Abstract

It is important to deposit a controlled amount of release fluid (i.e., silicone oil) on a fuser roll during standby. One way of accomplishing this is through puddling of the oil by means of a wick. The puddle size it has been found is quite sensitive to the load between the wick and the fuser roll. The load required for the run mode of operation would create a puddle size during standby which is too large and undesirable as it will adversely affect the wick and the fuser roll. In order to obviate the problem, the load between the fuser roll and the wick is reduced to a tolerable degree for standby from the value required for the run mode.

DUAL SETPOINT TEMPERATURE CONTROL FOR A NIP FORMING FUSER ROLL
John W. Trainor

Proposed Classification
U.S. C1. 432/60 Int. C1. F27b 9/28

This disclosure relates to controlling the temperature of a nip forming fuser roll. To this end, a dual setpoint is employed whereby the fuser surface temperature is controlled at a higher value during a standby mode than it is during a run mode. When the start print event occurs,...
