BS ISO/IEC 17991:2015 pdf download-Information technology — Office equipment — Method for Measuring Scanning Productivity of Digital Multifunctional Devices.
4.4 Maintenance Scanning device maintenance shall be performed throughout testing per the manufacturer’s recommendations. 4.5 Preparation of Test Targets (Test Charts) The scanning test file is outlined in Annex C. This test file is from ISO/IEC 24735 “Method of measuring digital copying productivity”. The test file consists of 4 single sided pages. When using the test file for the scanning productivity test, the test targets shall be created by printing the most recent electronic test file on the device to be tested if it has print capability. If the test device to be tested does not have a printer function or if the device is a colour capable scanner but does not have a printing function of colour test targets (for the colour scanning test), then record the name of printer which is used to print out the actual test targets. The most recent official electronic file (ISO_IEC_24735_2009_Test_Pages.pdf) can be located at http://standards.iso. org/ittf/PubliclyAvailableStandards/SC28_Test_Pages/ . As for preparation method for double-sided targets, refer to Annex C. The quality of test targets may affect the productivity measurement. Test targets should be created according to the following: a) The test targets shall be printed by the equipment to be tested itself in its default-printing mode. (If the test device to be tested does not have a printer function or if the device is a colour capable scanner but does not have a printing function of colour test targets (for the colour scanning test), then record the name of printer which is used to print out the actual test targets.) b) The paper used for creating the test targets shall have a brightness of at least 80 % to eliminate the influence of background. c) The paper used for creating the test targets shall be 64 g/m 2 or above and sufficiently opaque to prevent scanning of images on the backside. d) The paper used for creating the test targets shall be free of wrinkles or other surface defects.
