3. Copy performance
*1: The first-copy time is measured after the power save indicator turns off following power on, using the document glass with the polygon rotat-
ing 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.
