Woo! Welcome Lexmark, to the 21st century.
If you’re running a large workgroup, you need a printer that is fast, cheap to run and has enough flexibility to handle a variety of media and to grow with the tasks it’s asked to perform. Endeavouring to address all these needs, while also offering colour, duplex and walk-up direct print, is Lexmark’s C736dn. Lexmark C736dn …
This printer is is Energy Star compliant which is good!
Lexmark gives an Energy Star Typical Electricity Consumption (TEC) of 4.69kWh (units) per week. At a typical UK price of 12p per unit this gives an electricity cost of about £29 per year.
As I understand it, for a printer of this speed (35ppm), the TEC is based on printing over 18,000 monochrome pages per month. This is on the high side because Lexmark specifies a recommended page volume of 2500 to 10000 per month. Even if colour printing uses more electricity, consumption should in practice remain below £29. Many many would consider to be negligible when compared with the capital, paper and consumables costs.
I am unable to give cost for plugging it into the mains, because Lexmark do not specify standby power consumption.
