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.

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.
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 2021 – All rights reserved 5
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 .
4min
The 1 copy + 30 seconds test is used to provide a test for products across varying segments. Without
defining and categorizing products by segments, this simple method allows faster products to be
tested with more sets and slower products to be tested with fewer sets, therefore more consistent
with their usage.
The 1 copy + 4 minutes test is intended to provide a test to illustrate that differences in productivity
can occur for longer printing times compared to shorter printing times. It is understood and recognized
that 4 min may be a long test for some devices, but a short test for other, higher end devices. The 4 min
time is a compromise to meet the needs of the many products across many segments covered in the
scope of this document.
In order to ensure clarity between the results of each test and to avoid test result confusion that can be
caused by back to back job spooling effect, each copy job test should be started only after the last copy of
the previous test has been fully ejected from the machine and the device has returned to a ready state.
Repeat the (1 copy test, 1 copy + 30 seconds test, and 1 copy + 4 minutes test) for each required/
optional test target, test suite, as applicable for the relevant copying modes on the device under test.
(See Table 2, and/or Table 3.)
6 © ISO/IEC 2021 – All rights reserved
5.2 Test measurement procedure
5.2.1 Test setup
Before testing, the following setup activities shall be completed.
a) Install the copying device following the manufacturer's recommendations.
b) Clean the surface of the image scanning device if needed.
c) The default required tests shall be run after the copying device has warmed-up and entered a ready
state. Use of warm-up copying (that means at least one page is copied just before testing) to ready
the copying device is acceptable.
d) Set the system parameters (such as paper grammage selection, paper size and feed orientation,
quality mode) for test. Record the copying device model, configuration (options), default condition
and any other variations if selected. If the system has automatic media detect (automatic paper
type selection), it can be disabled, and paper used in the test shall be selected manually. This shall
be noted in the full detailed report.
e) Refer to Annex B for an example of settings to record. Refer to 5.4 for information on required tests.
Refer to Clause 6 for information on the calculation and treatment of data. Refer to Clause 7 for
information on data reporting.
f) Prepare the test targets (test charts) that will be used in the test, identified as described in 4.6, and
place the target on the scanning glass of the device.
g) Refer to 5.4 to decide what tests are to be run.
h) The 1 copy test and the 1 copy + 30 seconds test are required for each test target A, B, C, and D. Only
test target A is required for the 1 copy + 4 minutes test while test targets B, C, and D are optional.
These tests can be performed in any order with any of the test targets.
NOTE 1 Four test targets are used in order to test the productivity versus the content of various originals.
This document is not designed or intended to test the time it takes for an operator to switch originals on the
scanner glass.
i) As described in 5.3.4, if the saturated time per copy is consistent to ±5 % between the four test
targets, testing can be carried out on only test target A. If only test target A is used, it shall be noted
in the full detailed test report.
j) Determine the ready delay time between jobs. The (sFCOT, 1 copy test, 1 copy + 30 seconds test, and
1 copy + 4 minutes test) from ready for some devices is sensitive to the ready delay time from the
exit of the last page of the previous copy job to the initiation of the next job. The ready delay time
used shall be no shorter than 20 s and no longer than 50 s; however, care shall be taken to select a
ready delay time that places the device in a stable condition. If the tester is unsure of what ready
delay time will place the device in a stable condition, the procedure in Annex D shall be used to
establish a ready delay time to place the device in a stable condition. The ready delay time used
may be different from what Annex D would indicate as long as the (sFCOT, 1 copy test, 1 copy +
30 seconds test, and 1 copy + 4 minutes test) result is equivalent to the (sFCOT, 1 copy test, 1 copy
+ 30 seconds test, and 1 copy + 4 minutes test) at the ready delay time that Annex D would have
selected. The ready delay time and whether a ready delay time found with Annex D was used shall
be noted in the full report.
NOTE 2 In general, electro-photographic devices are in a stable condition at 50 s , although many devices
can be in a stable condition in less than 50 s . With inkjet devices, an unstable condition happens during a
print head capping or servicing routine.
k) Determine the default power management delay time to the lowest power sleep state.
This may be done through examining device settings, timing how long until a device user interface
(UI) switches from ready to the lowest power sleep state, or by consulting device documentation
© ISO/IEC 2021 – All rights reserved 7
or the device manufacturer. If no information can be found on the default power management delay
time to the lowest power sleep state, a delay of 60 min shall be used.
An additional wait is added after the power management delay time to sleep determined above.
The additional wait is 60 min. If the device under test is an inkjet device, and the recovery time is
known to be independent from the length of time elapsed after entering sleep, instead of waiting
an additional 60 min, an additional wait of 10 min is allowed. If 60 min is not used as the additional
wait time, the additional wait time and reason 60 min was not used shall be noted in the full report.
The total delay time is the sum of the power management delay time and the additional delay time.
The total delay time from the complete exit of the last page of the previous job to the initiation of
the next job shall be noted in the full detailed report.
If the device enters off state automatically during the sFCOT from sleep test, the device shall be
turned on manually, and noted as such in the full report. The result of the test shall still be reported
as sFCOT from sleep.
An optional test is to measure sFCOT from sleep with a total delay time from complete exit of the
last page of the previous job to the initiation of the next job after a 15 min total delay time.
l) Default delay time for sFCOT from off is 60 min.
5.2.2 “1 copy” test from ready
The procedure to measure sFCOT and sEFTP is defined by the following steps.
ready 1copy
a) Enter copy set count = 1 and press the copy start button. Start the ready delay timer when the page
has fully exited from the device.
NOTE 1 Step a) is skipped when the ready delay timer is started at the end of a different test.
b) Enter copy count = 1 required for this specific test run on the copying device operation panel.
c) [Start test run] At the end of the ready delay time, press the copy start button and simultaneously
start the timing device (watch or otherwise).
d) Record the time for completion of one copy to at least two decimal places and start the ready
delay timer.
e) [End test run]
f) Run the 1 copy test steps b) – e) twice. Determine if the results are consistent within ±5 % according
to 5.3.2, and perform a third test run if required. (The data from the test is average of the individual
runs. Three iterations are the maximum and the results from all iterations are averaged to get the
required data.)
g) Calculate the average sFCOT and sEFTP for the current test target according to Clause 6.
ready 1copy
NOTE 2 If sFCOT is constant regardless of copy count, a copy count of 2 can be used, and this test used as
the initial test described in 5.3.2.
5.2.3 “1 copy” test from sleep
The procedure to measure sFCOT is defined by the following steps:
sleep
a) Preconfigure the device settings to be the same as the current test run.
NOTE 1 The intent is to enable pressing just the start button to begin the copy job.
b) Make a copy job at the device using page A of the test targets and the same copy mode settings as
the current test run.
8 © ISO/IEC 2021 – All rights reserved
c) When the page has fully exited from the device, start a timing device for the total delay time.
d) Wait until the total delay time has elapsed before continuing.
e) Use one of the following two methods to perform copy job.
1) If the device is in sleep state: when the total delay time has elapsed, select the copy start button
and simultaneously start the timing device (watch or otherwise). The time measurement is
started when the copy start button is first pressed. In the case that the measured results are
the same, quick copy, or similar features may be used to initiate the copy job.
NOTE 2 It is possible that the copy start button needs to be pressed multiple times to wake the
device and start the job. Timing will start on the first copy start button press. Some devices can require
another button to be hit to wake the device, such as a “Power/Sleep” button. The timer starts when the
first button is pressed to wake the device up.
2) If the device is in off state: when the total delay time has elapsed, turn the copy device on using
the power button and simultaneously start the timing device. The time measurement is started
when the device is turned on. In the case that the measured results are the same, quick copy,
or similar features may be used to initiate the copy job. Some copy systems may require some
amount of delay between turning on the copy device and selecting copy start button on the
control panel for the copy job to successfully execute. For such systems, the delay used shall be
noted in the full report.
f) Record the time in seconds for completion of the page (the test page has been fully ejected from the
device) to at least two decimal places, and optionally start a timing device for the delay time for the
next test run.
g) Determine which steps to run next.
1) If the timing device for the delay time was started in step c), run steps c) – f) once more for a
total of 2 measurements before continuing to step h).
2) If the timing device for the delay time was not started in step c), run steps a) – f) once more for
a total of 2 measurements before continuing to step h).
h) Determine if the results are consistent according to 5.3.2, and perform a third test run of steps a) –
f) if required.
i) Calculate the average sFCOT .

