Filed:

Mar 2, 2011

Appl. No.:

13/038880

Inventors:

Larry M. Ernst - Longmont CO, US
Michael J. Holley - Broomfield CO, US

John C. Wilson - Longmont CO, US

International Classification:

B41J 29/393

US Classification:

347 19

Abstract:

Methods and systems herein provide for print data compensation for a print head based on a lateral offset of a media relative to the print head. In one embodiment, a print controller of a printer identifies an edge of a media that is parallel to a direction of travel of the media, and determines a lateral offset between the edge of the media and a print head of the printer. The print controller then modifies data for the print head based on the lateral offset to compensate for a lateral motion of the media relative to the print head.

US Classification:

358 115

Abstract:

Methods and systems herein provide for estimating when the print quality of a printer is expected to decrease below a threshold based on a function of change in the print quality of the printer. In one embodiment, a system calculates a plurality of print quality measurements based on pages printed by a printer. The system determines a function of change of the print quality of the printer that is based on changes in the print quality measurements. The system estimates when the print quality of the printer is expected to decrease below a threshold based on the function of change in the print quality of the printer. The system then provides the estimate to a print operator.
