ITB Contact and Release
To prevent early deterioration of the color photosensitive drum, the Image transfer belt unit is provided with a contact/separation mechanism and, during monochrome printing, separation of the image transfer belt from the color photosensitive drum is controlled. Contact/separation of the image transfer belt unit is performed via a gear from an ITB contact and release motor (also used as a magenta toner supply motor). Separation or contact is detected by the ITB contact and release sensor.

Image Transfer Flow
By arranging the imaging sequence in the order Y > M > C > Bk, cyan is laid on top of magenta, which increases tolerance to image blurring and image reddening when dark blue is output, and improves image quality.
