摘要： An environmental condition detection system for a hardcopy device, such as an inkjet printing mechanism, includes an environmental condition sensor having an optical property which changes in response to a change in an environmental condition, for instance humidity or temperature. The system also has an optical sensor which detects changes in the optical property and generates a signal for a controller that responds by changing an operating parameter of the hardcopy device. A hard copy device having such a environmental condition detection system is also provided, along with a method of determining an environmental condition within which a hardcopy device is operating.

摘要： An apparatus for detecting ink droplets ejected from ink drop generators has a target holder and a conductive absorbent target supported by the target holder. The apparatus for detecting ink droplets also has standoffs extending from the target holder. The apparatus for detecting ink droplets further has an actuator for moving the target holder towards the ink drop generators such that the standoffs space the target from the ink drop generators.

摘要： An inkjet printhead includes a nozzle plate formed of a polymer material that has been photoablated or photo-etched to form inkjet nozzles. The polymer material preferably is a plastic such as teflon, polyimide, polymethylmethacrylate, polyethyleneterephthalate or mixtures thereof. The nozzle plate also has formed in it a plurality of vaporization chambers. The inkjet nozzles are preferably formed in a flexible strip of polymer film by masked laser radiation, where the mask is physically spaced from the polymer film. Heater resistors may be formed on the nozzle plate within each of the vaporization chambers.

摘要： The invention is fault-tolerant dot-matrix printing that substitutes a tested functioning printing element for a malfunctioning printing element. A detector, such as a piezoelectric membrane drop detector, tests the printing elements for malfunctioning printing elements. Once a malfunctioning printing element is detected, either a detector or a substitution algorithm identifies which section of the printing elements the malfunctioning printing element resides in. The printer controller chooses a defect-free section to substitute for the defective section containing the malfunctioning printing element, disconnects the section containing the malfunctioning printing element, reroutes print signals from the defective section containing the malfunctioning printing element to the substitute section, and alters the scan path of the printhead so that the substitute section prints for itself as well as for the defective section.
