Dell C1765NF MFP Laser Printer - Handbuch (Seite 11)

User Information Per Blue Angel Mark Requirements of RAL-UZ171
Energy consumption of the device
The standard usage cycle according to Energy Star version 1.1 assumes the
following for a device such as Dell C1765nf/C1765nfw Color Multifunction
Printer: 15 copy jobs with 7 pages each working day, simplex at monochrome
printing, i.e 105 pages/day.
This results in an electric power consumption of 0.99 kWh for one week (7-
day week with 5 working days with 8 hours each) in standard usage cycle
according to Energy Star version 1.1 determined with a test pattern according
to ISO 24735.
The value was measured with the above mentioned settings (delivery status).
Regarding the electric power saving modes you can partly change their
activation times. If you shorten an activation time the device will faster
switch over to an electric power saving mode and you will save electricity
costs. If you, however, want to extend an activation time, please consider: The
device will then switch down later or not at all. Thus, it will stay longer in a
mode of increased power consumption and, hence, consumes more electric
power. Then, in addition, it might no longer meet the maximum value for
electric power consumption of the Blue Angel. We recommend not extending
the activation times.
Noise emission
The declared A-weighted sound power level (L
WAd
) of the printer in
monochrome mode is at an operating speed of 15 pages/minute 62.1 dB(A).
The declared A-weighted sound power level (L
WAd
) of the printer in color
mode is at an operating speed of 12 pages/minute 59.6 dB(A).
Office equipment with a sound power level L
WAd
> 63 dB is not suitable for
use in rooms predominantly used for intellectual activities. Because of their
high noise emission they shall be placed in separate rooms.
