Abstract
An electrophotographic printer includes a rotatable member and a carriage rotatable around an axis. Two rotatable chargers are mounted on the carriage, each for charging the rotatable member. A carriage drive rotates the carriage to bring the first charger into contact with the rotatable member and the second charger into operative arrangement with a cleaner, or vice versa. A charger drive rotates the charger in operative arrangement with the cleaner at a speed greater than a selected speed or with a torque greater than a selected torque, and the rotatable member rotates the rotatable charger in contact therewith at the selected speed with the selected torque.
