Filed:

Dec 16, 2008

Appl. No.:

12/335591

Inventors:

Melissa Ann Monahan - Rochester NY, US
William Alexander Burton - Fairport NY, US
Paul M. Fromm - Rochester NY, US
Stephen Bradley Williams - Marion NY, US
Julie Marie Hanfland - Pittsford NY, US

Assignee:

Xerox Corporation - Norwalk CT

International Classification:

G03G 15/20

US Classification:

399 67, 399322, 399328

Abstract:

A method and apparatus for measuring nip width in an image production device is disclosed. The method may include receiving a signal to measure the nip width, the nip width being the distance of an arc length created by an intersection of a fuser roll and a pressure roll, positioning a nip width measuring device into the nip, measuring the nip width, determining if the measured nip width meets a required nip width, wherein if the measured nip width does not meet the required nip width, adjusting the nip width.

International Classification:

G03G 15/20

US Classification:

399 45, 399 67

Abstract:

A method and apparatus for adjusting nip width based on the measured hardness of a fuser roll in an image production device is disclosed. The method may include receiving an identification of media type, receiving a signal to measure fuser roll hardness, positioning a fuser roll hardness measurement unit onto the fuser roll, measuring the fuser roll hardness, and adjusting the nip width based on the measured fuser roll hardness and received media type identification.

Assignee:

XEROX CORPORATION - Stamford CT

International Classification:

G03G015/20

US Classification:

399328000

Abstract:

A reprographic marking device has two rolls, e.g., a pressure roll and a fuser roll, forming a nip. A drive motor moves the rolls in a continuous back and forth lateral motion to change the position of the rolls relative to a paper sheet passing through the nip portion.

International Classification:

B41J 11/44

US Classification:

400 76

Abstract:

A method and structure of automatically selecting replacement components for a printing machine automatically maintains media type statistics on media types used for printing in the printing machine for a period of time, and automatically recommends a replacement for a worn component with one of a plurality of interchangeable different-type replacement components based on the media type statistics. The interchangeable different-type replacement components have different performance characteristics for each of the media types, and the interchangeable different-type replacement components perform the same function as said worn component within the printing machine.
