CHAPTER 7 PICK-UP/FEEDING SYSTEM
b. Operation
In the case of the deck right/left, two sensors are used to detect the position of the deck, and
combinations of the states of the sensors (on/off) are used to find out the level of paper.
For the absence of paper, an exclusive sensor is used. (See 3. "Detecting the Presence/Absence
of Paper.")
