Abstract
Disclosed herein are several embodiments to facilitate the characterization of fuser stripping performance. Recognizing that the characteristics of a substrate exiting a fusing nip are indicative of the operation of the nip and the stripping operation itself, several contact and non-contact sensing methods are described to detect or predict degraded stripping performance, thereby permitting one or more compensation techniques to be employed, or to identify the need for fuser subsystem replacement.
Claims20
A method for monitoring stripping performance in a substrate nip, comprising:
- detecting, after separation of at least a lead edge of the substrate from rolls forming the substrate nip, at least one characteristic indicative of the separation of a substrate from the nip and generating a signal representing the at least one characteristic;
- and
- adjusting, in response to the signal, at least one of a plurality of parameters related to the substrate nip to alter the at least one characteristic indicative of the separation of the substrate.
A method for monitoring stripping performance of a fuser in a xerographic printing machine, comprising:
- detecting, after separation of at least a lead edge of the substrate from rolls within the fuser, at least one characteristic indicative of the separation of a substrate from the fuser and generating a signal indicative thereof;
- and
- adjusting, in response to the signal, at least one of a plurality of parameters related to the fuser to alter the at least one characteristic indicative of the separation of the substrate.
A printing system in which a toner image is fused to a substrate sheet in a fuser, comprising:
- a sensor for monitoring, after separation of at least a lead edge of the substrate sheet from rolls in the fuser, at least one of a plurality of parameters indicating separation of the substrate sheet from the fuser and generating a signal indicative thereof;
- and
- a controller, responsive to the signal, for adjusting at least one of the plurality of parameters effecting separation of the sheet from the fuser.
