PPM control

• PPM control is provided to prevent the temperature on edges of the heating roller from
increasing during a multi-print cycle using plain media of a small size.
• The distance between sheets of media is widened according to the number of printed
pages set to be produced and the media length. This evens out the temperature of the
heating roller and thus stabilizes fusing performance of the printed toner image.
• The PPM control is provided at 20 ppm for a multi-print cycle of producing 20 pages. The
number of printed pages per minute is established as detailed below for each media size
for the 21st and subsequent pages.
• No PPM control is provided for a multi-print cycle of color printing, as it is 1/4 of the
monochrome printing.
