13.3.8 Tray detection control
• Detects the Tray presence with the Paper size switch (S5).
1. Setting the Tray to the printer will make the detecting plate press and turn ON the actu-
ator for the Paper size switch (S5) mounted on the Copier frame.
2. The switch will be OFF if the Tray is not properly set, and “TRAY1 DRAWER OPEN
(magicolor 5440 DL)” or “PAPER EMPTY TRAY2 (magicolor 5450)” will be displayed.
13.3.9 Media misfeed detection control
• If the Synchronizing Roller Sensor (PC4) is not activated within a predetermined period
of time after a paper feed sequence has been started, the machine determines that there
is a media misfeed. It then gives the message “MEDIA JAM TRAY1 (magicolor 5440 DL)”
or “PAPER JAM TRAY2 (magicolor 5450)” on the panel.
• The media misfeed display can be reset by opening and closing any of the doors.
