The thermistor contacting the center of the hot roller surface monitors the temperature of the hot roller. The
CPU turns the fusing lamps on and off to keep the hot roller surface at the target temperature. The target
temperature depends on the paper type.
Paper Temperatures Adjust With
Normal 195°C±5 (383°F±9 SP1105-001, 002, 007, 008
OHP 165°C (329°F) SP1105-003, 004
Thick Paper 200°C (392°F) SP1105-005, 006
SP1105: See the SP table in Section 5 for details.
As shown in the illustration, at power on when the temperature is less than 100°C, there is an interval of
70 s during which the hot roller rotates before printing starts (this is called ‘fusing idling’). This interval
allows the hot roller to reach the control temperature. At power on when the temperature is over 100°C,
printing can start as soon as the hot roller reaches the warm-up temperature of 182°C.
• SP1106 (Fusing Temperature Display) displays the current center and end temperatures for the hot
roller.
