Standard Practice for
Determining Toner Usage for Printer Cartridges1
《判定打印机碳粉消耗量的标准方法》
1.Scope
1．使用范畴
1.1This practice covers a procedure to determine the weight of toner ud for printing a single page derived from an electrophotographic process. The practice us a printer text target specifically developed for each printer for a page coverage of 5 6 0.5 % of the printable area. This practice requires specific tools and skills for disasmbling and reasmbling printer cartridges.
1.1此标准涵概了， 激光打印机在输出一页文档时， 测量碳粉消耗量的程序步骤。 此 方法操作规定每台打印机使用指定的打印文档， 且输出文档的页覆盖率为 5±0.5%。执 行操作时，需要特定的测试工具，且具备拆卸、重新组装碳粉盒的能力。
1.2The values stated in inch-pound units are to be regarded as the standards. The SI units given in parenthes are for information only.
1.2标准中数值的单位是英寸—镑。括号里的 SI 单位仅做参考 。
1.3This standard does not purport to address all of the safety concerns, if any, associated with its u. It is the responsibility of the ur of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to u.
1.3此标准主旨不是罗列所有的安全因素，而是联合它们的使用。此标准的使用人
有责任建立可靠适用性、健全的测试方法，并检测改进措施的适用性。

4.Summary of Practice
4.惯例摘要
4.1An electrophotographic printer utilizing an all-in-one supply cartridge is t up to determine the toner ud for a single page of print. A test page with 5 6 0.5 % text print output for the control cartridge is ud. 5 % text coverage of the printable area is the industry accepted average page coverage for office printers. The all-in-one cartridge is disasmbled to parate the toner hopper from the waste toner collection bin. The weight of the full toner hopper is measured. A specified number of prints are created on the printer using this cartridge and the weight of the ud toner hopper is measured. The toner ud for one print is calculated. In addition, the results can be ud to estimate the total page yield of the toner cartridge. A comparison can be made between the toner ud for the control cartridge and any other cartridge tested using this practice.
4.1准备一台已安装好一体式碳粉盒的激光印机，用来评测单页打印碳粉消耗量 。 覆盖率为 5±0.5%的文本测试页。 5%的文档覆盖率是行业公认的办公打印平均覆盖率。 一体式碳粉盒的粉仓可以从废粉仓中分离出来。先测量碳粉盒满粉仓的初始重量，打 印一定数量后，再称重此粉盒粉仓的重量。即可算出打印的粉耗量。另外，可使用此 粉耗量估测出整个碳粉盒的总页产量。使用此方法也可进行碳粉盒间的对比测试。

5.使用意义
5.1This practice can be ud for the evaluation of new and remanufactured toner cartridges and their respective components ud in an electrophotographic process.
5.1此方法可用于评估用于相同激光打印机的新碳粉盒和再填充碳粉盒。
5.2This test is suitable for rearch and development, and quality acceptance evaluations.
5.2此测试适用于新品开发和质量评估。

6.干扰因素
6.1Relative humidity can impact test results. The test should be performed at a controlled
temperature and humidity within the operating humidity range of the printer. This is usually between 20 and 80 % RH. All equipment, and materials should be conditioned in the same temperature and relative humidity for at least 24 h prior to testing.
6.1相对湿度可能影响实验结果。测试需要在把温度和湿度控制在打印机运行所允 许的湿度范围内进行，通常定为 20汶川大地震作文和 80%R。H在测试之前，所有的设备和物料必须在 此环境中放置至少 24 个小时。
梦见很多蜘蛛6.2In comparative cartridge test the same test target (data) and printer must be ud. The number of characters and the type of characters, font and font size have a direct affect on toner consumption.
6.2碳粉盒对比测试必须使用相同的测试样张和打印机，字符的数量和字符种类， 字体和字体大小都对碳粉消耗有直接影响。
6.3The test pattern should not produce uneven wear on the cartridge components as this will affect the test results.
6.3粉盒部件的磨损会导致测试样张打印不均匀，这样会影响测试结果。
6.4Printer related items such as the power supply, density control ttings, resolution enhancements, toner saver ttings, economy mode ttings, and lar optics may impact image quality and toner consumption.
6.4打印机相关的事项如：电源，密度设置，增强分辨率，节粉设置，经济模式设置 和激光都可能影响输出图像质量和粉耗量。
6.5Test printers should be in good mechanical and electrical condition. Preferably, printers with a continuous history of preventative maintenance should be ud. Any printer failures can invalidate the test.

7.2Printer Data System, capable of supplying a 5 6 0.5 % text page for the specific test printer bad on the control cartr idge (average original printer manufacturer ' s cartridge). This 5 6 0.5 % test target data can be created by printing text and determining the page coverage with a calibrated scanning or digital display device. Software and a co
mputer program to calculate the coverage will be required. The amount of text is changed and the process repeated until a 5 6 0.5 % coverage of the printable area is obtained. The printable area is 8 by 10 in. (0.203 by 0.254 m) making is usable for standard letter and A4 paper sizes. The specific test data must be created for each printer model and manufacturer.
