摘要： A method and apparatus for detecting the end of life of a print cartridge for a thermal ink jet printer determines the status of the print cartridge and warns the user if the print cartridge is at or near the end of its useful life. In a first mode of operation, an initial temperature of a printhead contained in the print cartridge is checked after a threshold amount of ink is expelled from the printhead, such as for a high density print swath or during a service routine. This initial temperature is then compared with a maximum initial temperature. If the initial temperature exceeds the maximum initial temperature, a warning about the status of the print cartridge is sent to a user. If the initial temperature does not exceed the maximum initial temperature, the user is informed of the remaining life portion of the print cartridge. In a second mode of operation, a final temperature is checked after a period of time elapses since the threshold amount of ink is expelled from the printhead. This final temperature is then compared to a maximum final temperature. If the final temperature exceeds the maximum final temperature, a warning about the status of the print cartridge is sent to a user. If the final temperature is less than the maximum final temperature, the user is informed of the remaining life portion of the print cartridge. In a third mode of operation, the heat transfer efficiency of the print cartridge is calculated. If the heat transfer efficiency of the print cartridge is below a minimum heat transfer efficiency, a warning about the status of the print cartridge is sent to a user. If the heat transfer efficiency exceeds a minimum heat transfer efficiency, the user is informed of the remaining life portion of the print cartridge.

摘要： A high-durability printhead for an ink cartridge printing system. The printhead includes a substrate having ink ejectors (e.g. resistors) thereon and an orifice plate positioned above the substrate. The orifice plate (which preferably involves a non-metallic polymer film) has a top surface, bottom surface and a plurality of openings therethrough. To improve the durability of the orifice plate, a protective coating is applied to the top surface and/or the bottom surface of the plate. Representative coatings involve dielectric compositions (including diamond-like carbon) or at least one layer of metal. This approach improves the abrasion and deformation resistance of the plate and avoids "ruffling" and "dimpling" problems.

摘要： An inkjet printing system includes a replaceable printhead having plural nozzles for ejecting ink droplets, a service station for capping and wiping the plural nozzles, and a replaceable ink cartridge housing a supply of ink and further including a cartridge memory for recording service station-control data. A processor is coupled to the ink cartridge memory and is responsive to service station-control data read from the cartridge memory to derive a service station control value. The printhead further includes a memory which records printhead-related parameters, and the processor is responsive thereto and service station-control data read from said cartridge memory to control the service station. The control data may be service station parameters, one or more subroutines to control the service station and combinations thereof.
