Abstract
A roller for contacting print media in an image forming device includes a tubular core formed of a first material and having an inner surface and an outer surface, and a sleeve formed of a second material and surrounding a portion of the tubular core. The sleeve includes an inner portion surrounding a portion of the inner surface of the tubular core and an outer portion surrounding a portion of the outer surface of the tubular core. The outer portion of the sleeve has an outer surface for contacting the print media. As such, contact of the print media with the roller is made by the outer portion of the sleeve when the print media is routed through the image forming device.
Claims32
A roller used for contacting print media in an image forming device, the roller comprising:
- a tubular core formed of a first material and having an inner surface and an outer surface;
- and
- a sleeve formed of a second material and surrounding a portion of the tubular core,
- wherein the sleeve includes an inner portion surrounding a portion of the inner surface of the tubular core and an outer portion surrounding a portion of the outer surface of the tubular core.
A method of forming a roller for an image forming device, the method comprising the steps of:
- providing a tubular core formed of a first material and having an inner surface and an outer surface;
- and
- surrounding a portion of the tubular core with a sleeve formed of a second material, including surrounding a portion of the inner surface of the tubular core with an inner portion of the sleeve and surrounding a portion of the outer surface of the tubular core with an outer portion of the sleeve.
A print media transport assembly, comprising:
- a shaft;
- and
- at least one roller mounted on the shaft the at least one roller including a tubular core, an inner sleeve surrounding a portion of an inner surface of the tubular core, and an outer sleeve surrounding a portion of an outer surface of the tubular core, wherein the tubular core is formed of a first material and the inner sleeve and the outer sleeve are formed of a second material, and wherein the inner sleeve contacts the shaft.
An image forming device, comprising:
- at least one print media transport assembly used for routing print media through the image forming device,
- wherein the at least one print media transport assembly includes a shaft mounted in the image forming device and at least one roller mounted on the shaft, the at least one roller used for contacting the print media and including a tubular core, an inner sleeve surrounding a portion of an inner surface of the tubular core, and an outer sleeve surrounding a portion of an outer surface of the tubular core, wherein the tubular core is formed of a first material and the inner sleeve and the outer sleeve are formed of a second material, and wherein the inner sleeve contacts the shaft and the outer sleeve is used for contacting the print media.
