Canon, Epson, HP, and Lexmark, support new ISO

EpsonCanon, Epson, HP, and Lexmark, announced their support of the new International Organization for Standardization (ISO) standard, ISO/IEC 19752, for monochrome toner cartridge yield in monochrome laser printers. Canon, Epson, HP, and Lexmark are leading proponents of industry standards and believe a single, rigorous, worldwide ISO standard to measure monochrome toner cartridge yield will help customers more objectively and accurately evaluate printer and print cartridge yield. The new ISO standard for monochrome toner cartridge yield clearly defines the key attributes that affect yield and applies robust statistical analysis so all manufacturers can utilize the same methodology when measuring yield.
For instance, instead of testing a couple of cartridges on a single printer, this standard requires that at least nine cartridges be tested on a minimum of three separate printers. Rather than taking the average of the yield of the nine cartridges, a robust statistical method is used to calculate the lower 95 percent confidence bound. This more accurately represents the potential customer experience by taking into account manufacturing variations in the performance of the cartridges and the printers. Until now, printer manufacturers have used a variety of methodologies to measure toner yield, making it challenging for customers to accurately compare yield measurements from leading suppliers.

Canon, Epson, HP, and Lexmark have supported and acted as key participants in ISO's development of an industry standard for determining toner cartridge yield for monochrome laser printers. These companies believe the standard's robust criteria and consistency, ISO's unbiased and global approach, and the industry-wide participation in developing the standard will result in significant benefits for customers and the printing industry alike. The new standard can be used to evaluate OEM (original equipment manufacturer), remanufactured and refilled toner cartridges.

"ISO's voluntary standards must be robust to endure the rigorous processes that ensure they meet the requirements of businesses and their customers worldwide and the designation of 'ISO International Standard'," said Roger Frost, ISO Press and Communications Manager. "Developed by experts from organizations throughout the world in the sectors that will put them to use, the standards represent an international consensus on state-of-the-art solutions for technological and business challenges."

"The new ISO standard for determining monochrome toner yield puts a solid foundation in place to evolve standards for colour laser and inkjet technology," said Mogens Molgaard Jensen, Executive Vice President of Canon Europe and Head of Consumer Imaging for Canon Europe, Middle East and Africa.

"This new standard should be a call to action for the printing industry to support and adhere to these new, rigorous testing methodologies to measure monochrome toner cartridge yield, and also seek to formulate similar standards for color cartridges," said Seiichi Hirano, director and chief executive of the Imaging and Information Products Operations Division, Seiko Epson Corp. "Widespread adoption will ensure customers have access to yield information they can rely on when making the purchase decision."

"Customers can be assured that companies who support and adhere to the new ISO standard are using the most robust testing criteria available for determining monochrome toner printer yield," said Pradeep Jotwani, senior vice president, HP Imaging and Printing Group, supplies. "However, yield is only one among many factors in the overall costs of printing. To get the best overall value, we advise our customers to consider reliability, productivity, quality, speed, and ease of use as well."

"Lexmark actively supported the development of the ISO standard for monochrome toner print cartridge yield (for monochrome laser printers)," said Paul Rooke, Lexmark executive vice president and president of its Printing Solutions and Services Division. "We believe ISO's unbiased, global approach will result in significant customer and industry benefits."

ISO is an internationally recognized organization that has successfully developed many important and broadly used standards by working closely with standards organizations around the world and from all parts of the printing industry to arrive at unbiased, robust, reliable standards on behalf of customers.

Following are key provisions of the ISO standard for monochrome toner cartridge yield:

Technically Robust Testing Criteria
• Standard test document: Use of a standard page printed in a controlled environment with printer default settings.
• Number of cartridges tested: A minimum of nine of each cartridge is tested until they stop printing, allowing reliable estimates of lowest predicted yield with statistical confidence.
• Source for cartridges: Cartridges and printers used represent those available to customers on the open market.
• Clear, objective, end-of-life criteria: Determines cartridge yield through measurements that establish an end-of-life criterion
• Number of printers: A minimum of three cartridges are tested on three different printers to avoid bias due to printer variability.
• Controlled environment: Printing environment is controlled and consistent because temperature and humidity variations affect yield.
• Objectivity: Because of worldwide and industry-wide participation, the testing criteria reflect objectivity in developing a reliable and rigorous standard.

Consensus-Driven International Standards
Canon, Epson, HP, and Lexmark, along with other OEMs, are also working with the ISO cartridge standards committee to develop a similar standard for color inkjet cartridges and printers as well as color laser cartridges and printers. These standards are expected to be complete in 2005.
