Time to first print
All first copy times are measured for 600 image quality, simplex printing on letter-size paper. The test job
consists of the character “A” followed by a form feed (single-page job). The first copy time is defined as the
elapsed time from pressing
Enter on the keyboard to the page exiting to the output bin. All tests pick paper from
the primary input tray and the page exits into the primary output bin.
Standby times may be longer if the toner control senses that toner flow needs to be checked or adjusted.
