The main motor starts when the execution key is pressed
and stops when the stop key is pressed.
Automatically stops, when the execution is chosen.
stops, when the execution is chosen.
The fan starts when the execution key is pressed and
stops when the stop key is pressed.
The tray2,3 clutch is on for 1sec and then it automatically
stops, when the execution is chosen.On this function,
the main motor runs before 2sec from the point of the
clutch
on in order to check the clutch state.
PTL (Pre-Transfer Lamp) is lights when the execution key
chosen and it stops when the stop key is chosen.
The laser motor starts when the execution key is pressed
and stops when the stop key is pressed.
The LSU motor starts and "Laser Ready" is displayed if
the motor spins at the correct speed, otherwise "Laser
Error" is displayed.
"Diode On" is displayed, when the laser diode is on.
Otherwise "Diode Off" is displayed.
These functions allow the current state of the sensor to be
displayed.
This function allows the current state of the Cover sensor
to be displayed. Touch the sensor and confirm that the
message changes: "Cover Open" to "Cover Close"
These functions allow the current state of the sensor to be
displayed.
"Current value" is displayed on the upper line of the LCD,
and "Target value" on the bottom line.
Target value is limited from "191°C" to "80°C"
These Functions are provided to check whether the
control of the HVPS is functioning correctly.
