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.
