A capacitive sensor for sensing amount of waste toner in a waste toner box of an imaging apparatus includes a capacitor that has a pair of separated plates disposed within the interior of the waste toner box. The capacitance of the capacitor changes with the amount of toner in between the plates of the capacitor. A sensor circuitry is connected to the plates of the waste toner box that measure the capacitance of the capacitor as a voltage value. This voltage value is provided to a controller that determines a relative change in the capacitance value by determining a change in capacitance of the capacitor with respect to a number of pages printed by the imaging apparatus. The controller then determines the state of the waste toner box based on this relative change in capacitance.

An apparatus for the management of the fluid level in a media coating system. In one embodiment, the apparatus has a supply item for the storage of a media coating fluid and an applicator having a trough for receiving the media coating fluid from the supply item. The apparatus utilizes a fluid level detection sensor that is located within the applicator to measure whether the media coating fluid level within the trough of the applicator is either above or below a threshold position and to generates an output signal. The apparatus has a controller for receiving the output signal and controlling delivery of the media coating fluid from the supply item to the applicator.

A coating apparatus for applying a coating liquid to a printing substrate. The coating apparatus has a rotatable first roll and a rotatable second roll, each having a surface energy. The second roll is positioned adjacent to the first roll and defines with the first roll a first nip through which the printing substrate passes A metering device is provided for applying a substantially uniform layer of coating liquid onto the second roll. The second roll in turn transfers the coating liquid to the printing substrate. The surface energy of the second roll is greater than the surface energy of the coating liquid. In one embodiment, the metering device includes a rotatable third roll and a doctor blade contacting the third roll, each having a surface energy. The surface energy of at least a portion of either or both the third roll and doctor blade is less than the surface energy of the coating liquid.

A low-profile keyboard (5) each switch (3) having a dished keybutton (3) held upward by a rubber dome (49) and having ribs (55) which depress extension (43 and 31) which carry electrical traces (45 and 33) to activate the switch. The assembly is mounted on post (15). A lower recess (21) permits excess travel to a quiet stop. The rubber sheet (47) provides spill resistance.
