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.
This control extends the interval between heater on and prevents 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 264mm or shorter
Operation: print speed drops according to the setting item (paper type) on the printer driver. Simultaneously, control the target temperature of the fixing assembly
according to the temperature in the following table.
F-2-50
T-2-12
Mode 2: sequence (For prevention of temperature increase in the edge)
Condition: paper length is 264mm or longer while paper width is 190mm or shorter
Operation: print speed drops to 3ppm from the 2nd sheet of continuous print. Simultaneously, control the target temperature of the fixing assembly within the
range of approx. 155 deg C to 170 deg C.
Mode 3: sequence (For prevention of temperature increase in the delivery unit)
Condition: paper width is 190mm or longer
Operation: print speed drops to 5ppm from the 251st sheet of continuous. Simultaneously, control the target temperature of the fixing assembly within the range
of approx. 132 deg C to 134 deg C.
