Method to provide accurate fluid delivery

Abstract

A method for delivering a predetermined amount of fluid from a fluid ejection head. The method includes measuring one or more parameters selected from fluid flow parameters and electrical parameters for the fluid ejection head to provide one or more measured parameters; calculating a fluid ejection offset value from the one or more measured parameters; storing the fluid ejection offset value in a memory location on the fluid ejection head; accessing the fluid ejection offset value by an ejection head controller; and adjusting an amount of fluid ejected from the fluid ejection head during a fluid ejection step using the fluid ejection offset value to provide the predetermined amount of fluid from the fluid ejection head.
