  • FAN BYPASS SYSTEM FOR CONTAMINATION CONTROL
    Publication number: 20160266541
    Abstract: A contamination control apparatus for controlling contamination in an image forming device is provided. The apparatus includes an air mover located in the image forming device; a first duct, a first end of the first duct receiving non-contaminated air, and a second end of the first duct being fluidly connected to an air input of the air mover such that the air input receives the non-contaminated air from the first duct; an exhaust duct, a first end of the exhaust duct being fluidly connected to an air output of the air mover such that the exhaust duct receives the non-contaminated air from the air output; and a second duct, a first end of the second duct being positioned such that contaminated air is drawn into the second duct, and a second end of the second duct being fluidly connected to the exhaust duct at a position downstream of the air output of the air mover and upstream of the second end of the exhaust duct.
