摘要： A method and apparatus for servicing a pen in an inkjet printing device includes receiving a print job, determining a level of print quality required for the print job, detecting the operating characteristics of a number of nozzles to be used to print the print job; and, in the event that the operating characteristics of the nozzles are sufficient to meet the level of print quality, printing the print job. A maintenance procedure may be scheduled in the event that an individual one of the nozzles is not fully functional. In addition, the maintenance procedure may be scheduled to be performed during a time when the inkjet printing device is idle.

摘要： An inkjet printing device for printing plots comprises a printhead, which has a plurality of nozzles each nozzle having at least a working status and a failing status, a servicing unit capable of applying recovery functions to said plurality of nozzles, detection means for checking if a nozzles is in a working status or in a failing status, memory means and a plurality of functions executable by said device to improve image quality. Said memory means, responsive to said detection means, contains data on how the status of a nozzle is varying over time. Said device further comprises means to select and execute at least one of said plurality of functions, responsive to the data stored in said memory means. A method of improving image quality on plots produced by said device said method comprising the steps of: checking the status of one or more nozzles; storing in a memory support the status of a checked nozzle as detected during said checking step; and based on a plurality of said statuses stored over time in said memory support, performing an appropriate function form said variety for improving the image quality.

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。

摘要： An inkjet printing device for printing plots includes a printhead, which has a plurality of nozzles, and is capable of performing a variety of servicing functions. A method of recovering a printhead of this device includes: defining a set of causes of failures for said printhead; checking if one or more nozzles of the printhead are failing; identifying the cause of failure of a failing nozzle within said set, and, based on the identified cause of failure, performing an appropriate servicing function for recovering the failing nozzle
