Consumable Yield Testing and Reporting

Overview

Customers are becoming increasingly aware of the cost of owning and operating their

printers and multifunction products (MFPs). The cost of consumable supplies such as

toner cartridges or solid ink sticks is a major component of the Total Cost of Ownership

(TCO) for a printer or MFP. The per-page cost of printing is driving many printer and

MFP purchase decisions today, as these costs can be combined with print volume and

print coverage assumptions to give companies a reasonable estimate of the monthly

and annual TCO for a speciﬁc printer or MFP.

In the past, printer and MFP original equipment manufacturers (OEMs) used different,

proprietary methods for testing and reporting consumable yields. This made factual

and accurate comparisons of products from differing OEMs impossible. Reporting was

traditionally done using “5% area coverage,” but that did not guarantee comparable

results because many other testing variables affect the stated yield, including:

Page size and margin settings

Image types used to create 5% area coverage

Number of cartridges used during testing process

Number of printers/MFPs used during testing process

Environmental testing conditions (humidity, temperature, and so on)

Lack of stated conﬁdence level for published consumable yield

Any variation in these factors during the testing process can cause nontrivial differences

in reported yields. The development of an industry standard methodology for testing

and reporting consumables yields has helped alleviate these inconsistencies, and gives

customers the reliable information they need to make their technology decisions.
