Uses 3.5 KW of power when busy and 65 watts on
standby.
Daily power consumption = (3500 watts x 5
hours) + (65 watts x 19 hours)
=17 500 + 1235
=18 735 watts per day
= An Average of 780.625 watts per hour
= 0.78 KWH
A coal fired power-station creates close to 1 KG of
CO2 for every KWH of energy produced, so in order to
offset one day of photocopier energy it would take 0.78
units x 24 hours or 18.7 Kg in carbon offsets
To calculate the annual carbon footprint of the
device we could multiply the daily figure by 250,
assuming the machine is switched off over holidays and
weekends.
This gives us a figure of 4675Kg or 4.675 tonnes of
CO2 per year.
The figures are naturally subject to variables such as
make and model of machine, usage, and power source
