direction at a speed of 533 pps to move the paper feed tray upward.
- The upper tray pick sensor turns on to stop the upper tray lift motor.
- For plain paper, the tray paper feed motor turns at a speed of 500 mm/s to start separating the
paper in the tray. For thick paper, the motor turns in the reverse direction at a speed of 250 mm/s
to start separating the paper in the tray.
- For the upper tray, the tray paper feed motor stops when the paper has been fed 14.7 mm since the
registration sensor turned on. For the lower tray, the tray paper feed motor stops when the paper
has een fed 19.1 mm since the registration sensor turned on.

(4) First paper feeding to horizontal feed lock
- When an Entry signal for the first paper is received, the entrance motor 1 turns in the reverse
direction at the same speed as that of the motor in the host machine and the reverse motor turns
in the reverse direction at the same speed as that of the motor in the host machine, thus feeding
the paper to the horizontal feed lock.
- The reverse motor stops when the paper has been fed 51.2 mm since the reverse timing sensor
was turned off.
- An Eject signal is sent when the paper has been fed 12.3 mm since the delivery sensor 2 turned on.
(5) Second paper feeding to standy position
- After the reverse feed motor stops as mentioned above, the tray paper feed motor turns in the
normal direction at a speed of 800 mm/s to start feeding the paper to the standy position.
- In case of paper feed from the upper tray, the tray paper feed motor stops when the paper has been
fed 64.6 mm since the registration sensor turned off. In case of paper feed from the lower tray, the
tray paper feed motor stops when the paper has been fed 10.3 mm since the registration sensor
turned off.
- The reverse motor stops when the paper has been fed 51.2 mm since the reverse timing sensor
