Abstract

In a typical electrostatographic machine, an image is fused onto a substrate with a fusing device. Upon machine initiation, the device is "warmed up" to a preselected temperature. Commonly, an arrangement is provided for controlling the extent to which the fuser is warmed. This control arrangement is often triggered by an event, such as machine power-up. This approach of warming up the fuser with the machine is inefficient since virtually all of the components of the machine outside of the fuser have respective warm up times that are considerably shorter than that of the fuser. It would be desirable to provide a printing machine with a fuser that can be warmed up automatically in advance of intended machine usage, so that a user can obtain machine operation within a relatively short period of requesting operation at the machine.

FUSER WARM UP CALENDARKLOCK (Cont'd)

In a typical electrostatographic machine, an image is fused onto a substrate with a fusing device. Upon machine initiation, the device is "warmed up" to a preselected temperature. Commonly, an arrangement is provided for controlling the extent to which the fuser is warmed. This control arrangement is often triggered by an event, such as machine power-up. This approach of warming up the fuser with the machine is inefficient since virtually all of the components of the machine outside of the fuser have respective warm up times that are considerably shorter than that of the fuser.

Referring to the drawing, a fusing arrangement, according to the present disclosure, is designated with the numeral 10. The fusing arrangement 10
includes fuser 12, of the type, found in a Xerox 5090 printing system, a fuser control 14, and a user interface 16. The fuser control 14 includes a calendar/clock circuit 18, while the user int...
