95
96
97

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).

103

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 stimulus (e.g., a delay
time or clock), it is often referred to as Auto-off. 1

106
107
108
109
110

112

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.

i.

Typical Electricity Consumption: Calculated Typical Electricity Consumption (TEC2018) per
Equation 3 or Equation 4 shall be less than or equal to the Maximum TEC Requirement(TECMAX) specified in Equation 6.

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.

Example: A printer’s total TEC result is 24.50 kWh/wk and its Type 2 TEC DFE 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.

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

Off Mode Power Consumption Off Mode power, as measured in the test procedure, shallbe less than or equal to the Maximum Off Mode power specified in Table 11, subject to thefollowing conditions.

For products that do not have an Off Mode, Sleep Mode power, as measured in the test
procedure, shall be less than or equal to the Maximum Off Mode power.
ii. For products that do not have an Off Mode or Sleep Mode, Ready State power, as measured
in the test procedure, shall be less than or equal to the Maximum Off Mode power.
iii. The Imaging Equipment shall meet the Off Mode Power requirement independent of the stateof any other devices (e.g., a host PC) connected to it.

Test Method

For Professional Imaging Equipment with a Type 1 DFE equipped during testing,separately measure the energy consumed by the DFE, as prescribed in Section 7.1.B ofProfessional Imaging Products Test Method, during each step or sub-step of the procedure
noted in Table 6 therein.

Representative Models shall be selected for testing per the following requirements for
products both sold as new and remanufactured.

For certification 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 certification 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 certification 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 shallbe tested for certification 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 not incorporatea Type 1 DFE may not be added to this product family for certification and must be certified
as a separate family without a Type 1 DFE.
A single unit of each Representative Model shall be selected for testing.

All units/configurations for which a Partner is seeking ENERGY STAR certification, mustmeet the ENERGY STAR requirements. For remanufactured products, the Partner mustassign the certified configurations an identifier in the model name/number that is unique to
ENERGY STAR certified configurations. This identifier must be used consistently inassociation with the certified configurations in marketing/sales materials and on the
ENERGY STAR list of certified products (e.g. model A1234 for baseline configurations andA1234-R for remanufactured ENERGY STAR certified configurations).

International Market Certification
4.3.1

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

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
