7. Detailed Descriptions
• Between Standby and Paper Feed
In standby mode, the fusing temperature is maintained at t4 (SP1-105-012).
If the operation panel or ARDF is operated during standby, the fusing temperature is maintained at
t3 and kept at t3 until paper feed starts.
At the beginning of paper feed, additional heat is applied and the temperature is higher than the
specified fusing temperature (t1) which differs depending on paper thickness.
The temperature is gradually lowered until it reaches the specified fusing temperature (t1).
The additional heat applied differs according to the difference between the temperatures of fusing
thermistor (center) and fusing thermistor (end) measured at the beginning of paper feed.
When the difference is 25 °C or more: 35 °C is added.
