Fusing Roller Pressure Release - MINOLTA-QMS Magicolor 2200 Series Manual

6-5 Fusing roller pressure release

A pressure release operation is performed at the fusing contact motor (M5) as needed to extend the life of the pressure
roller for fusing.
Contact
• The fusing pressure motor is set on, and the pressure gears turn (forward). The blade-shaped gear is turned and the
pressure roller is made to contact the fusing roller.
• The fusing pressure position detecting sensor (PC10) is set on and the contact of the pressure roller is detected.
• The fusing pressure motor is set off.
Release
• The fusing pressure motor is turned on in reverse. This reverses the pressure gear and releases the pressure roller.
• At the pressure release sensor the release of the pressure roller is detected by the pulse disk plate attached to the same
shaft as the pressure gear, and release is made to the specified distance.
• The fusing pressure motor is turned off.
That release is also made during the envelope printing mode to reduce wrinkles.
