How Epson Measures Inkjet Print Speeds

In 2009, the inkjet printer industry adopted a new international standard for measuring print speeds. This standard, known as ISO/IEC 24734, is the most reliable method to test print speeds of inkjet printers, all-in-one printers and lasers under standard conditions.

ISO Print Speeds

ISO/IEC 24734 International Standard

ISO print speeds, also known as ISO/IEC 24734 print speeds, give an "apples-to-apples" speed comparison across various models for all printer manufacturers using the same method of measurement. This allows consumers to gauge the true performance of printers, in order to accurately identify a product that will match their needs.

Detailed Print Speed Reports

Methodology

Laser quality black and color print speeds are determined in default, single-side mode in accordance with ISO/IEC 24734. Actual print times will vary based on system configurations, software version, and page complexity.

Test Patterns Used

A set of four pages are printed in various formats (Word®, Excel®, & Adobe® Reader).

Terms and Measurements

Office Category Test - Set of typical office documents used to measure print speeds.
FSOT (First Set Out Time) - Time to complete printing of the entire document set in seconds.
EFTP (Effective Throughput) - Average print speed for all document sets. This measurement is expressed in images per minute (IPM) or pages per minute (PPM).
ESAT (Estimated Saturated Throughput) - Average print speed for all document sets excluding the first set. This measurement is expressed in images per minute (IPM) or pages per minute (PPM).
1 set test - Average print speed for one set of typical office documents.
1 set + 30 seconds test - Average print speeds for multiple set of documents (one set of typical documents plus 30 seconds).
1 set + 4 minutes test - Average print speed for multiple set of documents (one set of typical documents plus 4 minutes).
Duplex and Simplex - Simplex refers to single-sided printing. Duplex refers to automatic, two-sided printing. Epson reports duplex speed for models with automatic, two-sided printing.

 

Maximum Print/Copy Speeds

Methodology

Maximum pages/copies per minute (PPM/CPM) are measured after first page with text patterns in Draft Mode (or Economy Mode, depending on the printer/all-in-one) on plain paper. Actual print/copy times will vary based on system configuration, software, and page complexity.

Testing is conducted with the patterns depicted below in Microsoft® Word. The printer/all-in-one uses plain, 8.5" x 11" paper. Tests are performed at least three times using at least three sample products. Tests do not measure processing time, which varies, depending on the computer configuration, image, software, and connectivity. Timing begins when the second page starts to feed into the product and continues for 60 seconds. Results are rounded down, but not rounded up.

Color Photo Print Speeds

Color photo printed without borders in Draft Mode on Premium Photo Paper Glossy measured from start of paper feed. Actual print times will vary based on system configuration, software, and page complexity.

Testing is conducted with the image depicted below using Adobe® Photoshop® software on photo paper in draft mode, unless otherwise specified. Tests are performed at least three times using at least three sample products. Tests do not measure processing time, which varies, depending on the computer configuration, image, software, and connectivity. Timing begins from commencement of paper feed until the photo ejects. Results are rounded down, but not rounded up.

Testing Conditions and Equipment Used

Tests are run in a climate-controlled office environment (72 ºF, about 40% relative humidity), using current, readily available equipment. As of May 2008, Epson began using Dell® Dimension series desktop computers with Intel® Core 2 Duo 1.86 GHz or Athlon 64 X2 Dual Core 2.20 GHz processors with 2.0GB of RAM running Microsoft Windows XP, Service Pack 3. Imaging devices are connected via USB 2.0 cables. Time is recorded by a lab technician with an electronic stopwatch.
