Division (iii) Additional Measurement for Products with a Digital Front End (DFE)

This step applies only to products that have a DFE as defined in section A.32.

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 is to be made while the main product is in Ready mode. The unit must be connected to a network if network-capable as shipped.

If the DFE does not have a separate mains power cord, the manufacturer must 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.
