EPA background information
Under the current Presidential Administration's direction, the Environmental Protection Agency (EPA) has
defined a set of maximum power usages for laser printers and other computer products. The EPA estimates that if
all desktop personal computers and peripherals entered a low-power mode when not in use, the overall savings in
electricity could amount to over one billion dollars each year. It could also prevent the emission of 20 million tons
of carbon dioxide (the equivalent output of 5 million cars). NOTE: The Environmental Protection Agency, as a
matter of policy, does not endorse any particular company or its products.

EPA compliancy guidelines
In order to be Energy Star Compliant, printers must meet the following guidelines established by the EPA:

    Printer speed/max. power               Default time to LPS*                     LPS max. power

1-7 ppm                             14 Minutes                           30 W
8-14 ppm                            30 Minutes                           30 W

>15 ppm/Color                       60 Minutes                           45 W
*LPS = Low Power State

HP LaserJet 4100 series printers
The HP LaserJet 4100 series printer is designed to reduce energy consumption. Energy usage drops significantly
while in low-power (PowerSave) mode (see the table below). Not only does this save natural resources, but it also
saves money without affecting the high performance of this printer. This product qualifies for Energy Star
compliance.

HP LaserJet 4000 series printers
The HP LaserJet 4000 series printers are designed to conserve electricity by dropping from 330 W while printing
to 16 W when in the Power Save Mode. For maximum energy conservation, Hewlett-Packard recommends that
the printer be turned off when it will not be used for more than a few hours. With this power-saving design, all
models of the printer qualify for the U.S. Environmental Protection Agency’s Energy Star Computers compliance.

HP LaserJet 5 and 5MP printers
The HP LaserJet 5P and 5MP printers are designed to conserve electricity by dropping from 165 W while printing
to 5 W when in the Power Save Mode. The instant-power-save/instant-on capability of these printers makes a
standby mode unnecessary. For maximum energy conservation, Hewlett-Packard recommends that the printer be
turned off when it will not be used for more than a few hours. With this power-saving design, both models of the
printer qualify for the U.S. Environmental Protection Agency’s Energy Star Computers compliance.

HP LaserJet 5Si and 5SiMX printers
The HP LaserJet 5Si and 5SiMX printers are designed to conserve electricity by dropping from 500 W while
printing to 21 W when in the Power Save Mode. For maximum energy conservation, Hewlett-Packard
recommends that the printer be turned off when it will not be used for more than a few hours. With this power-
saving design, both models of the printer qualify for the U.S. Environmental Protection Agency’s Energy Star
Computers compliance.

HP LaserJet 5si Mopier
The HP LaserJet 5Si Mopier is designed to conserve electricity by dropping from 550 W while printing to 43 W
when in the Power Save Mode. For maximum energy conservation, Hewlett-Packard recommends that the printer
be turned off when it will not be used for more than a few hours. With this power-saving design, the mopier
qualifies for the U.S. Environmental Protection Agency’s Energy Star Computers compliance.

HP LaserJet 4L and 4ML printers
The HP LaserJet 4L and 4ML printers are designed to conserve electricity by dropping from 180 W to less than 5
W when they go into Intelligent Off or standby mode. With this new, power-saving design, these printers qualify
for the U.S. Environmental Protection Agency's Energy Star Computers award.

HP LaserJet 4p and 4mp printers
The HP LaserJet 4P and 4MP printers are designed to conserve electricity by dropping from 180 W to less than 15
W when they go into standby mode. With this new, power-saving design, these printers qualify for the U.S.
Environmental Protection Agency's Energy Star Computers award.

HP LaserJet 4Si and 4Si MX printers
Newly manufactured HP LaserJet 4Si and 4Si MX printers are Energy Star compliant as of January 3, 1994.
Energy Star compliant HP LaserJet 4Si and 4Si MX printers are designed to conserve electricity by dropping from
1100 W while printing, to 240 W when in standby mode, then to less than 45 W in Power Save mode.

HP LaserJet 4 Plus and 4m plus printers
The HP LaserJet 4 Plus printer is designed to conserve electricity by dropping from 300 W while printing, to 80
W when in standby mode, then to 22 W in Power Save mode. The HP LaserJet 4M Plus printer is designed to
conserve electricity by dropping form 300 W while printing, to 80 W when in standby mode, then to 28.5 W in
Power Save mode. With this new, power-saving design, both models of this printer qualify for the U.S.
Environmental Protection Agency's Energy Star Computers award.

HP LaserJet 4V and 4mV printers
The HP LaserJet 4V printer is designed to conserve electricity by dropping from 380 W while printing, to 110 W
when in standby mode, then to 28 W in Power Save mode. The HP LaserJet 4MV printer is designed to conserve
electricity by dropping from 385 W while printing, to 115 W when in standby mode, then to 31 W in Power Save
mode. With this new, power-saving design, both models of this printer qualify for the U.S. Environmental
Protection Agency's Energy Star Computers award.

HP LaserJet 4 and 4m printers
The HP LaserJet 4 and 4M printers are not Energy Star compliant. There is not an upgrade to make them Energy
Star compliant.

HP Color LaserJet printer
The HP Color LaserJet printer is designed to conserve electricity by dropping from 520 W while printing, to 135
W when in standby mode, then to 40 W while in PowerSave mode. The power save mode default is 60 minutes,
which can be changed from the control panel. With this new, power-saving design, these printers qualify for the
U.S. Environmental Protection Agency's Energy Star Computers award.

HP Color LaserJet 2500 printers
The HP Color LaserJet 2500 printer is designed to conserve electricity by dropping from 400 W while printing
color or 224 W while printing monochrome to 30 W when in standby mode. This unit does not have a “power
save” mode and instead relies on standby mode for power conservation. With this power-saving design, these
printers qualify for the U.S. Environmental Protection Agency’s Energy Star Computers award.
