Product Specification for Imaging Equipment
Eligibility Criteria
Version 2.0
Rev. Jun-2013
Following is the Version 2.0 ENERGY STAR Product Specification for Imaging Equipment. A product shallmeet all of the identified criteria if it is to earn the ENERGY STAR.

1 DEFINITIONSA) Product Types:
1) Printer: A product whose primary function is to generate paper output from electronic input. A
printer is capable of receiving information from single-user or networked computers, or other input
devices (e.g., digital cameras). This definition is intended to cover products that are marketed as
printers, and printers that can be field-upgraded to meet the definition of an MFD.
2) Scanner: A product whose primary function is to convert paper originals into electronic images
that can be stored, edited, converted, or transmitted, primarily in a personal computing
environment. This definition is intended to cover products that are marketed as scanners.
3) Copier: A product whose sole function is to produce paper duplicates from paper originals. Thisdefinition is intended to cover products that are marketed as copiers, and upgradeable digitalcopiers (UDCs).
4) Facsimile (Fax) Machine: A product whose primary functions are (1) to scan paper originals forelectronic transmission to remote units, and (2) to receive electronic transmissions for conversion
to paper output. A fax machine may also be capable of producing paper duplicates. Electronictransmission is primarily over a public telephone system, but may also be via a computer networkor the Internet. This definition is intended to cover products that are marketed as fax machines.
5) Multifunction Device (MFD): A product that performs two or more of the core functions of a Printer,
Scanner, Copier, or Fax Machine. An MFD may have a physically integrated form factor, or it may
consist of a combination of functionally integrated components. MFD copy functionality is
considered to be distinct from single-sheet convenience copying functionality sometimes offeredby fax machines. This definition includes products marketed as MFDs, and “multi-function
products” (MFPs).
6) Digital Duplicator: A product sold as a fully-automated duplicator system through the method of
stencil duplicating with digital reproduction functionality. This definition is intended to coverproducts that are marketed as digital duplicators.
7) Mailing Machine: A product whose primary function is to print postage onto mail pieces. Thisdefinition is intended to cover products that are marketed as mailing machines.
B) Marking Technologies:
1) Direct Thermal (DT): A marking technology characterized by the burning of dots onto coated print
media that is passed over a heated print head. DT products do not use ribbons.

ENERGY STAR Program Requirements for Imaging Equipment – Eligibility Criteria (Rev. Jun-2013)

Page 1 of 18

2) Dye Sublimation (DS): A marking technology characterized by the deposition (sublimation) of dye
onto print media as energy is supplied to heating elements.
3) Electro-photographic (EP): A marking technology characterized by the illumination of aphotoconductor in a pattern representing the desired output image via a light source, developmentof the image with particles of toner using the latent image on the photoconductor to define thepresence or absence of toner at a given location, transfer of the toner to the final print media, andfusing to cause the output to become durable. For purposes of this specification, Color EP
products simultaneously offer three or more unique toner colors, while Monochrome EP products
simultaneously offer one or two unique toner colors. This definition includes Laser, Light Emitting
Diode (LED), and Liquid Crystal Display (LCD) illumination technologies.
4) Impact: A marking technology characterized by the formation of the desired output image bytransferring colorant from a “ribbon” to the print media via an impact process. This definition
includes Dot Formed Impact and Fully Formed Impact.
5) Ink Jet (IJ): A marking technology characterized by the deposition of colorant in small drops
directly to the print media in a matrix manner. For purposes of this specification, Color IJ products
offer two or more unique colorants at one time, while Monochrome IJ products offer one colorant
at a time. This definition includes Piezo-electric (PE) IJ, IJ Sublimation, and Thermal IJ. Thisdefinition does not include High Performance IJ.
6) High Performance IJ: An IJ marking technology that includes nozzle arrays that span the width ofa page and/or the ability to dry ink on the print media via supplemental media heating
mechanisms. High-performance IJ products are used in business applications usually served byelectro-photographic marking products.
7) Solid Ink (SI): A marking technology characterized by ink that is solid at room temperature andliquid when heated to the jetting temperature. This definition includes both direct transfer andoffset transfer via an intermediate drum or belt.
8) Stencil: A marking technology characterized by the transfer of images onto print media from astencil that is fitted around an inked drum.
9) Thermal Transfer (TT): A marking technology characterized by the deposition of small drops ofsolid colorant (usually colored waxes) in a melted/fluid state directly to print media in a matrix
manner. TT is distinguished from IJ in that the ink is solid at room temperature and is made fluidby heat.
C) Operational Modes:
1) On Mode:a) Active State: The power state in which a product is connected to a power source and isactively producing output, as well as performing any of its other primary functions.
b) Ready State: The power state in which a product is not producing output, has reachedoperating conditions, has not yet entered into any lower-power modes, and can enter Active
State with minimal delay. All product features can be enabled in this state, and the product isable to return to Active State by responding to any potential inputs, including external
electrical stimulus (e.g., network stimulus, fax call, or remote control) and direct physicalintervention (e.g., activating a physical switch or button).

