Compensation for device aging |
摘要 |
Print quality is maintained by determining print conditions based on varying threshold values over the printhead lifetime before the print run. In particular, print conditions are determined through periodic quality adjustment cycles based on detected long-term and short-term temporal drift of print thresholds. A detector is provided to detect the presence or absence of ink being ejected from an inkjet printer. A sequence of eject and detect cycles over varying control conditions is performed to determine the minimum condition required to eject ink from the printer.
