US 11,904,598 B2 · Conditioners including conditioner shutdown

Abstract

A conditioner includes a pressure roller assembly, a tension roller assembly, a heating element, a pressure roller drive motor, a tension drive motor, and a controller. The heating element heats the pressure roller assembly. The pressure roller drive motor rotates the pressure roller assembly. The tension drive motor rotates the tension roller assembly. The controller receives a print job complete notification to initiate a conditioner shutdown. In response to the print job complete notification, the controller turns off the tension drive motor. The controller sets the heating element to a predetermined temperature and waits a first predetermined period. In response to the first predetermined period elapsing, the controller turns off the heating element. With the heating element turned off, the controller turns off the pressure roller drive motor.
