Cost Per Print
Cost Per Page The printer industry seems to be converging on a standard for determining cost per page, leading to the possibility of finally being able to compare running costs. But we're not there yet. When you compare claimed costs, be sure to check what method the claims are based on, and don't take comparisons based on different methods too seriously.There are at least three common ways to determine cartridge yield for calculating a monochrome cost per page: 5 percent per page coverage; the ISO/IEC 19752 test suite; and the ISO/IEC 24712 test suite. They all give different results. Color Cost Per Page There are at least two common ways to determine cartridge yield for calculating a color cost per page: 5 percent coverage with each color and the ISO/IEC 24712 test suite. Again, they give different results. Is Black a Color? Some manufacturers leave black out of the calculation for color pages. It should be included, since most color pages (other than photos) use black too. Cost Per Page or Cost of Toner? Most laser printers use other consumables besides toner (also known as routine maintenance items)-things like fusers and transfer rollers. The actual total cost per page includes those items too. Without them, the manufacturer is just giving the cost of the toner. The Five Percent Non-Solution Cost per page claims based on 5 percent coverage (or 5 percent per color) need to be taken with a large grain of salt even when you compare them to each other. Unlike the ISO/IEC yield testing, there's no standard procedure for determining things like end of life for a cartridge, so results from different manufacturers aren't really comparable.
