Abstract

This disclosure relates to xerographic copiers and printers. Disclosed is a control for sensing the degree of buckle in a copy substrate 8 which passes between a charge-retentive surface 10 and a roll fuser 12 as it moves across a baffle 14. The baffle is constructed such that a copy substrate such as plain paper is free to buckle as it passes thereacross. An electrical signal representing the degree of buckle is then used to vary the fuser speed. The signal is generated by means of a sensor 16 supported proximate the copy substrate. A signal generated by the sensor is compared in a controller 18 to a reference signal in order to generate an error signal which is used to control the speed of a fuser motor 20. Thus, if the buckle is severe, the fuser is speeded up.

SHORT PAPER PATH PROCESS CONTROL LOOP (Cont'd)

This disclosure relates to xerographic copiers and printers. Disclosed is a control for sensing the degree of buckle in a copy substrate 8 which passes between a charge-retentive surface 10 and a roll fuser 12 as it moves across a baffle 14. The

An electrical signal representing the degree of buckle is then used to vary the fuser speed. The signal is generated by means of a sensor 16 supported proximate the copy substrate. A signal generated by the sensor is compared in a controller 18 to a reference signal in order to generate an error signal which is used to control the speed of a fuser motor 20.
