METHODS AND APPARATUS FOR REDUCING THE PRINT-JOB COMPLETION TIME FOR A PRINTER HAVING AN INTERMITTENT-REFILL PRINTHEAD

Document Type and Number:

WIPO Patent Application WO2004096560

Kind Code:

A3

Abstract:

Methods and apparatus are disclosed for reducing the print-job completion time in a printing system having at least one printhead that is intermittently refilled from an "off-axis" ink supply during non-printing intervals. A reduced refill time is determined from an estimation of the amount of ink expended since the printhead was previously refilled, and on a characterization of the ink refill behavior of the printing system. The refill behavior of the printing system may be quantified in data stored in a memory device integral with a replaceable ink supply.
