As the guide outlines there is no guarantee that in your use of the device you will get exactly the yield that is shown for a given toner cartridge.  This is due to the variability of the design of printed documents and the variability of how any printer gets used in the field.  Rated yields do however give a reasonable estimate of what you could expect and can help you compare the relative cost of one device with another. **The biggest impact on yield is average page coverage.**  Ratings for most products are done at 5% coverage using a standard ISO page so that the variability of page type is removed from the equation.  Most users don't take into account however how much a small increase in coverage can impact yield.  If your average page coverage was 8% then you have increased your coverage by 60%.  Thus if a cartridge was rated at 5000 pages at 5% you would only be able to expect 3000 pages to be yielded at 8%.  [In a recent article I analysed a case from one of our clients where coverage had a massive impact on their operating costs.](https://blog.leppert.com/office-document-strategies-blog/bid/58200/My-Service-Rate-For-My-Colour-MFP-is-Too-High) Understanding the costs of operation of your office printers before you buy is an important component of a purchase decision. ## Have you been surprised by how costly your printers can be to run?  Have you had any good experiences with cost effective office printer operation? ***Lee K*** ## ***[![8 Step Guide to Choosing Your Multifunction Printer](https://www.leppert.com/hs-fs/file-15650051-jpg/images/8_step_guide_to_choosing_your_multifunction_printer.jpg)-8 Step Guide to Choosing Your Multifunction Printer ](https://www.leppert.com/free-8-step-guide-to-choosing-your-multifunction-printer/) *** Topics: [Multifunction Printer](https://www.leppert.com/office-document-strategies-blog/topic/multifunction-printer), [Printer](https://www.leppert.com/office-document-strategies-blog/topic/printer), [toner](https://www.leppert.com/office-document-strategies-blog/topic/toner), [cost of printing](https://www.leppert.com/office-document-strategies-blog/topic/cost-of-printing) ### Office Document Strategies ### ![Computer network](https://www.leppert.com/hs-fs/file-15667396-jpg/images/images-resized-164.jpg?width=178&height=145&name=images-resized-164.jpg) This blog discusses ways to optimize and improve the management and production of documents used in your business.  Business documents and their content - whether paper or electronic, are the repository of corporate knowledge which underpins all of the functions of commerce.
