period of time between when Synchronizing Clutch CL1 is
energized and when PC2 is blocked (L), the paper size
detected is longer than the size data sent from the
controller by +260 mm or more.

The paper size detected based on the period of time
between when CL1 is energized and when PC2 is blocked
(L) is more than the size data sent from the controller by
±20 mm or more.
———
Paper left
PC2 is unblocked (H) when the Power Switch is turned
ON, CPU is reset, or cover is opened and closed.
