Note: Stakeholders requested more differentiation between Professional Imaging Products and nonProfessional Imaging Products through additions to the definition.

76B) Marking Technologies:

77
78

One stakeholder stated that Professional Imaging Products do not necessarily produce deliverables forsale (if used in internal print shops) and suggested EPA define these products with technical criteria (i.e.
products intended for high volume and a broader range of paper sizes and weights, including special
paper media), including an additional criterion for input power greater than 2000 W due to heavier paper.
Another stakeholder recommended to change the definition from "three of the following additionalfeatures" to two, and add IDEAlliance Digital Press Certification and FOGRA Validation Printing System
Certification, as GRACol is not a certification.
EPA reviewed 27 professional products and 11 high-end office products to validate the efficacy of thedefinition criteria, and found that many of the optional criteria do not adequately differentiate these two
types of products. To ensure that products are not miscategorized, EPA proposes that products meet fiveof the optional criteria (paragraphs g) through m) of the definitions). EPA also replaced the previous
requirement for "case binding" (which EPA understands is the process for assembling a hardcover book)with "perfect binding" (which is the process for a softcover book and is much more common acrossprofessional products), and added a provision for similar binding technologies.
Stakeholders provided additional comments on the definitions, but EPA has not made any additional
edits. Specifically:- While professional imaging products do not always produce deliverables for sale, they are marketed assuch (EPA did not find models solely marketed for internal print shops);- There are already criteria regarding print volume (print speed and capacity), paper size, paper weight,
and coated paper;- A power criterion could inadvertently lock in high power draw.

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

Page 2 of 25

83
84
85
86
87
88

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,
development of the image with particles of toner using the latent image on the photoconductor todefine the presence or absence of toner at a given location, transfer of the toner to the final print
media, and fusing 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.

89
90

includes Dot Formed Impact and Fully Formed Impact.

92
93
94
95
96

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.

97
98
99
100

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.

101
102
103

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.

104
105

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.

110C) Operational Modes:

1111) On Mode:

112
113

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.

114
115
116
117
118
119

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).

125

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

127
128
129
130
131
132
133
134

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.

to the Imaging Equipment.
a) A DFE offers three or more of the following advanced features:
i.
ii.
iii.
iv.
v.
vi.
vii.

Network connectivity in various environments;
Mailbox functionality;
Job queue management;
Machine management (e.g., waking the Imaging Equipment from a reduced powerstate);
Advanced graphic user-interface (UI);
Ability to initiate communication with other host servers and client computers (e.g.,scanning to email, polling remote mailboxes for jobs); or
Ability to post-process pages (e.g., reformatting pages prior to printing).

175
176
177
178
179

b) Type 1 DFE: A DFE that draws its dc power from its own ac power supply (internal orexternal), which is separate from the power supply that powers the Imaging Equipment. This
DFE may draw its ac power directly from a wall outlet, or it may draw it from the ac power
associated with the Imaging Equipment’s internal power supply. A Type 1 DFE may be soldstandard with the Imaging Equipment product or as an accessory.

180
181
182
183
184

c) Type 2 DFE: A DFE that draws its dc power from the same power supply as the Imaging
Equipment with which it operates. Type 2 DFEs must have a board or assembly with aseparate processing unit that is capable of initiating activity over the network and can bephysically removed, isolated, or disabled using common engineering practices to allow power
measurements to be made.

185d) Professional Digital Front-end (DFE): A DFE which meets all of the following criteria:

Is sold with a product defined above as a Professional Imaging Product;has processor performance per socket 2 equal to or greater than 20;
provides support for buffered memory (including both buffered dual in-line memory
modules (DIMMs) and buffered on board (BOB) configurations).
is packaged and sold with one or more ac-dc or dc-dc power supplies; andis designed such that all processors have access to shared system memory.

Note: One stakeholder suggested that EPA require at least 6 of the features mentioned in the broader
DFE definition, instead of the servers-specific criteria in the proposed Professional DFE definition, suchas error-correcting codes (ECC) and buffered memory. Another stakeholder supported removing the ECC
criterion.
The Professional DFE definition is intended to differentiate server-based DFEs, and the broader DFE
criteria do not do this, no matter how many of them are required. EPA is therefore proposing to keep aseparate Professional DFE definition. EPA agrees with stakeholders that ECC should be removed fromthe definition because it does not reliably filter out workstation-based systems, and is proposing to makethis change in the Final Draft.

