Qualifying Criteria for
Imaging Equipment

Version 1.2

Download the PDF version of this document.

Products sold in Canada must meet all Canadian regulatory and safety requirements. Eligible equipment is to be qualified by the U.S. EPA.

In order to promote ENERGY STAR qualified Imaging Equipment in Canada, manufacturers are required to sign a Memorandum of Understanding (MOU) with the US Environmental Protection Agency (EPA). We encourage manufacturers, retailers and distributors to sign a Participant Administrative Arrangement with Natural Resources Canada to take advantage of promotional and communications opportunities provided by the program. More information.

Please note that the U.S. EPA has made changes to the ENERGY STAR qualification process, in particular to include mandatory third party testing. You can find more information about those changes on the following web site: http//www.energystar.gov.

These criteria are the same as the program requirements published on the U.S. ENERGY STAR web site and is provided as information only. Administered by Natural Resources Canada’s Office of Energy Efficiency, the ENERGY STAR program in Canada uses the term Participant to designate companies, organizations and stakeholders who promote the use of the ENERGY STAR mark on products or in promotional and marketing material and activities. This technical specification was modified to include this change. The use of the term Participant is similar in scope to that of Partner, which is used by the EPA ENERGY STAR Program.

Also, EPA and Natural Resources Canada both reserve the right to revise the specification should technological and/or market changes affect its usefulness to consumers or industry or its impact on the environment. A product must meet all of the identified criteria to earn the ENERGY STAR registered trademark.

1) Definitions

Products

  • A. Printer
    A product whose primary function is to generate hard-copy 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.

  • B. Scanner
    A product whose primary function is to convert hard copy 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.

  • C. Copier
    A product whose sole function is to produce hard copy duplicates from hard copy originals. This definition is intended to cover products that are marketed as copiers, and upgradeable digital copiers (UDCs).

  • D. Facsimile (Fax) Machine
    A product whose primary functions are (1) to scan hard copy originals for electronic transmission to remote units, and (2) to receive electronic transmissions for conversion to hard copy output. A fax machine may also be capable of producing hard copy duplicates. Electronic transmission is primarily over a public telephone system, but may also be via a computer network or the Internet. This definition is intended to cover products that are marketed as fax machines.

  • E. 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 offered by fax machines. This definition includes products marketed as MFDs, and multi-function products (MFPs).

  • F. 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 cover products that are marketed as digital duplicators.

  • G. Mailing Machine
    A product whose primary function is to print postage onto mail pieces. This definition is intended to cover products that are marketed as mailing machines.

Marking Technologies

  • H. 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.

  • I. Dye Sublimation (DS)
    A marking technology characterized by the deposition (sublimation) of dye onto print media as energy is supplied to heating elements.

  • J. Electro-photographic (EP)
    A marking technology characterized by the illumination of a photoconductor in a pattern representing the desired hard copy image via a light source, development of the image with particles of toner using the latent image on the photoconductor to define the presence or absence of toner at a given location, transfer of the toner to the final print media, and fusing to cause the hard copy 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.

  • K. Impact
    A marking technology characterized by the formation of the desired hard copy image by transferring colorant from a “ribbon” to the print media via an impact process. This definition includes Dot Formed Impact and Fully Formed Impact.

  • L. 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. This definition does not include High Performance IJ.

  • M. High Performance IJ
    An IJ marking technology that includes nozzle arrays that span the width of a 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 by electro-photographic marking products.

  • N. Solid Ink (SI)
    A marking technology characterized by ink that is solid at room temperature and liquid when heated to the jetting temperature. This definition includes both direct transfer and offset transfer via an intermediate drum or belt.

  • P. Thermal Transfer (TT)
    A marking technology characterized by the deposition of small drops of solid 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 fluid by heat.

Operational Modes, Activities, and Power States

  • Q. On Mode

    1. Active State: The power state in which a product is connected to a power source and is actively producing output, as well as performing any of its other primary functions.
    2. Ready State: The power state in which a product is not producing output, has reached operating 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 is able 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 physical intervention (e.g., activating a physical switch or button).
  • R. Off Mode
    The power state that the product enters when it has been manually or automatically switched off but is still plugged in and connected to the mains. This mode is exited when stimulated 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 time or clock), it is often referred to as Auto-off.*

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

  • S. Sleep Mode
    A reduced power state that a product enters either automatically after a period of inactivity (i.e., Default Delay Time), in response to user manual action (e.g., at a user-set time of day, 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 all product features considered Primary Function adders, albeit with a possible delay to transition into Active State.

