Theory of Operation Ver. 1.0 Jul. 2009
C. Operation timing
(1) When the tray is slid in
• When the tray is slid into the machine, the paper feed tray1(2) device detection sensor is
blocked. The machine then determines that the tray is slid into position.
• The paper lift-up plate is lowering when the tray is slid out, so that the paper feed tray1(2)
upper limit sensor is unblocked.
• Determining that the paper feed tray1(2) upper limit sensor is unblocked, the machine
lets the paper feed tray1(2) lift-up motor rotate to start the up operation of the paper lift-
up plate.
• When the paper stack is raised to a predetermined height after the up operation of the
paper lift-up plate has been started, the paper feed tray1(2) upper limit sensor is blocked.
• Determining that the paper feed tray1(2) upper limit sensor is blocked, the machine stops
the paper feed tray1(2) lift-up motor to complete the up operation of the paper lift-up
plate.
• Control is provided to make sure that only one tray performs the up operation at one
time.
• If the tray is slid out during the up operation of the paper lift-up plate and accordingly the
tray1(2) device detection sensor is unblocked, the up operation of the paper lift-up plate
is terminated.
