Print temperature control
To set optimal target temperature to prevent fixing failure or offset, and keep the specified
target temperature during printing
A.Setting target temperature
Target temperature is specified depending on the paper type, paper size, elapsed time
since the last control (including the standby control) of fixing temperature and fixing
temperature at the start of warm-up control.
B.Temperature control during printing
When the paper passes in the fixing unit, the fixing temperature is controlled to keep
the target value (see the table on the next page) according to the detection result of
main thermistor.
C.Sheet-to-sheet distance temperature control
To prevent the excessive temperature rise and to save the power consumption, the
target temperature is set 5 deg C low (in case of plain paper *1) from the printing
temperature.
*1. When the fixing mode is the plain paper 1, plain paper 2 or thin paper, set to -5 dec C. In the other cases, set to -15 or -20 deg C low or +5 deg C high according paper type
Target temperature during printing
The control temperature is determined according to the fixing mode and to the fixing temperature at the start of warm-up control. The following 16 modes are provided as the fixing mode. The fixing modes are changed by the paper setting and the service mode setting.
The following table is the control temperature when the fixing temperature is less than 55 deg C at the start of warm-up control.
