*The print speed may vary according to conditions, such as paper size and paper tray.
NOTE:
• When a smaller size paper than A4 or Letter is printed, the temperature on both edges of
the fixing unit is much higher than the temperature on the center of the unit where the paper
is fed depending on the setting or model. Therefore, the print speed is slowed in order to
decrease the temperature on the edges after the specified time, it is maximum print speed
when you first start printing.
• Max. speed is 16/17 ppm or more. It varies depending on the paper size.
