Method and apparatus to control waste toner collection in an image forming apparatus |
摘要 |
An image forming apparatus includes a waste toner system that collects waste toner in a waste toner container. An amount of waste toner collected in the container is increased by using a motor-driven toner distributing member that distributes accumulated toner within the container. The waste toner system may detect the accumulation of waste toner by monitoring a motor control circuit while the toner distributing member is being driven. For example, the system may detect excess accumulation by comparing the monitored values of a speed control signal with one or more reference values corresponding to nominal accumulation conditions. Whether or not the motor is speed controlled, the apparatus may use a shared motor that drives one or more image forming process members and the toner distributing member. A drive arrangement may be used to selectively drive the toner distributing member based on motor direction to avoid interfering with image forming operations.
