12.3.8 Media size detection control
• The Paper Size Switch (S5) detects the length size (FD) of the media.
1.
The Size Detection Board turns as the Trailing Edge Guide Plate is moved.
2. When the tray is slid into the machine, the Size Detection Board pushes the actuator of
the Paper Size Switch (S5) mounted to the machine frame, thus turning ON the switch.
3. The combination of ON/OFF positions of the sub-switches of the Paper Size Switch
(S5) determines the specific media size that can be either one of the seven different
sizes.
4. If the tray is not slid into position, all of the sub-switches are OFF and the message
“TRAY1 NOT ATTACHED” appears.
12.3.9 Media misfeed detection control
• If the Synchronizing Roller Sensor (PC4) is not activated within a predetermined period
of time after a media feed sequence has been started, the machine determines that
there is a media misfeed. It then gives the message “MEDIA JAM TRAY1” on the panel.
• The media misfeed display can be reset by opening and closing any of the doors.
