COPIER PRODUCTIVITY
Advertised speeds are always quoted using the simplest
route—in-and-out of a device. Of course, users often apply
finishing options, incorporate different media sizes and
types into the document, print in duplex, and add other
elements that can affect speed. In the chart below, BERTL
tests how different modes—mixed-size original mode and
duplex mode—affect document-feeder productivity.
In order to assess copier productivity, BERTL ran a series
of copy jobs in order to determine document-feeder
scanning speed, the affect of the first set out on overall
engine speed, and whether specific job attributes affect
engine throughput capability. Each job was set up by
feeding media from the shortest media route to the shortest
available output destination. A separate test examines
how adding finishing/output destinations affects
productivity.