203
204

e) Auxiliary Processing Accelerator (APA): A computing expansion add-in card installed in a
general-purpose add-in expansion slot of the DFE (e.g., GPGPU installed in a PCI slot).

205
206

6) Network Connection: A connection that permits the exchange of information between the Imaging
Equipment and one or more external powered devices.

2 Processor performance per socket = [# of processor cores] x [processor clock speed (GHz)], where # ofcores represents the number of physical cores and processor clock speed represents the Max TDP corebase frequency for a given processor.

219
220

10) Marking Engine: The fundamental engine of an Imaging Equipment product that drives image
production. A marking engine relies upon functional adders for communication ability and image
processing. Without functional adders and other components, a marking engine cannot acquire
image data for processing and is non-functional.

221

Note: Multiple stakeholders were concerned with the exclusion of Professional Imaging Products from thescope of Version 3.0 and recommended:- Removing the scope exclusion for Professional Imaging Products; and- Providing a transitional period to avoid products from changing ENERGY STAR certification status.
Due to continuing uncertainty regarding testing of professional products and to avoid these products fromlosing their certification, EPA proposes to include them in the scope of the Version 3.0 specification andhas added them to Table 1, above, and removed them from the list of excluded products in Section 2.2.2,
below.
Moreover, EPA has added a new section of requirements applicable only to Professional Products in
Section 3.4, below. These extend the Version 2.0 TEC requirements for professional products until a
Version 4.0 specification revision, to be developed once the test method is finalized in the near future.

v. Imaging Equipment products with DFEs that fail to meet these requirements may be certified
without subtracting or excluding the DFE power from that of the Imaging Equipment productas a whole. The combined energy consumption of the DFE and the Imaging Equipment must
be below the appropriate requirement.

322
323
324
325
326
327

Note: One stakeholder commented that the DFE requirement is too strict, arguing if a DFE does not meetthe requirements, then the DFE power should not to be subtracted but counted together with the rest of
the imaging equipment for certification against the requirements. EPA proposes to allow models with
DFEs that do not meet the DFE requirements to nonetheless be certified, as long as the combination ofimaging equipment and DFE energy consumption does not exceed the imaging equipment requirements.
This will provide more flexibility to manufacturers without impacting overall energy consumption.

Default Delay Time Requirements for Non-Professional Imaging Products: Measured Default
Delay Time to Sleep (tDEFAULT) shall be less than or equal to the Required Default Delay Time to
Sleep (tDEFAULT_REQ) requirement specified in Table 3, subject to the following conditions:i.

When reporting data and certifying 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 certification purposes; however, the default-delay
time provided must correspond with whichever level is used.
ii. Default Delay Time does not apply to OM products that can meet Sleep Mode requirements
in Ready State.
iii. The Default Delay Time to Sleep may not be adjusted by the user to be greater than the
Maximum Delay Times to Sleep Adjustable by the User, as specified in Table 4.

3.3.2

Typical Electricity Consumption: Calculated Typical Electricity Consumption (TEC2017) per
Equation 3 or Equation 4 shall be less than or equal to the Maximum TEC Requirement (TECREQ)
specified in Equation 6.
i.

For Imaging Equipment with a Type 2 DFE that meets 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. For Imaging Equipment with a DFE that does not meet the DFE maximum TECDFE
requirement, the measured TEC value must meet the TECMAX without any subtractions or
exclusions for the DFE.
iii. The DFE shall not interfere with the ability of the Imaging Equipment to enter or exit its lowerpower modes.

Note: EPA has added Section 3.3.2.ii to note that for those products where the DFE does not meet the
ENERGY STAR requirements, there is still a pathway to certification, if the products total energy
consumption (the imaging equipment plus the DFE energy use) is less than the appropriate TECMAX level.
In addition, EPA has removed the clause that stated, “The energy use of a DFE can only be excluded if itmeets the Type 2 DFE definition in Section 1 and is a separate processing unit that is capable of initiating
activity over the network.” EPA found this to be redundant information and requests comment if thisprovides any additional utility to stakeholders. This change has been carried over to the other sections of
the draft specification.

