S7 (MLS)
Paper Length
Sensor
Sensor
Used with the paper width switch to
determine paper size. This sensor is
activated when paper is set for short edge
feed. For example, when the paper width
switch detects A4 width and this sensor is
off, the machine determines A4 is set for
long edge feed. When A4 width is detected
and the paper length sensor is on, then the
machine determines that A3 is loaded for
short edge feed.
