Abstract
Methods and apparatus provide for automatic fluid ejector alignment and performance evaluation and modification in one or multiple planes. A fluid ejector fires a drop through a drop detection module. A signal indicating drop presence or absence is sent to a computer. The computer analyzes the data, and makes a compensation determination of a preferred method of using the fluid ejector. The compensation determination may include electronically modifying the image data to be printed, physically manipulating the fluid ejector, completely skipping the fluid ejector during printing operations, or in some other way modifying the fluid ejector or image data such that apparent printed image error due to fluid ejector alignment or performance error is reduced.
