Appl. No.:

10/256963

Inventors:

Dheya Alfekri - San Diego CA, US
Minh C. Duong - San Diego CA, US

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

B41J002/01

US Classification:

347102, 347100, 347101

Abstract:

An apparatus and method of thermal inkjet printing is provided. The apparatus is adapted to be used with an inkjet ink including a pigment(s), an aqueous vehicle, and a sufficient amount of polymeric binder and/or humectant(s) to wet and directly adhere to non-porous, uncoated, untreated, hydrophobic media. The ink is adapted to be ejected through a thermal inkjet head with consistent image quality and no kogation. The concentration of binder and/or humectant(s) raises the viscosity of the ink at room temperature. As such, the apparatus is adapted to lower the viscosity of the ink prior to the ink being ejected through the thermal inkjet printhead. Additionally, the apparatus is adapted to prepare the media for receiving the ink, and dry the ink after the ink is deposited on the media. This can be accomplished by providing heat to the media and/or the ink during the printing process.

International Classification:

B65H 1/02
B65H 3/34

US Classification:

271149, 271145, 271167

Abstract:

This invention relates to an input tray media de-slouch apparatus, comprising; an input media tray, at least one pivotable media de-slouch arm operatively connected to the tray, and a releasable locking means operatively connected to the arm and the tray to lock the arm prior to media being placed against the arm to substantially keep the media from slouching and to release the arm when the media is being fed from the input tray.
