• The main body leaves the power save mode.
• A door is closed.
(2) Control termination timing
• The Fusing roller reaches a predetermined temperature.
• A door is opened.
B. Wait control
• Control is provided to ensure that the temperature of the fusing roller becomes a con-
stant value during the standby state.
(1) Control start timing
• At the end of the warm-up control
• At the end of a print cycle
(2) Control termination timing
• At the start of a print cycle
• A door is opened.
• A malfunction or media misfeed occurs.
C. Print control
• The fusing speed and fusing temperature are controlled to ensure a sufficient fusing
strength.
(1) Control start timing
• A print request is received.
(2) Control termination timing
• A malfunction or media misfeed occurs.
(3) Print control temperatures
• The fusing roller temperature is set according to the type of media, main body interior
temperature (as measured by the temperature/humidity sensor), and warm-up start tem-
perature.
• For types of media other than plain paper, the fusing speed is controlled at the 1/2
speed.
(4) Print control temperature adjustments
• The temperature during print control is adjusted using the menu available from the con-
trol panel. The temperature can, however, be decreased only.