ENERGY STAR Program Requirements for Imaging Equipment – Eligibility Criteria (Rev. Jun-2013)

Page 2 of 18

2) Off Mode: The power state that the product enters when it has been manually or automaticallyswitched off but is still plugged in and connected to the mains. This mode is exited whenstimulated by an input, such as a manual power switch or clock timer to bring the unit into Ready
State. When this state is resultant from a manual intervention by a user, it is often referred to as
Manual Off, and when it is resultant from an automatic or predetermined stimuli (e.g., a delay timeor clock), it is often referred to as Auto-off.1
3) Sleep Mode: A reduced power state that a product enters either automatically after a period ofinactivity (i.e., Default Delay Time), in response to user manual action (e.g., at a user-set time ofday, in response to a user activation of a physical switch or button), or in response to external
electrical stimulus (e.g., network stimulus, fax call, remote control). For products evaluated under
the TEC test method, Sleep Mode permits operation of all product features (including
maintenance of network connectivity), albeit with a possible delay to transition into Active State.
For products evaluated under the OM test method, Sleep Mode permits operation of a single
active network interface, as well as a fax connection if applicable, albeit with a possible delay totransition into Active State.
4) Standby: The lowest power consumption state which cannot be switched off (influenced) by theuser and that may persist for an indefinite time when the product is connected to the mainelectricity supply and used in accordance with the manufacturer’s instructions.1,2 Standby is the
product’s minimum power state. For Imaging Equipment products addressed by this specification,
the “Standby” Mode usually corresponds to Off Mode, but may correspond to Ready State or
Sleep Mode. A product cannot exit Standby and reach a lower power state unless it is physicallydisconnected from the main electricity supply as a result of manual manipulation.
D) Media Format:
1) Large Format: Products designed for A2 media and larger, including those designed toaccommodate continuous-form media greater than or equal to 406 mm wide. Large-format
products may also be capable of printing on standard-size or small-format media.
2) Standard Format: Products designed for standard-sized media (e.g., Letter, Legal, Ledger, A3,
A4, B4), including those designed to accommodate continuous-form media between 210 mm and406 mm wide. Standard-size products may also be capable of printing on small-format media.
a) A3-capable: Standard Format products with a paper path width equal to or greater than
275 mm.
3) Small Format: Products designed for media sizes smaller than those defined as Standard (e.g.,
A6, 4”x6”, microfilm), including those designed to accommodate continuous-form media less than
210 mm wide.
4) Continuous Form: Products that do not use a cut-sheet media format and that are designed for
applications such as printing of bar codes, labels, receipts, banners, and engineering drawings.
Continuous Form products can be Small, Standard, or Large Format.
E) Additional Terms:
1) Automatic Duplexing: The capability of a copier, fax machine, MFD, or printer to produce images
on both sides of an output sheet, without manual manipulation of output as an intermediate step.
A product is considered to have automatic duplexing capability only if all accessories needed to
produce duplex output are included with the product upon shipment.

1 For the purposes of this specification “mains” or the “main electricity supply” refers to the input powersource, including a dc power supply for products that operate solely off dc power.

3.3.2

If a product is not certain to be bundled with an automatic duplex tray, the partner must makeclear in their product literature, on their Web site, and in institutional sales literature that
although the product meets the ENERGY STAR energy efficiency requirements, the productonly fully qualifies for ENERGY STAR when bundled with or used with a duplexer tray. EPA
asks that partners use the following language to convey this message to customers:"Achieves ENERGY STAR energy savings; product fully qualifies when packaged with (orused with) a duplex tray."

Typical Electricity Consumption: Calculated Typical Electricity Consumption (TEC) per Equation 3
or Equation 4 shall be less than or equal to the Maximum TEC Requirement (TECMAX) specified in
Equation 6.
i.

For Imaging Equipment with a Type 2 DFE that meet the Type 2 DFE maximum TECDFE
requirement in Table 2, the measured energy consumption of the DFE shall be divided by
0.80 to account for internal power supply losses and then excluded when comparing the
product’s measured TEC value to TECMAX and for reporting.
ii. The DFE shall not interfere with the ability of the Imaging Equipment to enter or exit its lowerpower modes.
iii. The energy use of a DFE can only be excluded if it meets the Type 2 DFE definition in Section
1 and is a separate processing unit that is capable of initiating activity over the network.

