Stack Tray Paper Full Detection Control
The paper full state of the stack tray is detected by the stack tray paper height sensor (S9)
and stack tray lower limit switch (SW2).
Stack Tray Lower Limit Switch (SW2)
ON
Stack Tray Paper Height Sensor (S9)
ON
The paper full state of the stack tray is detected in the following cases:
• When the power is turned on or during initialization before start of printing
When the ON states of both the stack tray paper height sensor (S9) and stack tray
lower limit switch (SW2) are detected
• When paper is delivered
When the ON state of the stack tray lower limit switch is detected two successive
times because the height of the paper delivered to the stack tray has become lower
than the specified level
NOTE:
After the stack tray full state has been detected, a maximum of 50 sheets can be
stacked on the stack tray.
