摘要： The present invention is embodied in a system and method for optimizing the temperature operating range for a thermal inkjet printhead using pigmented ink over large print swaths. The printhead assembly includes connection and processing circuitry, a printhead body, ink channels, a substrate, such as a semiconductor wafer (commonly referred to as a die), a nozzle member and a barrier layer located between the wafer and nozzle member. The nozzle member has heating elements in arrays, as well as plural nozzles coupled to respective ink channels and is secured at a predefined location to the printhead body with a suitable adhesive layer. The printhead also includes a controller, which can be an integrated circuit processor, a printer driver, firmware or the like for controlling an increase in the mean temperature of the die through a feedback loop. The loop activates the heating elements and therefore increases the baseline temperature of the die before printing, and in turn decreases the temperature differential between the baseline temperature and the mean temperature of the die.

摘要： A method for determining service criteria for a printhead in a printer includes receiving an indication that service is needed, determining a calculated age of the printhead, and selecting a service procedure based on the determined calculated age. The selected service procedure has an impact on the long term life of the printhead that is proportional to the calculated age. The calculated age may be classified as a beginning of life phase, a middle of life phase or a maturity phase, and the service procedures may be selected such that the service procedure for the beginning of life phase has a low impact on the printhead's long term life, the service procedure for the middle of life phase has a moderate impact on the printhead's long term life, and the service procedure for the maturity phase has a severe impact on the printhead's long term life.
摘要翻译：一种用于确定打印机中的打印头的服务标准的方法，包括接收需要服务的指示，确定计算的打印头的年龄，以及基于所确定的计算年龄选择服务程序。所选择的服务程序对打印头的长期使用寿命有影响，该寿命与计算的年龄成正比。计算年龄可以分为生命阶段的开始阶段，生命阶段的中间阶段或成熟阶段，并且可以选择服务程序，使得开始使用阶段的服务程序对打印头的长期影响较小寿命期间，中间阶段的服务程序对打印头的长期使用寿命有一定影响，成熟期服务程序对打印头的长期使用寿命有重大影响。
