Size Mismatch Detection Control

Whether the size is mismatched is determined by paper length.
The time a sheet of paper passes through the Pre-Registration Sensor is converted into distance. Then, the calculated distance
and the paper size detected by the Cassette 2 Size Detection Switch are compared. If the difference between them is 20 mm or
more, it is judged to be size mismatch.
In this case, paper is not delivered, but stopped instead with a jam detected.
(Jam code: 0D91)
