Turning the power ON
→ The IH coil is turned ON.
→ The set number "1" reproduction ratio "100%" and "WAIT WARMING UP" appears.
→ The fan motors are turned ON.
→ Initialization of the scanning system
- The carriage moves to the home position and stops.
- The carriage moves to the peak detection position.
- The exposure lamp (EXP) is turned ON.
- Peak detection (a white color is detected by the shading correction plate)
- The exposure lamp (EXP) is turned OFF.
- The carriage moves to the home position.
→ Initialization of the feeding system

- The fuser roller rotates.
→ The drum motor (M11) is turned ON.
- The drum rotates.
→ The used toner transport motor (M9) is turned ON
- The used toner transport auger rotates.
→ Image quality control
- It charges the drum and detects the drum surface potential to set the optimal condition for
outputting the image.
- It forms a patch on the drum and reads out its reflective ratio to set the optimal condition.
3. When the surface temperature of the fuser roller becomes sufficient for fusing;
→ The IH coil (IH-COIL) is turned OFF.
→ The set number "1" and "READY" are displayed.
Copier operation
