An apparatus for providing a jittered clock signal has a reverse-biased diode. The method comprises the steps of: a first scanning for drawing in a plurality of first areas along a scanning direction; and a second scanning for drawing in a second area between the plurality of first areas drawn in by the first scanning. The carriage can be aligned with any one of the hoppers such that the lift mechanism will elevate the refuse bin and invert it over the hopper container. A movable cover is fast with the actuator arm and defines an ink outlet. The power generated by said charging component, is then transmitted to said battery via a voltage regulating device.
