A sticker assembly is disclosed and includes an indicia-bearing sticker having an adhesive layer. The dynamic data is refreshed at a second refresh rate when the control signal is deasserted for a predetermined duration. Alternatively, the controller controls so that rotational speed of the output shaft of the gear assembly is adjusted to at around the lowest rotational speed within a range of rotational speed, the range being determined so as to include a rated power region as an upper operational limit. The second gain may simply correspond to the first gain increased by a certain dB value. A rotating actuator displaces the toner moving device from the first position to the second position to move the toner in the housing away from the inlet.