  • T. Standby
    The lowest power consumption state which cannot be switched off (influenced) by the user and that may persist for an indefinite time when the product is connected to the main electricity supply and used in accordance with the manufacturer’s instructions.* ** 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 physically disconnected from the main electricity supply as a result of manual manipulation.

    *For the purposes of this specification “mains” or the “main electricity supply” refers to the input power source, including a DC power supply for products that operate solely off DC power.
    ** IEC 62301 Ed. 1.0 – Household electrical appliances – Measurement of standby power.

Media Format

    Monochrome Product Speed, s, as Calculated in the Test Method (ipm) Automatic Duplexing Requirement
    s ≤ 24 None
    24 < s > 45 Integral to the base product or offered as an optional accessory
    s ≥ 45 Integral to the base product
3.3.2

Typical Electricity Consumption

  1. Calculated Typical Electricity Consumption (TEC) per Equation 1 or Equation 2 shall be less than or equal to the Maximum TEC Requirement (TECMAX) specified in Table 5, to the nearest 0.1 kilowatt-hour.

  2. For imaging products with a Type 2 DFE, the energy consumption of the DFE, calculated per the example below, should be excluded when comparing the product’s measured TEC value to TECMAX. The DFE must not interfere with the ability of the imaging product to enter or exit its lower-power modes. In order to take advantage of this exclusion, the DFE must meet the definition in Section 1) and be a separate processing unit that is capable of initiating activity over the network.

    Example: A printer’s total TEC result is 24.5 kWh/week and its internal DFE consumes 50W in Ready mode. 50W x 168 hours/week = 8.4 kWh/week, which is then subtracted from the tested TEC value: 24.5 kWh/week – 8.4 kWh/week = 16.1 kWh/week. 16.1 kWh/week is then compared to the following criteria.

3.4 Requirements for Operational Mode (OM) Products

3.4.1

Multiple Sleep Modes: If a product is capable of automatically entering multiple successive Sleep Modes, the same Sleep Mode shall be used to determine qualification under the default delay time to sleep requirements specified in Section 3.4.3 and the Sleep Mode power consumption requirements specified in Section 3.4.4.

3.4.2

DFE Requirements: For imaging products with a functionally-integrated DFE that relies on the imaging product for its power, the power consumption of the DFE should be excluded when comparing the product’s measured Sleep Mode power to the combined marking-engine and functional-adder criteria limits below and when comparing the measured Standby Mode power to the Standby criteria limits below. The DFE must not interfere with the ability of the imaging product to enter or exit its lower-power modes. In order to take advantage of this exclusion, the DFE must meet the definition in Section 1) and be a separate processing unit that is capable of initiating activity over the network.

3.4.3
  1. Measured Default Delay Time to Sleep (tSLEEP) shall be less than or equal to the Maximum Default Delay Time to Sleep (tSLEEP_MAX) requirement specified in Table 6 and Table 7
  2. All OM products must be shipped with a maximum machine delay less than or equal to 4 hours, which is only adjustable by the manufacturer. This maximum machine delay time cannot be influenced by the user and typically cannot be modified without internal, invasive product manipulation.
  3. 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 is capable 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.

3.4.4

Sleep Mode Power Consumption: Measured Sleep Mode power consumption (PSLEEP) shall be less than or equal to the maximum Sleep Mode power consumption requirement (PSLEEP_MAX) determined per Equation 4, subject to the following conditions:

  1. Only those interfaces that are present and available for use in the “as-shipped” product configuration may be considered functional adders.
  2. Product functionality offered through a DFE shall not be considered either a Primary or Secondary functional adder.
  3. Manufacturers may apply no more than three Primary functional adders to each product model, but may apply as many Secondary adders as present (with Primary adders in excess of three included as Secondary adders)

    Japan 100 Vac +/- 4.0 % 5.0 % 50 Hz/60 Hz +/- 1.0 %

  2. Low-voltage DC Input Power:
    1. Products may only be powered with a low-voltage DC source (e.g., via network or data connection) if the DC source is the only acceptable source of power for the product (e.g., no AC plug or EPS is included with the product).

    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 USB hub).

    3. Reported UUT power shall be equal to the AC power consumption of the low-voltage DC source with the UUT as the load, minus the AC power consumption of the low-voltage DC source with no load (PS), as measured per section A)6)5 of this procedure.

