The IPTU driver controls the operational sequence of the IPTU and the serial communication with the DC controller of the product. The DC controller sends several commands to the IPTU driver at specific times. The IPTU driver drives the motors according to the commands. The IPTU driver sends the status information of the IPTU to the DC controller. The DC controller determines if there is an IPTU illegal connection. The DC controller notifies the formatter if it does not control the serial communication with the IPTU driver when the product is turned on, when it is recovering from Sleep mode, or during the prerotation period when the door closes. The printer supplies DC24V to the IPTU. The IPTU driver generates DC3.3V for sensors and ICs based on the DC24V.
