Composition/Operation
17.3.4 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 paper of a small size.
• The distance between sheets of paper is widened according to the number of printed
pages set to be produced and the paper length. This evens out the temperature of the
heating roller and thus stabilizes fusing performance of the printed toner image.
• To perform the PPM control, the number of printed pages per minute is established for
each paper size.
