Duplex
A mechanism that will automatically turn over a sheet of paper so that the
machine can print (or scan) on both sides of the paper. A printer equipped with
a Duplex Unit can print on both sides of paper during one print cycle.
Duty Cycle
Duty cycle is the page quantity which does not affect printer performance for a
month. Generally the printer has the lifespan limitation such as pages per year.
The lifespan means the average capacity of print-outs, usually within the
warranty period. For example, if the duty cycle is 48,000 pages per month
assuming 20 working days, a printer limits 2,400 pages a day.
