ISO/IEC 29183:2021(E)
Introduction
Many digital copying devices produce copied pages at a different rate than their nominal speed when
running with different quality modes, different substrate grammage, different job content and job
lengths. The degree to which a change in productivity is experienced depends significantly on other
parameters of the job stream. The most dominant of the parameters of the job stream are: (image
quality modes selected, job content, B&W and colour reproduction job stream, run length). The existing
International Standard (ISO/IEC 24735) only addresses the productivity issues for digital copying
devices when using both collation and an ADF (automatic document feeder) and cannot be used for a
single one sided original.
This document provides a general method for measuring productivity when the above-mentioned job
stream parameters for digital copying devices are taken into consideration. This document also includes
instructions for the creation of test charts. It allows manufacturers and buyers of digital copying
devices to describe the productivity of various digital copying devices with respect to representative
office usage.

ISO/IEC 29183:2021(E)
4.4 Paper
The output paper used in this test shall be within the range of, and/or not violate, specific written
attribute guidelines and recommendations provided by the copying device manufacturer, which may
include but are not limited to: size, grammage, composition, paper manufacturer(s), paper type, part
number and other physical characteristics. Care shall be taken to use a paper that conforms to the
copying device manufacturers' paper specifications for the default copying device settings. The paper
used for the performance test 5.4 shall be cut sheet, A4 and/or 8,5" × 11" (215,9 mm × 279,4 mm) size.
The paper used in the test shall be recorded in the full detailed test report.
The same paper size should be used for each machine when wanting to compare the productivity
results of one machine with other machines. If the copying device is used in “thick paper mode” for
copying, then this optional mode should be noted on the full detailed report format in corresponding
column in Annex B.
4.5 Maintenance
Copying device maintenance routines shall be performed throughout testing per the manufacturer's
recommendations on an as needed basis.
EXAMPLE Examples of maintenance routines:
— cleaning routines;
— consumables replacement.
4.6 Preparation of test targets (test charts)
The copying test file is outlined in Annex C.
This test file is from ISO/IEC 24735. The test file consists of four single-sided pages. When using the
test file for the copying productivity test, the test targets shall be created by printing the most recent
electronic test file. If the intended machine does not have a printer function, then record the name of
the printer which is used to print out the actual test targets.
The quality of test targets may affect the productivity measurement. Test targets should be created
according to the following instructions.
a) The test targets shall be printed by the equipment to be tested in its default-printing mode in
simplex mode.
b) The paper used for creating the test targets shall have a brightness of at least 80 % to eliminate the
influence of background.
2
c) The paper used for creating the test targets shall be 64 g/m or above and sufficiently opaque.
d) The paper used for creating the test targets shall be free of wrinkles or other surface defects.
e) Confirm that there are no defects such as unexpected dots or contamination on the paper.
f) Page scaling shall not be used. Typically, this is done by setting page scaling to “none”. Options such
as “Fit to printable area” shall not be used.
The brightness shall be measured according to ISO 2470-1. The paper grammage shall be measured
according to ISO 536.

ISO/IEC 29183:2021(E)
4.7 Environment
The test environment, including temperature and humidity, shall be within the ranges recommended
by the manufacturer for operating the device. If no recommendation is available, the following ranges
shall apply:
— temperature: 18 °C to 25 °C,
— relative humidity: 30 % to 70 %.
The temperature and humidity ranges of the test environment shall be recorded in the full detailed report.
4.8 Voltage
The copying device shall be connected to a voltage supply within the manufacturer specified operating
voltage range for the copying device under test. The voltage should be measured under no-load
condition prior to each test suite and recorded in the full detailed report.
NOTE It is possible that devices that utilise a heater have a longer sFCOT time when the line voltage is at the
lower value of the recommended operating range.
5 Test method
5.1 Overview
The test procedures in this document apply to tests using either the scanning glass or ADF. For devices
with both ADF and a scanning glass testing with the scanning glass is mandatory, testing with the ADF
is optional. If the test is performed with the scanning glass and the ADF, then results from both tests
shall be documented in the full test report. It is acceptable to test with only the ADF if it is the only
scanner input path. This may be the case on scroll fed scanners, such as those typically found on fax
machines.
A single copy (1 copy test) of the relevant test target is copied in order to measure first copy out time
from ready (sFCOT ), sleep (sFCOT ), and off (sFCOT ). Multiple, N sets, of each relevant test
ready sleep off
target are copied and measured for the 1 copy + 30 seconds test run to calculate estimated saturated
throughput (sESAT ) and effective throughput (sEFTP ), where N is the number of sets needed to
30sec 30sec
meet sLSOT - sFSOT ≥ 30 s , and sLSOT is the last set out time for the 1 copy + 30 seconds
30sec 30sec 30sec
test. The 1 copy + 4 minutes test is a similar concept used to calculate sEFTP .

