This machine performs the throughput down control that extends the paper interval and lower the printing speed to prevent the edge of the fixing heater from over-
heating at continuous printing of small paper (the paper with narrow width) and to prevent the fixing heater unit from overheating at high-volume continuous print-
ing.
An extended paper interval lowers the fixing heater temperature between the papers, preventing the edge of the roller of fixing assembly and the delivery unit from
overheating.
This control has the following 3 modes and the operation sequence differs depending on each modes.
Mode 1: sequence (For prevention of temperature increase in the edge)
Condition: paper length is 264 mm or shorter
Operation: print speed drops according to the setting item (paper type) on the printer driver

Mode 2: sequence (For prevention of temperature increase in the edge)
Condition: paper length is 264 mm or longer while paper width is 190 mm or shorter
Operation: print speed drops to 3 ppm from the 2nd sheet of continuous print
Mode 3: sequence (For prevention of temperature increase in the delivery unit)
Condition: paper width is 190 mm or longer
Operation: print speed drops to 6 ppm from the 251st sheet of continuous
