    Using -300 and -600 V results in a more accurate calibration of the sensor, since the voltage applied to the supply board is much closer to the actual value, which is –450 V for V (Development bias) during the process control self check. A172/A199...

  • Page 55: Gradation Pattern Detection

    A latent image of a 14-grade gradation pattern is created for each color (Bk, C, M, Y) by changing the LD input current. By creating 14 grades, the machine can achieve a more precise development gamma factor, resulting in a more reliable pointer control. A172/A199...

  • Page 57: Forced Toner Consumption Mechanism

    When the machine detects V determines that the amount of toner in the development unit is low. At this moment, the copy job is interrupted, and toner is fed into the development unit forcibly. After forced supply, the machine resumes the copy job. A172/A199...

  • Page 58: Drum Unit

    The life time of the drum is increased due to the decrease in the amount of corosive gas. • Uneven charge problems are alleviated due to the increase of the amount of current per meter of the corona wire. A172/A199...

    As shown above, one cycle of this agitation consists of rotating in both directions, and is performed for five consecutive cycles. In order to prevent unnecessary toner from entering the development unit during agitation, the transport screw gear [B] has some play before rotation is transmitted to the transport screw.