4.4 Paper
The output paper used in this test shall be within the range of, and/or not violate, specific written
attribute guidelines and recommendations provided by the copying device manufacturer, which may
include but are not limited to: size, grammage, composition, paper manufacturer(s), paper type, part
number and other physical characteristics. Care shall be taken to use a paper that conforms to the
copying device manufacturers' paper specifications for the default copying device settings. The paper
used for the performance test 5.4 shall be cut sheet, A4 and/or 8,5" x 11" (215,9 mm x 279,4 mm) size.
The paper used in the test shall be recorded in the full detailed test report.
The same paper size should be used for each machine when wanting to compare the productivity
results of one machine with other machines. If the copying device is used in “thick paper mode” for
copying, then this optional mode should be noted on the full detailed report format in corresponding
column in Annex B.
4.5 Maintenance
Copying device maintenance routines shall be performed throughout testing per the manufacturer's
recommendations on an as needed basis.
EXAMPLE Examples of maintenance routines:
— cleaning routines;
— consumables replacement.
4.6 Preparation of test targets (test charts)
The copying test file is outlined in Annex C.
This test file is from ISO/IEC 24735. The test file consists of four single-sided pages. When using the
test file for the copying productivity test, the test targets shall be created by printing the most recent
electronic test file. If the intended machine does not have a printer function, then record the name of
the printer which is used to print out the actual test targets.
The quality of test targets may affect the productivity measurement. Test targets should be created
according to the following instructions.
a) The test targets shall be printed by the equipment to be tested in its default-printing mode in
simplex mode.
b) The paper used for creating the test targets shall have a brightness of at least 80 % to eliminate the
influence of background.
2
c) The paper used for creating the test targets shall be 64 g/m or above and sufficiently opaque.
d) The paper used for creating the test targets shall be free of wrinkles or other surface defects.
e) Confirm that there are no defects such as unexpected dots or contamination on the paper.
f) Page scaling shall not be used. Typically, this is done by setting page scaling to “none”. Options such
as “Fit to printable area” shall not be used.
The brightness shall be measured according to ISO 2470-1. The paper grammage shall be measured
according to ISO 536.

4.7 Environment
The test environment, including temperature and humidity, shall be within the ranges recommended
by the manufacturer for operating the device. If no recommendation is available, the following ranges
shall apply:
— temperature: 18 °C to 25 °C,
— relative humidity: 30 % to 70 %.
The temperature and humidity ranges of the test environment shall be recorded in the full detailed report.
4.8 Voltage
The copying device shall be connected to a voltage supply within the manufacturer specified operating
voltage range for the copying device under test. The voltage should be measured under no-load
condition prior to each test suite and recorded in the full detailed report.
NOTE It is possible that devices that utilise a heater have a longer sFCOT time when the line voltage is at the
lower value of the recommended operating range.
5 Test method
5.1 Overview
The test procedures in this document apply to tests using either the scanning glass or ADF. For devices
with both ADF and a scanning glass testing with the scanning glass is mandatory, testing with the ADF
is optional. If the test is performed with the scanning glass and the ADF, then results from both tests
shall be documented in the full test report. It is acceptable to test with only the ADF if it is the only
scanner input path. This may be the case on scroll fed scanners, such as those typically found on fax
machines.
A single copy (1 copy test) of the relevant test target is copied in order to measure first copy out time
from ready (sFCOT ), sleep (sFCOT ), and off (sFCOT ). Multiple, N sets, of each relevant test
ready sleep off
target are copied and measured for the 1 copy + 30 seconds test run to calculate estimated saturated
throughput (sESAT ) and effective throughput (sEFTP ), where N is the number of sets needed to
30sec 30sec
meet sLSOT - sFSOT ≥ 30 s , and sLSOT is the lasst set out time for the 1 copy + 30 seconds
30sec 30sec 3
