turns in the normal direction at a speed of 400 mm/s to start feeding the paper to the reversal
standy position.
- For the upper tray, the tray paper feed motor stops when the paper has been fed 64.6 [mm] since
the registration sensor turned off. For the lower paper feed tray, the tray paper feed motor stops
when the paper has been fed 10.3 mm since the registration sensor turned off.
- The reversal motor stops when the paper has been fed 19.2 mm since the reverse sensor turned
off.
(3) Second paper feeding for separation
- After the paper feed motor stops as mentioned above, the upper tray lift motor turns in the reverse
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