  3. Ambient Temperature: Ambient temperature shall be 23 oC ± 5 oC.

  4. Relative Humidity: Relative humidity shall be from 10% to 80%.

  5. Power Meter: Power meters shall possess the following attributes:

    • Minimum Frequency Response (Recommended): 3.0 kHz

    • Minimum Resolution:

      2. 0.1 W for measurement values from 10 W to 100 W;

      3. 1 W for measurement values from 100 W to 1.5 kW; and

      4. 10 W for measurement values greater than 1.5 kW.

      5. Measurements of accumulated energy should have resolutions which are generally consistent with these values when converted to average power. For accumulated energy measurements, the figure of merit for determining required accuracy is the maximum power value during the measurement period, not the average, since it is the maximum that determines the metering equipment and setup.

  6. Measurement Accuracy

    • Measurements made with these procedures shall in all cases have an accuracy of 5% or better, though manufacturers will usually achieve better than this. Test procedures may specify greater accuracy than 5% for some measurements. With knowledge of the power levels of current imaging products and the meters available, manufacturers can calculate the maximum error based on the reading and the range utilized for the reading.

    • For measurements of 0.50 W or less, the required accuracy is 0.02 W.

  7. Time Measurement: Time measurements may be performed with an ordinary stopwatch with resolution of at least one second.

  8. Paper Specifications:

    • Standard format products shall be tested in accordance withTable 16.

    • Large, small, and continuous format products shall be tested using any compatible paper size.

      Table 16: Paper Size and Weight Requirements

      Market Paper Size Basis Weight

5. Low-Voltage DC Source Measurement for All Products

  • Connect the DC source to the power meter and relevant AC supply as specified in Table 1.

  • Verify that the DC source is unloaded.

  • Allow the DC source to warm up for a minimum of 30 minutes.

  • Measure and record the unloaded DC source power (PS) according to IEC 62301 Ed. 1.0.

6.3 Configuration for Digital Duplicators

  1. Except as noted below, digital duplicators shall be configured and tested as printers, copiers, or MFDs, depending on their capabilities as shipped.

    1. Digital duplicators shall be tested at maximum claimed speed, which is also the speed that should be used to determine the job size for performing the test, not at the default speed as-shipped, if different.

    2. For digital duplicators, there shall be only one original image.

7. Pre-test UUT Initialization for All Products

  1. Prior to the start of testing, the UUT shall be initialized as follows:

    1. Set up the UUT per the instructions in the Manufacturer’s Instructions or documentation.

      1. Accessories such as paper source and finishing hardware that are intended to be installed or attached by the end-user shall be installed; however, their use in the test is at the manufacturer’s discretion (e.g., any paper source may be used).

    2. Connect the UUT to its power source.

    3. Power on the UUT and perform initial system configuration, as applicable. Verify that default delay times are configured according to product specifications and/or manufacturer recommendations.

      1. Product Speed for Testing: The product shall be tested with speed settings in their default as-shipped configuration.

      2. Auto-off for TEC Products: If a printer, digital duplicator or MFD with print-capability, or fax machine has an Auto-off capability and it is enabled as shipped, it shall be disabled prior to the test.

      3. Auto-off for OM Products: If a product has an Auto-off Mode enabled as shipped, it shall be enabled prior to performing the test.

    4. User-controllable anti-humidity features may be turned off or disabled for the duration of testing.

      1. Removed from the product; or

      2. Fully charged for at least 24 hours before beginning the test and left in place for the test.

8. Typical Electricity Consumption (TEC) Test Procedure

8.1 Job Structure

  1. Jobs per Day: The number of jobs per day (NJOBS) is specified inTable 18.

    Table 18: Number of Jobs per Day (NJOBS)

    Monochrome Product Speed, s (ipm) Jobs per Day (NJOBS)
    s = 8 8
    8 < s < 32 s
    s = 32 32

  2. Images per Job
    Except for fax machines, the number of images shall be computed according to Equation 6, below. For convenience, Table 22 at the end of this document provides the resultant images per job computation for each integer product speed up through 100 images per minute (ipm).

    Equation 6: Calculation of Number of Images per Job

    Calculation of Number of Images per Job

    Where:
    • NIMAGES is the number of images per job, rounded down (truncated) to the nearest integer,
    • s is the (monochrome) maximum reported speed in images per minute (ipm), calculated in section 6.1.A), of this test procedure, and
    • NJOBS is the number of jobs per day, as calculated perTable 18.

  3. Test Image: Test Pattern A from 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.

  4. Print Jobs: Print jobs for the test may be sent over non-network connections (e.g., USB), even on those units that are network-connected.

