Media size error detection control

• To prevent incorrect printed pages, the size of the media being conveyed is detected
using the registration sensor and media feed sensor.
• The length of the media is detected based on the value calculated using the period of
time that begins when the sensor is activated and ends when it is deactivated for each
media source.
• For the lower feeder unit, even if the media feed sensor does not detect a media size
error, the downstream registration sensor makes an error check again.

output control.
