Remaining paper detection control

A. Paper near-empty control
• The manual tray is not mounted with any near-empty detection mechanism.
B. Paper empty control
(1) Paper conditions
• The manual tray is provided with the manual paper empty sensor (interrupter-type photo-
sensor) and the manual paper detection sensor (reflector-type photosensor).
• The following three types of paper conditions are detected according to the combination
of the states of the manual paper empty sensor and manual paper detection sensor:
"Paper remaining"
"Paper not loaded in place"
"Paper empty"
(2) Manual paper empty sensor
• When the paper is loaded in the manual tray, the paper empty detection actuator is
pressed and lowered by the paper. The paper empty detection actuator is lowered to
block the manual paper empty sensor.
• When there is no paper on the manual tray, the paper empty detection actuator is raised.
The paper empty detection actuator is raised to unblock the manual paper empty sensor.