5.2.4 “1 copy” test from off
The procedure to measure sFCOT is defined by the following steps.
off
a) Make a copy job at the device using page A of the test targets and the same copy mode settings as
the current test run.
NOTE 1 The intent is to enable pressing just the copy start button to begin the copy job.
b) Place the device in off state by turning the device off using the power button on the device and start
a timing device for the delay time.
c) Wait until no earlier than 5 min before the delay time has elapsed before continuing.
d) When the delay time has elapsed, turn the copy device on using the power button and simultaneously
start the timing device. The time measurement is started when turning on the device.
e) As soon as copy UI is functional, configure the copy job again using the same settings as the current
test run.
f) Select the copy start button on the control panel. In the case that the measured results are the
same, the quick copy, or similar features may be used to initiate the copy job. Some copy systems

may require some amount of delay between turning on the copy device and selecting the copy start
button on the control panel. For such systems, the delay used shall be noted in the full report.
g) Record the time in seconds for completion of the page (the test page has been fully ejected from the
device) to at least two decimal places.
h) Run steps b) – g) twice.
i) Determine if the results are consistent according to 5.3.2, and perform a third test run of steps b) –
g) if required.
j) Calculate the average sFCOT .

5.2.5 “1 copy + 30 seconds” test from ready
The procedure to measure sESAT and sEFTP is defined by the following steps.
30sec 30sec
a) Enter copy set count = 1 and press the copy start button. Start the ready delay timer when the page
has fully exited from the device.
NOTE 1 Step a) is skipped when the ready delay timer is started at the end of a different test.
b) Enter copy count = N required for sLCOT – sFCOT ≥ 30 s. For the second and third tests, use
30sec 30sec
the same copy count as used in the first test.
NOTE 2 This sFCOT is not the same as sFCOT from the 1 copy test. The sFCOT measured is
30sec 1copy 30sec
used to verify sLCOT – sFCOT ≥ 30 s and to calculate sESAT .
30sec 30sec 30sec
c) [Start test run] At the end of the ready delay time, press the copy start button and simultaneously
start the timing device (watch or otherwise).
d) Record the time for completion of the sFCOT to at least two decimal places. This is the time
30sec
from pressing the copy button until the first copy is fully ejected from the machine. If the output
paper bin capacity is less than the number of pages to be copied, remove the output paper during
the test.
e) Record the time for completion of the sLCOT to at least two decimal places and start the ready
30sec
delay timer. This is the time from pressing the copy button until the last copy is fully ejected from
the machine.
f) [End test run]
g) Run the 1 copy + 30 Seconds test steps b) – f) twice. Calculate sESAT and sEFTP for each
30sec 30sec
test run according to Clause 6.
h) Determine if the results are consistent within ±5 % according to 5.3.2 and perform a third test
run if required. (The data from the test is average of the individual runs. Three iterations are the
maximum and the results from all iterations are averaged to get the required data.)
i) Calculate the average sESAT and sEFTP for the current test target according to Clause 6.
