Method of driving and controlling ink jet print head, ink jet print head, and ink jet printer |
摘要 |
An increase in variation in resistance value resulting from a reduction in thickness of heaters is dealt with without increasing the manufacture costs of the print head, by allowing smaller ink droplets to be efficiently ejected. A setting for a pulse voltage is essentially varied depending on the ejection threshold energy of the head is employed so that optimum drive power conditions can be reasonably set over a range of varying resistance values resulting from differences among manufactured print heads. This provides a print head and a printing apparatus which can deal with an increase in differences among manufactured heads by allowing smaller ink droplets to be efficiently ejected without reducing the yield of manufactured print heads.
