Ink Yields

ISO Ink Cartridge Page Yields

In accordance with the ISO standard for individual colour cartridges, colour yields are determined by taking an average yield, based on continuous printing, of all individual colour cartridges. Individual cartridges conveniently allow the user to replace just the colour of ink that has been expended. When using cartridges with combined colour tanks, as do some competitive products, several colours of ink must be replaced when one colour has been expended, so ISO ratings are based on the first colour to be expended.

Replacement cartridge yields are based on ISO tests in default mode printing continuously. Cartridge yields vary considerably for reasons including images printed, print settings, temperature and humidity. Yields may be lower when printing infrequently or predominantly with one ink colour. All ink colours are used for printing and printer/all-in-one maintenance, and all colours have to be installed for printing. For print quality, part of the ink from the included cartridges is used for printer startup and a variable amount of ink remains in the cartridges after the "replace cartridge" signal. Epson recommends that customers choose an ink jet printer based on their expected printing needs, considering cartridge yields as just one factor of evaluation. Other important factors include image quality, fade resistance of prints, reliability and printer features.

ISO Ink Cartridge Page Yields — Testing Methodology

Epson provides ink cartridge page yields (the "page yield" means the number of document pages) based on the ISO/IEC 24711 and 24712 standards for ink jet products, which excludes the first installed cartridges. The following is a brief summary of Epson's ink cartridge page yield testing, conducted in accordance with the ISO/IEC 24711 and 24712 standards.

A suite of five patterns (shown below) is printed continuously, in consecutive order, on at least three printers. Cartridges are replaced when the printer indicates cartridges are expended and will not print without replacing the cartridge.
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.
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.

Ink Page Yields for Ink Packs

In accordance with Epson’s methodology for individual ink packs, colour yields are determined by taking an average yield, based on continuous printing, of all individual ink packs. Individual ink packs conveniently allow the user to replace just the colour of ink that has been expended.

Replacement ink pack yields are based on Epson tests in default mode printing continuously. Ink pack yields vary considerably for reasons including images printed, print settings, temperature and humidity. Yields may be lower when printing infrequently or predominantly with one ink colour. All ink colours are used for printing and printer/all-in-one maintenance, and all colours have to be installed for printing. For print quality, part of the ink from the included ink packs is used for printer startup and a variable amount of ink remains in the ink packs after the "replace ink pack" signal. Epson recommends that customers choose an ink jet printer based on their expected printing needs, considering ink pack yields as just one factor of evaluation. Other important factors include image quality, fade resistance of prints, reliability and printer features.

Epson Ink Pack Page Yields — Testing Methodology

Epson 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. 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. The following is a brief summary of Epson's ink pack page yield testing, conducted in accordance with Epson’s stringent testing standards.

A suite of five patterns (shown below) is printed continuously, in consecutive order, on at least three printers. 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.
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.
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.

Ink Page Yields for Ink Bottles

In accordance with Epson’s methodology for individual ink bottles, colour yields are determined by taking an average yield, based on continuous printing, of all individual ink bottles. Individual ink bottles conveniently allow the user to refill just the colour of ink that has been expended.

Replacement ink bottle yields are based on Epson tests in default mode printing continuously. Ink bottle yields vary considerably for reasons including images printed, print settings, temperature and humidity. Yields may be lower when printing infrequently or predominantly with one ink colour. All ink colours are used for printing and printer/all-in-one maintenance, and all colours have to be installed for printing. For print quality, part of the ink from the included ink bottles is used for printer startup and a variable amount of ink remains in the ink tanks after the "refill tank" signal. Epson recommends that customers choose an ink jet printer based on their expected printing needs, considering ink bottle yields as just one factor of evaluation. Other important factors include image quality, fade resistance of prints, reliability and printer features.

Epson Ink Bottle Yields — Testing Methodology

Epson 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. Epson must test ink bottle yields with ISO/IEC 24712 patterns. Epson has developed an internal methodology that adapts the ISO methodology to a CISS printer and adapts the ISO/IEC 24711 methodology because initial ink cannot be extracted from the ink tank. The following is a brief summary of Epson's ink bottle yield testing, conducted in accordance with Epson’s stringent testing standards.

A suite of five patterns (shown below) is printed continuously, in consecutive order, on at least three printers. Ink tanks are refilled when the printer indicates ink is expended and will not print without refilling the ink tank.
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.
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.

Print patterns used during page yield testing for colour inkjet printers

Page yields for monochrome inkjet printers are based on the ISO/IEC 24711 standard using the ISO/IEC 19752 pattern.

ISO Ink Cartridge Photo Yields

Epson provides ink cartridge photo yields (the "photo yield" means the number of 4" x 6" photo prints) based on the ISO/IEC 29102 and 29103 standards for ink jet products. The following is a brief summary of Epson's ink cartridge photo yield testing, conducted in accordance with the ISO/IEC 29102 and 29103 standards.

A suite of six patterns (shown below) is printed continuously, in consecutive order, on at least three printers. Cartridges are replaced when the printer indicates cartridges are expended and will not print without replacing the cartridge.
Testing is conducted at a controlled temperature in default Photo Mode on 4"x6" photo paper without border (if both border and borderless printing allowed) and with a border (if only border printing is allowed) with print commands from a late model PC with a Microsoft Windows operating system.
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.
