US Patent:

6810229, Oct 26, 2004

Filed:

Dec 30, 2002

Appl. No.:

10/331519

Inventors:

Larry Christopher Coleman - Lexington KY

Assignee:

Lexmark International, Inc. - Lexington KY

International Classification:

G03G 1520

US Classification:

399323

Abstract:

An improved fuser subassembly is provided for electrophotographic printers, in which the detack fingers that separate print media from the fuser hot roll do not make physical contact with that hot roll, and thus are ânon-contactâ detack fingers. A maximum clearance distance is observed as a relatively tight tolerance between the surface of the hot roll and the tip of the non-contact detack fingers. Both color and mono laser printer products can benefit from this design. Since the finger tips are spaced-apart from the fuser hot roll, the life of the hot roll is increased, and other potential problems are eliminated, such as contamination of the detack fingers, which sometimes cause accordion jams of prior art âcontactâ detack fingers.

Assignee:

Lexmark International, Inc. - Lexington KY

International Classification:

G03G 15/20

US Classification:

399322

Abstract:

An apparatus and method are provided for the reduction of wrinkles formed in sheets of paper media which may contain various levels of absorbed moisture across the surface and which are processed through a fuser section of a printing or copying device. Protruding features may be provided laterally spaced apart by a desired paper width at the fuser nip to create a pressure contact area which constrains the outer longitudinal edges of the sheet of paper as it enters the nip.
