Carousel
Rotation
Failure
When the following phenomena are detected by the toner carousel posi-
tion sensor (PS4), the DC controller is notified by the mechanical
controller and judges them as carousel rotation failures. The DC
controller notifies the I/O controller of the faults and stops the printer.
• PS4 does not detect the rotational position flag even though the
toner carousel motor rotates.
• PS4 detects an error in the width of the rotational position flag.
• PS4 detects a flag width differing from that of the specified rota-
tional position flag.
• PS4 does not detect the rotational position flag when the press oper-
ation starts.
Cartridge
Press/
Separation
Failure
When the following phenomena are detected by the toner cartridge
position sensor (PS3), the DC controller is notified by the mechanical
controller and judges them as toner cartridge press/separation failures.
The DC controller notifies the I/O controller of the faults and stops the
printer.
• PS3 stays on for a certain period of time after press starts.
• PS3 stays off for a certain period of time after separation starts.
