Apr 21, 2004

Appl. No.:

10/828902

Inventors:

Larry W. Acton - London KY, US

Assignee:

Lexmark International, Inc. - Lexington KY

International Classification:

B65H 3/44

US Classification:

271 905, 271 906, 271 911, 271 912, 347104

Abstract:

An imaging apparatus includes a printhead carrier system including a printhead carrier configured for movement along a scan path, a first sheet picking mechanism, a second sheet picking mechanism, and a selector device. The selector device is configured to select one of the first sheet picking mechanism and the second sheet picking mechanism for picking a sheet of print media based on a position of the printhead carrier.

International Classification:

B65H 29/20

US Classification:

271314, 188 67

Abstract:

The present invention includes a damping device for a media feed mechanism for a peripheral device having a media feedpath having a feed shaft and a downstream exit shaft. In one form a damping hub is mounted on said exit shaft, a resilient biasing member extending between the damping hub and the feed shaft to create a damping force on the damping hub. In another embodiment damping is provided by a brake structure engaging said damping hub. In yet another embodiment, a brake structure is pivotably mounted.

Appl. No.:

10/310762

Inventors:

Larry Acton - London KY, US
William Connors - Lexington KY, US

International Classification:

B65H005/22

US Classification:

271/010090

Abstract:

An imaging apparatus includes a motor including a motor shaft to which a pinion gear is attached, and a feed roller including a shaft. The feed roller is positioned upstream from the print zone in relation to the sheet feed direction. A primary gear train includes a first gear in mesh with the pinion gear and a second gear rigidly mounted to the shaft of the feed roller. A spring coupling has a first end connected to the second gear of the primary gear train. A secondary gear train includes a third gear in mesh with the pinion gear and a fourth gear rotatably mounted to the shaft of the feed roller for free rotation with respect to the shaft, the second end of the spring coupling being connected to the fourth gear of the secondary gear train.

US Classification:

271273000

Abstract:

An apparatus for varying nip pressure in a media feedpath including a feed roller and a pressure roller defining a feed nip there between includes a rotatable cam having a preselected eccentric path when rotated, a first pivotable linkage pivotally engaging the rotatable cam, a second pivotable linkage, a biasing member operably interconnecting the first and second pivotal linkages for providing a biasing force on the pressure roller. The pressure roller is rotatably connected to the second linkage opposite the biasing member, wherein rotation of the cam varies the biasing force provided by the biasing member on the pressure roller.