Example: A printer’s total TEC result is 24.50 kWh/wk and its Type 2 TECDFE value calculated in Section
3.2.4 is 9.0 kWh/wk. The TECDFE value is then divided by 0.80 to account for internal power supply losses
with the Imaging Equipment in Ready State, resulting in 11.25 kWh/wk. The power supply adjusted value
is subtracted from the tested TEC value: 24.50 kWh/wk – 11.25 kWh/wk = 13.25 kWh/wk. This
13.25 kWh/wk result is then compared to the relevant TECMAX to determine qualification

iv. For printers, fax machines, digital duplicators with print capability, and MFDs with print
capability, TEC shall be calculated per Equation 3.

Standby Requirements: If the resultant power in Paragraph i, above, is less than or equal
to the Ready State, Sleep Mode, or Off Mode power of the Imaging Equipment as awhole, then the power shall be excluded from the Ready State, Sleep Mode, or Off Modepower of the Imaging Equipment product as a whole when comparing to the Standby
requirements in Section 3.4.5, below, and for reporting.
Otherwise, the Sleep Mode power of the DFE, as measured in the test method, shall be
divided by 0.60 and excluded from the Ready State,Sleep Mode, or Off Mode power of
the Imaging Equipment for comparing to the requirements, and for reporting.

ii.

The DFE must not interfere with the ability of the Imaging Equipment to enter or exit its lowerpower modes.
iii. In order to take advantage of this exclusion, the DFE must meet the Type 2 DFE definition in
Section 1 and be a separate processing unit that is capable of initiating activity over the
network.
Examples: Product 1 is an Imaging Equipment product whose Type 2 DFE has no distinct sleep mode.
The Type 2 DFE has measured Ready State and Sleep Mode power both equal to 30 watts. The
measured Sleep Mode power of the product is 53 watts. When subtracting 50 watts (30 watts / 0.60) fromthe measured Sleep Mode power of the product, 53 watts, the resulting 3 watts is the Sleep Mode powerof the product for use in the criteria limits below.
Product 2 is an Imaging Equipment product whose Type 2 DFE goes to sleep when the Imaging
Equipment goes to sleep during testing. The Type 2 DFE has measured DFE Ready State and Sleep
Mode power equal to 30 watts and 5 watts, respectively. The measured Sleep Mode power of the productis 12 watts. When subtracting 50 watts (30 watts / 0.60) from the measured Sleep Mode power of the
product, 12 watts, the result is -38 watts. In this case, instead subtract 8.33 watts (5 watts / 0.60) from themeasured Sleep Mode power of the product, 12 watts, resulting in 3.67 watts which is used in the criteria
limits below.
3.4.3

Default Delay Time: Measured Default Delay Time to Sleep (tSLEEP) shall be less than or equal to
the Required Default Delay Time to Sleep (tSLEEP_REQ) requirement specified in Table 6, subject tothe following conditions:i.

The Default Delay Time to Sleep may not be adjusted by the user to be greater than the
Maximum Machine Delay Time. This Maximum Machine Delay Time shall be set by the
manufacturer at less than or equal to 4 hours.
ii. When reporting data and qualifying products that can enter Sleep Mode in multiple ways,
partners should reference a Sleep level that can be reached automatically. If the product iscapable of automatically entering multiple, successive Sleep levels, it is at the manufacturer’s
discretion which of these levels is used for qualification purposes; however, the default-delay
time provided must correspond with whichever level is used.
iii. Default Delay Time does not apply to OM products that can meet Sleep Mode requirements inReady State.

determined per Equation 7, subject to the following conditions:i.

Only those interfaces that are present and used during the test, including any fax interface,
may be considered functional adders.
ii. Product functionality offered through a DFE shall not be considered a functional adder.
iii. A single interface that performs multiple functions may be counted only once.

4 TESTING
4.1 Test Methods
4.1.1

When testing Imaging Equipment products, the test methods identified in Table 10 shall be used
to determine qualification for ENERGY STAR.
Table 10: Test Methods for ENERGY STAR Qualification
Product TypeAll Products

Test Method
ENERGY STAR Imaging Equipment Test Method, Rev. Jun-2013

4.2 Number of Units Required for Testing
4.2.1

4.2.2

Representative Models shall be selected for testing per the following requirements:i.

