Filed:

Jun 27, 2008

Appl. No.:

12/147663

Inventors:

Patrick Oscar Bischel - Paris KY, US
Michael Duane Donovan - Lexington KY, US
Kevin Dean Schoedinger - Lexington KY, US

Assignee:

Lexmark International, Inc. - Lexington KY

International Classification:

B41J 2/435

US Classification:

347262, 347264

Abstract:

A system and a method for improving total job time without needing to know a job size. An engine dynamically decides which process speed to warm up to based on a number and size of pages currently submitted to the engine, and thus deliver the best job time dynamically. The engine also takes into account its condition and a condition of a fuser, and dynamically selects a substantially optimum point of operation.

Filed:

Dec 21, 2004

Appl. No.:

11/017995

Inventors:

Michael Donovan - Lexington KY, US

International Classification:

B41J 29/393

US Classification:

347019000

Abstract:

A method for forming a combined printhead alignment pattern includes printing a row of spaced blocks which accommodates both the collection of multiple printhead alignment data pertaining to printhead alignment as between a plurality of printheads and the collection of bi-directional alignment data pertaining to bi-directional alignment for at least one particular printhead, each of the blocks being printed in a single scan direction, but with some of the blocks being printed in a first scan direction and a remainder of the blocks being printed in a second scan direction opposite to the first scan direction.

Appl. No.:

13/554749

Inventors:

Jichang Cao - Lexington KY, US
Michael Duane Donovan - Lexington KY, US
Douglas Campbell Hamilton - Lexington KY, US

International Classification:

G03G 15/20

US Classification:

399 69

Abstract:

A printer is provided having a fuser assembly having a belt, a heater to heat the belt, a backup roll positioned to engage the belt thereby defining a fusing nip with the belt, a main temperature sensor associated with the heat transfer member, the first temperature sensor associated with the backup roll for sensing a temperature of a portion of the backup roll, the second temperature sensor associated with a distal end region of the heat transfer member for sensing the temperature of the distal end region. A controller is coupled to the fuser assembly for controlling a throughput of the printer based on at least one of the backup roll temperature and the temperature at the distal end region of the heater.
