BS ISO-IEC 29102-2015 pdf free download – Information technology — Office equipment — Method for the determination of ink cartridge photo yield for colour printing with inkjet printers and multi-function devices that contain inkjet printer components.
The purpose of this International Standard is to provide a method to determine the ink cartridge photoyield of ink-containing cartridges (i.e. integrated ink cartridges and ink cartridges without integratedprintheads) for colour photo printing with colour inkjet printers and multifunction devices that containinkjet printer components. In the case where a cartridge set can be used in multiple printer models,only one yield test needs to be performed as long as the difference between printer models does notimpact yield.
NOTE A cartridge supplier may choose to use more than one market identifier for a single physical cartridge.ln this case only one yield test is required as long as there are no differences in the cartridges other than marketidentifiers.
This International Standard prescribes the following:
– the test method that manufacturers, test laboratories, etc.use to determine ink cartridge photo
yield;
– the method for determination of declared photo yield values from the test results; and
the appropriate method of describing the photo yield of cartridges in documentation supplied to theconsumer by the manufacturer.
This International Standard is only intended for the determination of ink cartridge photo yield.Noother claims can be made from this testing regarding quality, reliability, etc.
This International Standard can be used to determine the yield of any cartridge that is used during theprinting of the photo test file defined in ISO/IEC 29103.
This International Standard is not for use with printers whose minimum printable size is equal to orgreater than A3.This International Standard is not intended to measure the yield of photo printing onpaper size larger than 4×6, L or A6.In addition, this International Standard is not for use with industrialprinters or point of sale printers.It only applies to desktop printing systems.

3Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
fade
phenomenon in which a significant colour change occurs due to ink depletion
Note 1 to entry: If a printer exhibits fade, a five minute pause is allowed to provide for recovery of the ink deliverysystem and printing can continue. lf fade appears on the next page, then the cartridge is judged at end of life andthe additional page printed after the five minute pause is not counted in the yield calculation. If fade does notappear on the next page, then printing can continue until the next fade or ink out is encountered.
Note 2 to entry: For examples of fade, please consult Annex A.
Note 3 to entry: In some printer systems, fade can occur prematurely due to the way that ink is provided to theprinting system.
Note 4 to entry: It can be helpful to use the first photo test suite print samples from the first cartridge set forcolour comparison.
Note 5 to entry: A blue light source (such as a blue LED) can be used to help in the detection of yellow fade.
3.2
streak
thin lines of colour that appear in test imagesNote 1 to entry: Streaks differ from fade in the width.
Note 2 to entry:lf streaks occurin two or more out of four consecutive test pages,then a streakremoval operationis required.
Note 3 to entry: Streaks can appear due to a number of reasons; thermal issues and clogged nozzles being two ofthe main causes.Comparisons are made using the phenomenon sample provided in Annex B.
3.3
streak removal operation
procedure used to restore the print performance by removing streaksNote 1 to entry: lt is often called a nozzle cleaning operation.
Note 2 to entry: If streaks are observed in two or more out of four consecutive test pages, first the printer canbe left idle for five minutes. Then an additional four pages are printed. If the streaks are still observed, then astreak removal operation is conducted according to the latest printer manufacturer documentation. Due to thesignificant amount of ink that is used for cleaning, the maximum permissible number of times that the streakremoval operation can be used on a given cartridge is prescribed in 5.2.1. All test pages printed during thisprocess will be included in the page count for determining the yield.BS ISO-IEC 29102 pdf download.
