How Expected Print Yield Page is CalculatedJune 7, 2010 No Comments
All ink and toner cartridge stores include the print yield page of a cartridge when it is packed for the customers to know whether it is worth it or not. Some say that their product can yield up to 4,000 pages while others stick to an estimate of 2,000 sheets. So if the cartridge type is the same but the expected printouts differ, how does a cartridge manufacturer determine its products’ probable print yield page?
1. Standard Test Document
When a printing test is made, the standard size of a document is used to maintain consistency in the testing while also keeping the default settings of a printer. The usual sizes for this test are letter size or A4 size.
2. Number of Tested Cartridges
To make sure that the counting of yielded page is consistent, a manufacturer uses a minimum of nine cartridges on the testing stage. Some may even consume more than that number, nevertheless, the level of statistical confidence will usually be measured at 95%.
3. The Life of a Cartridge
The life span of a printer cartridge is a very important factor in determining the amount of pages that it can create. It is advisable to always follow the instructions in using a cartridge to keep its life period as indicated by the manufacturer.
The testing of the cartridges is also done on different types of printer to keep the compatibility of a printer and a cartridge. Most of the time, these are the ways done by makers of printer cartridges to determine the estimated print yield page, although in some instances, other processes are also done for validation.