    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., PCL, Postscript), images shall be sent to the product in a PDL.

  5. 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 of required original images (e.g., due to limits on document feeder capacity). In this case, it is permissible to make multiple copies of each original, and the number of originals shall be greater than 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.

  6. Originals may be placed in the document feeder before the test begins.

    1. Products without a document feeder may make all images off of a single original placed on the platen.

8.2 Measurement Procedures

  1. Jobs per Day: Measurement of TEC shall be conducted according to Table 19 for printers, fax machines, digital duplicators with print capability, and MFDs with print capability, and Table 20 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 device to perform the specified print or copy jobs.

    2. Duplexing: Products shall be tested in simplex Mode. Originals for copying shall be simplex images.

    3. Service/Maintenance Modes: Service/maintenance modes (including color calibration) should generally not be included in TEC measurements.

      1. Any service/maintenance modes that occur during the test shall be noted.

      2. If a service/maintenance mode occurs during a job other than the first job, the results from the job with the service/maintenance mode may be replaced with results from a substitute job. In this case, the substitute job shall be inserted into the test procedure immediately following Job 4. The 15-minute job interval shall be maintained at all times.

    4. Accuracy: The specifications of the metering equipment and ranges used in each measurement shall be reported. Measurements must be conducted so as to result in a total potential error of the TEC value of no more than 5%. Accuracy does not need to be reported for cases where the potential error is below 5%. When the potential measurement error is close to 5%, manufacturers should take measures to confirm that it complies with the 5% limit.

    5. Energy Measurement Method: All measurements shall be recorded as accumulated energy over time, in watt-hours (Wh); all time shall be recorded in seconds or minutes.

      1. “Zero meter” references may be accomplished by recording the accumulated energy consumption at that time rather than literally zeroing the meter.

Notes:

  • Steps 4 and 10 –It may be unclear to independent testers which Sleep Mode is the final one and therefore a 4 hour time limit is provided.

9. Operational Mode (OM) Test Procedure

9.1 Measurement Procedures

  1. Measurement of OM power and delay times shall be conducted according toTable 21, subject to the following provisions:

    1. All power figures shall be recorded in watts (W) in accordance with IEC 62301, unless otherwise specified in this document.

    2. Accuracy: The accuracy requirement for this OM test procedure is 2% for all measurements except for Ready power, where it is 5%. The 2% figure is consistent with IEC 62301, although the IEC standard expresses it as a confidence level.

    3. Service/Maintenance Modes: Service/maintenance modes (including color calibration) generally should not be included in measurements. Any adaptation of the procedure needed to exclude such modes that occur during the test shall be noted.

Table 21: Operational Mode (OM) Test Procedure

Step Initial
State
Action(s) Record Unit of
Measure
1 Off Plug the unit into meter. Turn on unit. Wait until unit indicates it is in Ready Mode.  
2 Ready Print, copy, or scan a single image.  
3 Ready Measure Ready power. Ready power, PREADY Watts (W)
4 Ready Wait and measure default delay-time to Sleep. Sleep default-delay time, tSLEEP Minutes (min)
5 Sleep Measure Sleep power. Sleep power, PSLEEP Watts (W)
6 Sleep Wait and measure default delay time to Auto-off. (Disregard if no Auto-off Mode) Auto-off default-delay time Minutes (min)
7 Auto-off Measure Auto-off power. (Disregard if no Auto-off Mode) Auto-off power PAUTO-OFF Watts (W)
8 Auto-off Manually turn device off and wait until unit is off. (If no manual on-off switch, note and wait for lowest-power Sleep state).
9 Off Measure Off power. (If no manual on-off switch, note and measure Sleep Mode power). Off power POFF Watts (W)

Notes:

  • Step 1 – If the unit has no Ready indicator, use the time at which the power consumption level stabilizes to the Ready level, and note this detail when reporting the product test data.

  • 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 this 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 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 45minute default-delay time to the second level.

10. Test Procedures for Products with a Digital Front End (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.

  1. If the DFE has a separate mains power cord, regardless of whether the cord and controller are internal or external to the imaging product, a five-minute energy measurement of the DFE alone shall be made while the main product is in Ready mode. The unit must be connected to a network if network-capable as shipped.

  2. If the DFE does not have a separate mains power cord, the manufacturer shall document the AC power required for the DFE when the unit as a whole is in a Ready mode. This will most commonly be accomplished by taking an instantaneous power measurement of the DC input to the DFE and increasing this power level to account for losses in the power supply.
