Laser ink-jet printhead i.e. single-row laser ink-jet printhead, for e.g. ink-jet printer, has optical transparent deflecting element comprising integral spacer on side facing substrate, and focusing laser beam via mirror element

摘要

The printhead (1) has an ink supply capillary (6) provided in flow connection with vaporizer capillaries (5) and ink output capillaries (7). An optical transparent deflecting element (3) i.e. hyperboloid shaped refractive surface, focuses a laser beam (2) via a fast-switching mirror element (12). An absorbent element is completely or partially pressurized on an inner wall of the supply capillary, and guides the laser beam to an ink curing part on a substrate. The deflecting element comprises an integral spacer on a side facing the substrate.
