Stop registration control stops the Pre-registration Roller. Paper fed by the Pre-registration Roller after being picked up from the
cassette generates an arch due to being pushed against the Registration Roller which has been stopped. In order to align the
image on the ITB with the paper at a specified timing, this control stops paper feed with the paper arched, aligns the image on
the ITB with the paper at the specified timing, and then resumes paper feed.

■ Size Mismatch Detection Control
Whether the size is mismatched is determined by paper length.
The time a paper passes through the Pre-Registration Sensor (PS04) is converted into distance. Then, the calculated distance
and the paper size detected by the Cassette 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)