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 certification.
iv. For printers, digital duplicators with print capability, and MFDs with print capability, TEC shallbe calculated per Equation 3.

TECMAX to 0.01 kWh for reporting.

Table 6: TEC Requirement

A stakeholder commented that wireless technology includes a broader range of capabilities, including
access points which are always active; as such, the Wi-Fi adder for TEC products should be equivalent to
1 watt. As Wi-Fi functionality may not be turned off by default, either due to easier usability or function as
an access point, EPA proposes to extend the previously proposed Wi-Fi allowance to all models with thefunctionality enabled during the test even if they also support and are connected via Ethernet.

Note: Two stakeholders commented that the TEC requirements did not meet a 25% pass rate in two
speed bins and requested that the rates be adjusted to meet the top quartile in all bins. In response, EPA
has proposed a slight decrease in the stringency of the requirements to maintain sufficient product choice
across types and speed categories. EPA estimates that 31% of products in the dataset meet the criteria.
This includes roughly the top quartile in all of the major speed bins, where most product is located. EPA
also reviewed the difference in pass rates for non-A3 and A3 products and found that roughly 29% of all
non-A3 products and 33% of all A3 products meet the criteria. Per stakeholder feedback, EPA also
reviewed spec sheets to determine if there was a negative impact on the feature sets based on thecriteria and did not find any correlation. Finally, EPA found that of the 22 product brand owners with a
TEC product, 16 have at least one product meeting the criteria. As such, EPA believes that the criteria
listed above will effectively differentiate products on the market as well as provide consumer choice.

Note: One stakeholder questioned whether EPA harmonized with Blue Angel in regards to Recovery
Time while another pointed out that he maximum default delay time to qualify for the longer recovery timein the speed bin of 20 < s ≤ 30 should be 30 s, not 45 s. EPA has revised the error in Table 7. EPA has
also amended Table 7 so that it takes into account the limitations outlined in Table 3 of the specification.
While this no longer harmonizes with the tables found in the Blue Angel specification, EPA believes thisgives better clarity on the requirements for ENERGY STAR.
In addition, stakeholders were confused by the former table headings, which read “Maximum Default
Delay Time to Sleep to Permit Applicability of Shorter/Longer Recovery Time in Equation 8/9 (min)”. It
was unclear whether this referred to a) the Default Delay Time to Sleep or b) the Maximum Default Delay
Time to Sleep Adjustable by the User. EPA has clarified the headings to make it clear that it is the Default
Delay Time that determines the applicable Recovery Time requirements.

Finally, one stakeholder noted a potential discrepancy between Table 3 (Required Default Delay Time to
Sleep) and Table 7 (Determination of Recovery Time, which takes Default Delay Time as an input).
Specifically, Table 3 requires:• Printers and digital duplicators without copying capability with speeds less than or equal 10 ipm tohave Default Delay Time to Sleep less than or equal to 5 minutes, and• All products with speeds greater than 50 to have Default Delay Time to Sleep less than 45 minutes.

requirement specified in Table 8 for the given DFE type.
i.
ii.

For Type 1 DFEs that meet the relevant TECDFE requirement, the DFE should be excluded
from the TEC energy
For Type 2 DFEs that meet the relevant TECDFE requirement, the TEC value of the DFE
should be subtracted from the TEC energy measurements of the Imaging Equipment product.

iii. For Imaging Equipment with a DFE that does not meet the DFE maximum TECDFE
requirement, the measured TEC value must meet the TECMAX without any exclusions for the
DFE.

products;
v. Imaging Equipment products with Type 2 DFEs that fail to meet these requirements may becertified without subtracting the DFE power from that of the Imaging Equipment product as awhole. The combined energy consumption of the DFE and the Imaging Equipment must be
below the appropriate requirement.

Note: One stakeholder commented that the DFE requirement is too strict, arguing if a DFE does not meetthe requirements, then the DFE power should not to be subtracted but counted together with the rest of
the imaging equipment for certification against the requirements. EPA proposes to allow models with
DFEs that do not meet the DFE requirements to nonetheless be certified, as long as the combination ofimaging equipment and DFE energy consumption does not exceed the imaging equipment requirements.
This will provide more flexibility to manufacturers without impacting overall energy consumption.

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 Mode, 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

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.
