G. Print start wait control
• To ensure good fusing performance for the first print, the print start timing is retarded.
• The control also prevents the media from sticking during printing on OHP film in the color
mode.
•
The print start timing is retarded using the value of either one of the two wait periods,
whichever is longer, calculated under the following two conditions.
1. Using the data provided by the Temperature/Humidity Sensor (HS1) and other sensors,
the period of time that begins when the print control (print start timing control) is started
and ends when the first sheet of media reaches the Fusing Belt is calculated.
2. If the first print is produced on OHP film in the color mode, the wait time is calculated to
ensure that the media interval is the specified value.
16.3.3 Fusing temperature control
• To fuse the toner image on the media (image yet to be permanently fixed) properly into
the media, the Heater Lamps are turned ON and OFF as necessary to bring the fusing
temperature to an appropriate level.
• Thermistors are used to detect the surface temperatures of the Heating Roller and Fus-
ing Pressure Roller. The Heater Lamps are then turned ON and OFF as necessary to
achieve the set temperature.
• The control temperature in the print command wait state is called the standby tempera-
ture, while that for permanently fix the toner image on media into the media is called the
print temperature.
