E. Media width detection control
• The Paper Size Sensor (PC23) detects the width of the media being conveyed.
• If the width of the media that has moved past the Paper Size Sensor (PC23) is 210 mm

(A4 width) or more, the leading edge of the media pushes up the actuator of the sensor,
thus blocking the sensor. When the sensor is blocked, the machine considers that the
width of the media is equivalent to A4 width or more.

• If the width of the media that has moved past the Paper Size Sensor (PC23) is less than

210 mm (A4 width), the actuator of the sensor is not moved and the sensor is left
unblocked. When the sensor is unblocked, the machine considers that the width of the
media is a small size (B5 size or less).

• For media size detection, the machine recognizes the media size using the media size

setting made in the controller and determines it after the media has actually been fed
through. The media size detection results are used in the “PPM control,” to be described
later.
