摘要： A fixing device has a fixing unit and a temperature detection unit. The fixing unit includes a heat roller provided with a roller section and a heater section, and a pressure roller in pressure contact with the heat roller. These rollers are disposed in a protective cover. The roller section includes a base layer of aluminum formed into a hollow cylindrical shape, a black radiation layer, and a toner parting layer. The heater section is disposed in a hollow space of the base layer. In this heat roller, when heat is emitted from the heater section, and the heat is transmitted to the radiation layer via the base layer, greater amount of infrared radiation is emitted from the radiation layer than in the case of a heat roller that is not equipped with the radiation layer. The temperature detecting unit includes an infrared radiation sensor. Thus, even if a noise component is absorbed to some extent by locating the sensor at a distance from the heat roller on an outside of the protective cover, the temperature of the heat roller is detected accurately.

摘要： A color blindness dialog box in a Properties window includes a color blindness process mode checkbox enabling a user to select a printing process designed for color blindness. When the color blindness process mode checkbox is checked, it is determined whether the image to be printed includes problematic areas for people with color blindness. If so, image data for these areas is extracted and displayed in a popup window. Subsequently, a borderline process is performed to form a borderline on either or both of the border areas and of text data and graphics data. Thus, the problematic areas are extracted and processed properly so that the problematic areas will become easy to distinguish.

摘要： A system of printers uses replicable toner boxes, which each has a unique serial number. Each printer determines once the toner box is empty. At this time, the printer registers the serial number of the used toner box in used toner box list in a memory. Each time a toner box is mounted in the printer, the printer reads and compares the serial number of the freshly inserted toner box with the serial numbers in the list in the memory. If the serial number of the presently mounted toner box matches any in the list, this means that the toner box has previously been judged to reach life end, so the printer displays a message that the toner box is not suitable for use in the printer and prevents further printing operations until the toner box is replaced with a new one.
摘要翻译：打印机系统使用可复制的墨粉盒，每个墨盒都具有唯一的序列号。墨粉盒一旦空了，每个打印机就会确定。此时，打印机将用过的碳粉盒列表中的二手碳粉盒的序列号注册到存储器中。打印机每次安装墨粉盒时，打印机会将新插入的墨粉盒的序列号与存储器列表中的序列号进行比较。如果目前安装的墨粉盒的序列号与列表中的任何一个相符，这意味着以前已经判定墨粉盒已达到使用寿命，因此打印机将显示一个消息说，墨粉盒不适合在打印机中使用，防止进一步的打印操作，直到更换新的墨粉盒。
