|The "page yield" is best described as the number of pages a printer can print from a single ink cartridge and can be an important and deciding factor when it comes to which inkjet, photo/office all-in-one, or inkjet fax to purchase. Canon aims to provide its customers with fair, honest and meaningful data regarding page yields and running cost comparisons.
The quoted page yield for a given sample document is based on an average of three identical printers printing each document continuously until the ink runs out. This is done three times per printer, using a new set of cartridges each time.
What Affects Page Yield?
Many different variables have to be taken into account when measuring page yield:
Canon's testing keeps these variables constant to ensure that yields are comparable between different printers.One Way of Measuring Across Brands, for Easy Comparison
For people to be able to compare page yields between different printers and manufacturers, there needs to be one industry-wide testing methodology. Currently, Canon is working with other manufacturers and the International Organization for Standardization (ISO) to establish this international standard. It is expected to be ratified and published by the end of 2006.
The page yields on this website were measured already according to the emerging ISO inkjet yield standards.
Standard Testing Documents, Standard Settings
To determine page yields, a set of standard sample documents is used. These standard test documents are designed to represent the documents and photographs printed by a typical user.
The same set of documents is used to determine yields for each printer model. The software used and driver settings are also standardized per document type. When testing, the inks are used immediately after they are unsealed and printing is done continuously. This way the yields quoted are a reliable reflection of actual page yields.
