Image Transfer Roller Pressure Contact And Release Spacing - MINOLTA-QMS Magicolor 2200 Series Manual

5-5 Image transfer roller pressure contact and release spacing

The image transfer roller applies and releases pressure to the image transfer as needed.
• When the toner image is transferred to the paper, the image transfer roller pressure contact solenoid (SL7) is set on and
the drive force is conveyed to the cam, forcing it to turn, and the image transfer roller applies pressure to the image
transfer belt. Refer to the drawing below left.
• Once the toner image has been transferred to the paper, the image transfer roller pressure solenoid is set on, and the
cam rotates and pushes the lever that releases the image transfer roller from the image transfer belt. Refer to the draw-
ing below right.
• The shield plate attached to the cam blocks the image transfer roller pressure sensor to detect image transfer roller
pressure.
