Description
The motor starts when you press the
execution key is present, and stops
when the stop key is pressed.
Automatically stops when execute is
selected.
The fan starts when the execution
key is pressed and stops when the
stop key is pressed.
Tray 2, 3 clutch stays on for 1
second and then automatically turns
off when execute is selected. The
main motor runs 2 seconds before to
check the clutch condition.
The PTL lights when the execute key
is pressed and stops when the stop
key is pressed.
The laser motor starts when the
execute key is pressed and stops
when the stop key is pressed.
The LSU motor starts and 'Laser
Ready' appears, if the motor spins at
the correct speed. Otherwise 'Laser
Error' is shown.
'Diode On' shows when the laser
diode is on. Otherwise, "Diode off" is
shown.
These show the current state of the
sensor.
This shows the current state of the
cover sensor. Touch the sensor to
confirm that the message changes
from "Cover Open" to "Cover
Closed".
These show the current state of the
sensor.
"Current Value" appears on the
upper line of the LCD. "Target Value"
appears on the bottom line.
(Target value is limited to between
80°-191° C.)
These functions ensure that the
HVPS is functioning correctly.
