International Classification:

B41J002/01
US Classification:

347101, 347103, 347 96
Abstract:

An apparatus for ink-jet printing including an ink-jet print head to jet ink, a coating solid, and a coating holder to support the coating solid, wherein the coating holder transfers a portion of the coating solid onto a medium to form a coating solid layer. The coating holder and coating solid may be combined in a removable cartridge. In addition, the medium may be an intermediate transfer medium, a media support medium, a transfer medium, or media, such as paper. A method for inkjet printing also includes applying a coating solid to a medium to form a layer of the coating solid, in a solid form, having predetermined thickness, and applying ink to the medium. The layer of coating solid may interact with the applied ink to destabilize colorant in the ink.

G03G 15/08
US Classification:

399284, 399274, 399264
Abstract:

A device to regulate toner within an image forming apparatus. The regulating member has a first section and a toner regulating edge with at least one gap. The regulating member controls the amount of toner that is distributed on the surface of the toner developer roller by contacting the toner developing roller in a contact region. The gap, having at least one upper edge, may regulate toner on the toner developer roller near the contact region. The toner regulating device may prevent inadvertent toner marks that may appear on printed media.

US Patent:

7912400, Mar 22, 2011
Filed:

Sep 18, 2007
Appl. No.:

11/856818

Assignee:

Lexmark International, Inc. - Lexington KY
International Classification:

G03G 15/16
US Classification:

399101
Abstract:

The present application is directed to devices and methods for removing toner from a belt within an image forming apparatus. In one embodiment, the device includes a housing that forms an enclosed interior space. The housing may include an inlet that leads into the interior space. A blade may be positioned in proximity to the inlet to remove the toner from the belt and direct it into the inlet. An auger may be rotationally positioned within the interior space to move the toner along a longitudinal width of the device. An agitating member may be rotationally positioned within the interior space to move the toner from the inlet towards the auger. The agitating member may include a flexible arm that contacts against at least one of the blade and the auger during rotation.
