any of the following conditions occurs:
●
BD failure
A specified BD interval is not detected within a specified period during the scanner motor drive.
●
Scanner motor start-up failure
The scanner motor does not reach a specified rotation within a specified period from when the
laser scanner starts driving.
●

interrupts optical path of the laser scanner when the cartridge door is open.
