Co-Extruded Tubing For An Off-Axis Ink Delivery System

View page
US Patent:
6557987, May 6, 2003
Filed:
Sep 25, 2000
Appl. No.:
09/669620
Inventors:
Alan Shibata - Camas WA
Alan Biggs - Vancouver WA
Lap Thai Nguyen - Vancouver WA
John Michael Kniffin - Wilsonville OR
Paul L. Nash - Monmouth OR
Yi Liu - Corvallis OR
Gerald A. Mello - Albany OR
Ah Chong Johnny Tee - Singapore, SG

Assignee:
Hewlett-Packard Development Company, L.P. - Houston TX
International Classification:
B41J 217
US Classification:
347 84
Abstract:
A fluid transport conduit for conveying ink-jet ink from a reservoir to a printhead in an ink-jet printer is provided. The fluid transport conduit comprises at least one inner layer, such as high density polyethylene, cyclic olefin copolymer, or polypropylene homopolymer, that is flexible and is a barrier to liquids, and at least one outer layer, such as nylon or polyvinyl alcohol, that is a barrier to air and is softer, or more compliant, than the inner layer, with the inner layer bonded to the outer layer. The two layers are advantageously co-extruded to form the fluid transport conduit.

Flipping Wiper Scraper System For Inkjet Printheads

View page
US Patent:
6561619, May 13, 2003
Filed:
Jan 31, 2000
Appl. No.:
09/495010
Inventors:
Alan Shibata - Camas WA
Todd R. Medin - Vancouver WA
John A. Barinaga - Portland OR
Dean A. Gaylor - Vancouver WA
Le Pham - Vancouver WA
Michael S. Millman - Vancouver WA
Tanya V. Burmeister - Vancouver WA
Assignee:
Hewlett-Packard Company - Palo Alto CA
International Classification:
B47J 2165
US Classification:
347 33
Abstract:
A flipping wiper scraper system for cleaning several inkjet printheads in an inkjet printing mechanism has a wiper support mechanism which moves several elastomeric wipers across the printheads to wipe off accumulations of ink residue. This ink residue is then scraped off of the wipers to ready them for the next wiping stroke using a scraper system. The wiper support mechanism inverts the wipers to engage scraper bars of the scraper system. The scraper bars have scraping heads and capillary channels to draw liquid ink residue away from the heads through capillary forces. The scraper bars are arranged so only one or two wipers are scraped at any given time to reduce noise and quiet overall unit operation. A method of cleaning an inkjet printhead, along with an inkjet printing mechanism having such a flipping wiper scraper system are also provided.
