*1: The first-copy time is measured after the power save indicator turns off following power on, using the document glass with the polygon
rotating in the copy ready state and "Selection of copy start state" set to ON in the user programs (A4 (8-1/2" x 11"), paper fed from
paper tray).
The first-copy time may vary depending on machine operating conditions and ambient conditions such as temperature.
