SP 5-181-6 to –13 does similar functions for the optional paper trays.
The machine disables paper feed from a tray if the paper size cannot be detected (if the
paper size actuator is broken or no tray is installed).
For non-standard paper sizes, if they are not visible on the user tool screen for selecting
paper sizes, then set SP 5112 to 1. If the user selects one of these sizes, auto paper size
selection is disabled.
6.10.5 PAPER HEIGHT DETECTION – TRAYS 1 & 2
Two paper height sensors [A] [B] and actuator [C] are built into the paper tray lift motor. The
paper height sensors, detect the amount of paper in the tray.
The actuator [C] has two semicircles, and it is engaged with the lift arm shaft via gears. The
paper height sensors detect the paper size depending on the position of the two
semicircles. The list shown below shows the detection combination of the two sensors.
The paper remaining status bar is displayed in the tray selection icon on the LCD.
