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:
- Content and type of document printed
- Type of paper used
- Type of printer
- Print mode and driver setting
- Software application used
- Conditions such as ambient temperature, humidity and frequency of printing
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. Canon has worked with other manufacturers and the International Organization for Standardization (ISO) to establish an international standard. This standard is known as ISO 24711 Testing Guidelines and is comprised of five letter-sized pages that each manufacturer uses to test printers until they run out of ink. Since all manufacturers agreed to the standard set of pages, it should be easy to compare the results.
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.
- Mixed text and graphics document (ISO/IEC FCD 24712)
- Color photo set (10x15cm)
- Color photo (A3+)*
