Paper Size Detection
Tray 1 (MPT)
Paper width (size in fast scan direction) is sensed by the voltage corresponding to
the Tray 1 (MPT) Paper Size Sensor resistance. Tray 1 (MPT) Paper Size Sensor
resistance is determined by the position of the front and rear side guides. Some
variation in values is normal within the specified range.
Note
Paper length (size in slow scan direction) is sensed by measuring how long
paper takes to pass Registration Sensor.
