In recognition of various factors that can affect yields, declared yields are rounded down (not up) in amounts that are at least sufficient to assure accuracy and reliability.Įpson provides ink bottle yields (the "page yield" means the number of document pages) based on the ISO/IEC 24712 test patterns with Epson’s methodology for ink jet products, which includes the initial ink.Ink packs (including the initial ink packs) are replaced when the printer indicates ink packs are expended and will not print without replacing the ink pack. A suite of five patterns (shown below) is printed continuously, in consecutive order, on at least three printers.The following is a brief summary of Epson's ink pack page yield testing, conducted in accordance with Epson’s stringent testing standards. Epson must test ink pack yields with ISO/IEC 24712 patterns and adapt the ISO/IEC 24711 methodology as the ink capacities of the initial ink packs far exceed the capacities of ink cartridges. In recognition of various factors that can affect yields, declared yields are rounded down (not up) in amounts that are at least sufficient to fulfill the standard deviation formula built into the ISO standard to assure accuracy and reliability.Įpson provides ink pack page yields (the "page yield" means the number of document pages) which are estimated based on the ISO/IEC 24711 test in Default Mode for ink jet products, which includes the initial ink packs.Testing is conducted at a controlled temperature in Default Mode on plain paper with print commands from a late model PC with a Microsoft Windows operating system.
Cartridges are replaced when the printer indicates cartridges are expended and will not print without replacing the cartridge.
The following is a brief summary of Epson's ink cartridge page yield testing, conducted in accordance with the ISO/IEC 2472 standards. Epson provides ink cartridge page yields (the "page yield" means the number of document pages) based on the ISO/IEC 2472 standards for ink jet products, which excludes the first installed cartridges.