For qualification of an individual product model, a product configuration equivalent to thatwhich is intended to be marketed and labeled as ENERGY STAR is considered theRepresentative Model;ii.

For qualification of a product family that does not include a Type 1 DFE, the highest energy
using configuration within the family shall be considered the Representative Model. Any
subsequent testing failures (e.g., as part of verification testing) of any model in the family
will have implications for all models in the family.

iii.

For qualification of a product family that includes Type 1 DFE, the highest energy using
configuration of the Imaging Equipment and highest energy using DFE within the family
shall be tested for qualification purposes. Any subsequent testing failures (e.g., as part ofverification testing) of any model in the family and all Type 1 DFEs sold with the Imaging
Equipment, including those not tested with the Imaging Equipment product, will have
implications for all models in the family. Imaging Equipment products that do notincorporate a Type 1 DFE may not be added to this product family for qualification and must
be qualified as a separate family without a Type 1 DFE.

A single unit of each Representative Model shall be selected for testing.

4.3 International Market Qualification
4.3.1

Products shall be tested for qualification at the relevant input voltage/frequency combination foreach market in which they will be sold and promoted as ENERGY STAR.

5 USER INTERFACE
5.1.1

Manufacturers are encouraged to design products in accordance with the user interface standard
IEEE 1621: Standard for User Interface Elements in Power Control of Electronic Devices
Employed in Office/Consumer Environments. For details, see http://eetd.LBL.gov/Controls.

6 EFFECTIVE DATE
6.1.1

Effective Date: The Version 2.0 ENERGY STAR Imaging Equipment specification shall take effecton January 1, 2014. To qualify for ENERGY STAR, a product model shall meet the ENERGYSTAR specification in effect on its date of manufacture. The date of manufacture is specific toeach unit and is the date on which a unit is considered to be completely assembled.

6.1.2

Future Specification Revisions: EPA reserves the right to change this specification should
technological and/or market changes affect its usefulness to consumers, industry, or theenvironment. In keeping with current policy, revisions to the specification are arrived at throughstakeholder discussions. In the event of a specification revision, please note that the ENERGYSTAR qualification is not automatically granted for the life of a product model.

6.1.3

Items for Consideration in a Future Revision:i.

Test Method Changes: EPA and DOE will continue to monitor the implementation ofproxying capability in Imaging Equipment hardware and consider the development of a test
method to determine the presence of a network proxy (e.g., one compliant with ECMA-393
ProxZzzy for Sleeping Hosts). EPA and DOE will also evaluate the possibility of measuring
and reporting as-shipped product speed, recovery time from Sleep or Off Modes for OM
products, and wakeup from Sleep Mode caused by common network events.

ii.

TEC Requirements in Kilowatt-hours per Year: EPA has added columns to the TEC Tables
expressing the requirements in kilowatt-hours per year in addition to the currently-usedkilowatt-hours per week. Although this is purely informative, EPA will consider making this unit
the only way to express TEC in a future specification revision as a way to address issues with
reporting accuracy and comparisons between other ENERGY STAR products (which typicallyreport in kilowatt-hours/year).

iii. Equipment for Printing and Scanning Media Other than Paper: EPA often receives
questions about qualifying products that print or scan media other than paper (e.g., cloth,
microfilm, etc.) and welcomes data on their energy consumption. Such data would support
development of requirements for these products in a future version of the specification.
iv. Professional Products (High-speed TEC Products for Printing on Heavier, Larger
Paper): EPA has learned that some high-speed TEC products have additional requirements
for handling larger and heavier paper. EPA will consider separating these into a separate
category in a future version of the specification.
v.

Decoupled Requirements for TEC Categories: In Version 1 and 2 Imaging Equipment
specifications, EPA assumed that color products would have higher TEC than monochrome
products due to their additional complexity, and multi-function would have higher TEC thansingle-function. The TEC requirements were structured to reflect this relationship. However,
EPA has recently learned that color MFDs—a premium product—can incorporate energy
saving features that decrease their energy consumption below that for monochrome nonMFDs. EPA will therefore consider decoupling the TEC requirements in the future torecognize the highest performers among all TEC categories.

vi. Scope Reevaluation: EPA may re-assess the current market for Imaging Equipment todetermine whether the current scope of included products is still relevant and whether
ENERGY STAR label continues to provide a market differentiation for all product classes
included in scope.
vii. Expanding Duplexing Requirements: EPA may re-assess the requirements for thepresence of duplexing as integral to the base product and consider how the optional
requirements could be made more stringent. Changing the requirements to result in greater
coverage of products with duplexing integral to the base marking engine could reduce paper
usage.
