Filed:

Jan 18, 2002

Appl. No.:

10/051892

Inventors:

Paul Mark Haines - Lebanon OR
James W. Ring - Blodgett OR
Gary D. Tarver - Corvallis OR

Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX

International Classification:

B41J 2175

US Classification:

347 93

Abstract:

An inkjet pen is disclosed having an interior chamber containing a pressure regulator. A filter within the interior chamber substantially surrounds the pressure regulator, providing a large filter surface area, and hence a low resistance to ink flow. The filter may be formed of a pleated filter material; the filter material may be retained by a rigid ink passage flange and a filter cap.

International Classification:

B41F 35/00
F26B 13/10

US Classification:

1014241, 34561

Abstract:

A method of predicting at least one drying parameter for a printing press includes estimating an amount and type of an ink to be deposited on a printing surface, determining at least one of: i) a type of the printing surface, ii) a thickness of the printing surface, and iii) a speed of the printing surface moving through the printing press, and calculating, via a controller associated with the dryer, the at least one drying parameter based at least on: i) the amount and the type of the ink to be deposited on the printing surface; ii) the type of the printing surface, iii) the thickness of the printing surface, and iv) the speed of the printing surface moving through the printing press. Also disclosed herein is a method of determining if the ink established on the printing surface is dry.
