only if the dc source is the only acceptable source of power for the product (i.e., no ac plug or
EPS is available).
2) Products powered by low-voltage dc shall be configured with an ac source of the dc power for
testing (e.g., an ac-powered universal serial bus (USB) hub).
a) The ac source of the dc power used for testing shall be recorded and reported for all tests.
3) Power for the unit under test (UUT) shall include the following, as measured per Section 5 of thismethod:a) Ac power consumption of the low-voltage dc source with the UUT as the load (PL); andb) Ac power consumption of the low-voltage dc source with no load (PS).

Where:• NIMAGES is the number of images per job, rounded down
(truncated) to the nearest integer,• s is the product speed in images per minute (ipm), calculated in
section 6.1.B), of this test procedure, and• NJOBS is the number of jobs per day, as calculated perTable 7.
C) Test Image: Test Pattern A from International Organization for Standardization (ISO)/IEC Standard
10561:1999 shall be used as the original image for all testing.
1) Test images shall be rendered in 10 point size in a fixed-width Courier font (or nearest
equivalent).
2) German-specific characters need not be reproduced if the product is incapable of German
character reproduction.
D) Print Jobs: Print jobs for the test shall be sent over the network connection designated in Table 6
immediately before printing each job.
1) Each image in a print job shall be sent separately, (i.e., all images may be part of the same
document), but shall not be specified in the document as multiple copies of a single original
image (unless the product is a digital duplicator).
2) For printers and MFDs that can interpret a page description language (PDL) (e.g., PrinterCommand Language PCL, Postscript), images shall be sent to the product in a PDL.
E) Copy Jobs:
1) For copiers with speed less than or equal to 20 ipm, there shall be one original per required
image.
2) For copiers with speed greater than 20 ipm, it may not be possible to match the number ofrequired original images (i.e., due to limits on document feeder capacity). In this case, it ispermissible to make multiple copies of each original, and the number of originals shall be greaterthan or equal to ten.
Example: For a 50 ipm unit that requires 39 images per job, the test may be performed with four
copies of 10 originals or three copies of 13 originals.
3) Originals may be placed in the document feeder before the test begins.
a) Products without a document feeder may make all images from a single original placed on
the platen.
F) Fax Jobs: Fax jobs shall be sent via the connected phone line or line simulator immediately before
performing each job.

Measurement Procedures

A) Measurement of TEC shall be conducted according to Table 8 for printers, fax machines, digital
duplicators with print capability, and MFDs with print capability, and Table 9 for copiers, digital
duplicators without print capability, and MFDs without print capability, subject to the following
provisions:1) Paper: There shall be sufficient paper in the UUT to perform the specified print or copy jobs.
2) Duplexing: Products shall be tested in simplex mode, unless the speed of duplex mode output isgreater than the speed of simplex mode output, in which case they will be tested in duplex mode.
In all cases, the mode in which the unit was tested and the print speed used must be
documented. Originals for copying shall be simplex images.
3) Energy Measurement Method: All measurements shall be recorded as accumulated energy overtime, in Wh; all time shall be recorded in minutes.
a) “Zero meter” references may be accomplished by recording the accumulated energy
consumption at that time rather than physically zeroing the meter.

9 OPERATIONAL MODE (OM) TEST PROCEDURE
9.1

Measurement Procedures

A) Measurement of OM power and delay times shall be conducted according to Table 10, subject to thefollowing provisions:
1) Power Measurements: All power measurements shall be made using either the average power oraccumulated energy approaches as described below:a) Average Power Method: The true average power shall be measured over the course of auser selected period, which shall be no less than 5 minutes.
i)

For those modes that do not last 5 minutes, the true average power shall be measured
over the mode’s entire duration.

b) Accumulated Energy Approach: If the test instrument is incapable of measuring the trueaverage power, the accumulated energy consumption over the course of a user selectedperiod shall be measured. The test period shall be no less than 5 minutes. The average
power shall be determined by dividing the accumulated energy consumption (in watt-hours)by the time of the test period (in hours).
i)

For those modes that do not last 5 minutes, the accumulated energy consumption shallbe measured over the mode’s entire duration.

c) If the power consumption of the tested mode is periodic, then the test duration shall containone or more complete periods.

Notes:• Step 1 – If the unit has no Ready indicator, use the time at which the power consumption levelstabilizes to the Ready level, and note this detail when reporting the product test data.
• Step 4 – The Default Delay Time shall be measured starting from the completion of the job until
the unit enters Sleep Mode.
• Steps 4 and 5 – For products with more than one Sleep level, repeat these steps as many times
as necessary to capture all successive Sleep levels and report these data. Two Sleep levels are
typically used in large-format copiers and MFDs that use high-heat marking technologies. For
products lacking this Mode, disregard Steps 4 and 5.
• Steps 4 and 5 – For products without a Sleep Mode, perform and record measurements from
Ready Mode.
• Steps 4 and 6 – Default-delay time measurements are to be measured in parallel fashion,
cumulative from the start of Step 4. For example, a product set to enter a Sleep level in 15
minutes and enter a second Sleep level 30 minutes after entering the first Sleep level will have a
15-minute default-delay time to the first level and a 45 minute default-delay time to the second
level.

10 TEST PROCEDURES FOR PRODUCTS WITH A DIGITAL FRONTEND (DFE)
This step applies only to products that have a DFE as defined in Section 1 of the ENERGY STAR
Program Requirements for Imaging Equipment.

10.1 Ready Mode DFE Test
A) Products that are network-capable as-shipped shall be connected during testing. The network
connection used shall be determined using Table 6.
B) If the DFE has a separate main power cord, regardless of whether the cord and controller are internalor external to the imaging product, a 10 minute power measurement of the DFE alone shall be made,and the average power recorded while the main product is in Ready Mode.
C) If the DFE does not have a separate main power cord, the tester shall measure the dc power required
for the DFE when the unit as a whole is in Ready Mode. A 10 minute power measurement of the dc
input to the DFE shall be made, and the average power recorded while the main product is in Ready
Mode. This will most commonly be accomplished by taking an instantaneous power measurement of
the dc input to the DFE.

10.2 Sleep Mode DFE Test
This testing shall be performed to obtain the Sleep Mode power of a DFE device over a 1 hour period.
The resulting value will be used to qualify Imaging Equipment products that incorporate DFEs with
network-capable Sleep Modes.
A) Products that are network-capable as-shipped shall be connected during testing. The network
connection used shall be determined using Table 6.
B) If the DFE has a separate main power cord, regardless of whether the cord and controller are internalor external to the imaging product, a 1 hour power measurement of the DFE alone shall be made,and the average power recorded while the main product is in Sleep Mode. At the end of the 1 hour
power measurement, a print job shall be sent to the main product to ensure the DFE is responsive.
C) If the DFE does not have a separate main power cord, the tester shall measure the dc power required
for the DFE when the unit as a whole is in Sleep Mode. A 1 hour power measurement of the dc input
to the DFE shall be made, and the average power recorded while the main product is in Sleep Mode.
At the end of the 1 hour power measurement, a print job shall be sent to the main product to ensure
the DFE is responsive.
D) In cases B) and C), the following requirements apply:
1) Manufacturers shall provide information on:a) Whether DFE Sleep Mode is enabled as-shipped; andb) The expected time to sleep of the DFE.
2) If the DFE does not respond to the print request at the end of 1 hour, the Ready Mode power
level measured in the test method shall be reported as the Sleep Mode power.
Note: All information specified or provided by manufacturers for product testing shall be publicly available.
