leading edge of the original after it passes through the separation area. When the leading edge reaches the entrance roller [C], the original is fed a bit more so that it bumps into the entrance roller [C], to make slack for skew adjustment.

For small paper (B6, A5, B5, HLT) or duplex printing, after detection by the interval sensor [E], the original bumps into the pre-scanning entrance roller [D] (this is a second skew correction, in addition to the entrance roller).

With SP6-020-001, the 2nd skew correction can be enabled for all paper sizes. But if this is done, the process speed becomes slower as shown below.
