Aspects of the disclosure can provide a sensor system. The sensor system can include a belt having an undesirable portion and an aperture formed at a distance from the undesirable portion, a reflector located in the aperture, and a detector that senses a light reflected by the reflector to determine a location of the undesirable portion.

Method and apparatus for sensing locations on a belt

An apparatus and printing machine that contain a cleaner brush with long sweeper fibers orientated along the overall width of the brush, and having a greater length than the majority of fibers of the brush to remove the particles that adhere to the cleaner housing and thus, prevent toner droppings.

Cleaning brush having fibers of different lengths

A method, apparatus and printing machine are disclosed that contain a monitoring system that includes a sensor and artificial stress conditions to determine the cleaner brush life. A comparative analysis is performed from the data provided by the monitoring system of a normal cleaning residual toner particle mass and artificial stress conditions cleaning residual toner particle mass to predict brush cleaner life reliably.
