Summary:Systems and methods are described that facilitate replacing cleaning blades employed to chisel excess toner from a photoreceptor surface. For example, a cleaning unit can comprise a blade holder with a plurality of cleaning blades attached thereto, which is rotated (e.g., by an actuator) to remove a used cleaning blade from the photoreceptor surface and position a new cleaning blade against the photoreceptor surface. Blade replacement can be triggered by a detected defect on an output image or by detected excess toner on the photoreceptor surface downstream from the cleaning blade. Additionally, blade replacement can be triggered as a function of blade use (e.g., measured in time, prints, photoreceptor cycles), friction force on the blade, or a combination thereof, to achieve a desired (e.g., low) cleaning unit failure probability.
