Appl. No.:

12/346989

Inventors:

Donald Paul McCoy - Georgetown KY, US
Mark Connelly Ott - Lexington KY, US
David Charles Weatherly - Versailles KY, US

Assignee:

Lexmark International, Inc. - Lexington KY

International Classification:

B41J 23/00

US Classification:

347 38

Abstract:

A rotary inkjet imaging apparatus includes a carrier movable bi-directionally along a linear guide path defined adjacent to a curved print zone and extending parallel to a longitudinal axis thereof, and an inkjet printhead disc having a body and at least one and preferably multiple printhead chips integrated into its perimeter. The disc body is supported by the carrier for undergoing movement within the curved print zone along a curved path winding about a central axis extending parallel to the guide path and coaxial with the longitudinal axis of the curved print zone such that the disc body moves about the central axis multiple revolutions and the printhead chips print on the page concurrently as the carrier unidirectionally moves along the linear guide path and the disc body moves within the curved print zone and through portions of the curved path in which the chips face toward the page.

International Classification:

B41J 2/135

US Classification:

347 44, 347 37, 347 67

Abstract:

A micro-fluid ejection device defines a print gap from an ejection head to a print media. An ejection zone of the head ejects fluid across the print gap during use. At least one wind baffle adjacent the ejection zone modifies airflow in the print gap as the head scans. In various designs, multiple wind baffles reside on either sides of the ejection zone to provide a cascading airflow effect from one wind baffle to the next. Baffle shapes, spacing and locations define multiple embodiments.

US Classification:

347 38

Abstract:

A rotary inkjet imaging apparatus includes a curved print zone having a longitudinal axis and in which a page of media is held in a curved configuration at a stationary position, a carrier movable bi-directionally along a linear path defined adjacent to the curved print zone and extending parallel to the longitudinal axis thereof, and at least one inkjet printhead supported by the carrier for undergoing movement within the curved print zone along a curved path winding about a central axis extending parallel to the guide path and coaxial with the longitudinal axis of the curved print zone such that the inkjet printhead moves about the central axis multiple revolutions and prints on the page concurrently as the carrier unidirectionally moves along the linear path and the printhead moves within the curved print zone and through portions of the curved path in which the printhead faces toward the page.

US Classification:

347 37

Abstract:

Disclosed is a system for regulating airflow velocity in a print gap region of a micro-fluid ejection device. The system includes a carrier member configured to carry an ejection head therewithin; a nozzle array configured at a bottom portion of the ejection head; and a channel member extending from a top portion of the carrier member and along a depth of the carrier member up to the bottom portion of the ejection head. Also, the channel member extends along at least a width of the nozzle array. Additionally, the channel member is configured to receive a flow of air through a slot configured at the top portion of the carrier member and to direct the flow of air from the top portion of the carrier member towards the bottom portion of the ejection head. Further disclosed is another system for regulating airflow velocity in a print gap region.

Abstract:

A wide area printer is capable of printing large images on non-typical surfaces such as pavement, grass, or soil. The printer is a wheeled device that is capable of multiple configurations including a plurality of drop nozzle arrays and a plurality of spray nozzle arrays. Each nozzle is independently addressable. Alternately, a group of nozzles may be addressed simultaneously. Each array of nozzles contains a carrier and a colorant. The colorant may be pre-mixed in the carrier, or may be mixed in-situ.
