    • Detecting a fouled air filter in a computer equipment enclosure that includes an air filter, a supply plenum connecting the air filter and the computer equipment enclosure, a fan operating at a current fan speed, and a filter monitoring module connected for data communications to a management module. Detecting a fouled air filter according to embodiments of the present invention includes calculating, by the filter monitoring module, a pressure differential across the air filter; determining, for the current fan speed by the filter monitoring module in dependence upon a pressure differential profile for the air filter, whether the calculated pressure differential across the air filter exceeds a predetermined threshold value; and if the calculated pressure differential across the air filter exceeds the predetermined threshold value, reporting, by the filter monitoring module to the management module, that the calculated pressure differential across the air filter exceeds the predetermined threshold value.

    • A method is provided for detecting the type of print media provided to a thermal printer. A printer has a heat source disposed adjacent a temperature sensor to transfer heat upon activation across a portion of an introduced print media to the temperature sensor and a controller to receive a signal from the temperature sensor and to obtain a temperature signature generally identifying attributes of the introduced print media and to adjust print head settings in response to the identified attributes. The printer may further comprise a sensor to detect access to a print media storage compartment and to initiate examination of the heat transfer properties of the introduced print media upon detecting that the print storage compartment has been accessed.
    • 提供了一种用于检测提供给热敏打印机的打印介质的类型的方法。 打印机具有设置在温度传感器附近的热源,以在激活时将热量传递到引入的打印介质的一部分到温度传感器,以及控制器,以接收来自温度传感器的信号,并且获得温度特征, 引入打印介质并根据识别的属性调整打印头设置。 打印机还可以包括传感器,用于检测对打印介质存储隔间的访问,并且在检测到已经访问了打印存储隔间时,开始检查引入的打印介质的传热特性。
