Konica Minolta bizhub 4000i

At 42 pages a minute, the bizhub 4000i is faster than 123 of the 305 office printers certified, and 157 are faster.

Its certified typical electricity use of 28.6 kWh a year is 16% above the median of 66 monochrome office printers within 20% of its speed (24.7 kWh). Electricity is a small part of what a printer costs to run; toner or ink per page is usually the larger one.
