ISO/IEC 24735 Method for Measuring Digital Copying Productivity

ISO/IEC 24735 specifies a method for measuring the productivity of digital copying devices using varying characteristics on plain paper in default mode. It is applicable to black-and-white and color devices, regardless of print technology. (e.g. inkjet, laser, etc)

ISO/IEC 24735 is only applicable to devices that include an automatic document feeder and the ability to collate a 4 page job. However, the standard includes Annex D which provides information and guidance on how to test a device without an ADF or collation. See ISO/IEC 24735 Annex D page for more information

1. Short Jobs
   • 1 set
2. Medium Jobs
   • 1 set plus about 30 seconds of additional copying
3. Long Jobs
   • 1 set plus about 4 minutes of additional copying

1. Time from the initiation of the copy job until the last page (4th page) of the first set lands in the output tray
   • The time resulting from this measurement is referred to as First Set Out Time (FSOT).
      
2. Time from the initiation of the copy job until the last page of the job lands in the output tray
   • A PPM resulting from this measurement is referred to as Effective Throughput (EFTP).
      
3. Time from when the last page in the first set (4th page) lands in the output tray until the last page of the job lands in the output tray.
   • A PPM resulting from this measurement is referred to as Estimated Saturated Throughput (ESAT).

• FSOT for the short job.
• EFTP for the short, medium and long jobs.
• ESAT for the medium job. HP generally advertises the average single-sided ESAT PPM.

ISO is a network of the national standards institutes of 157 countries, one member per country, with a Central Secretariat in Geneva, Switzerland, that coordinates the system.

ISO is a non-governmental organization that forms a bridge between the public and private sectors. Many of its member institutes are part of the governmental structure of their countries, or are mandated by their government. Other members have their roots uniquely in the private sector, having been set up by national partnerships of industry associations.

Therefore, ISO enables a consensus to be reached on solutions that meet both the requirements of business and the broader needs of society. For more information on ISO see www.iso.org .
