A toner container according to one example embodiment includes a housing having a reservoir for holding toner. A rotatable shaft is positioned in the reservoir and has a rotational axis. A toner agitator is rotatably coupled to the rotatable shaft. A first electrical conductor and a second electrical conductor are positioned on the housing. The first electrical conductor and the second electrical conductor form a capacitor having a capacitance that changes in response to a change in an amount of toner in the reservoir between the first electrical conductor and the second electrical conductor. The first electrical conductor includes a rod positioned in the reservoir at the rotational axis of the rotatable shaft and extending along the rotational axis of the rotatable shaft.

Capacitive toner level sensor

An apparatus includes a mid-frame for supporting a back side of a sheet of media. A carrier system is configured to transport a carriage in a reciprocating manner with respect to the mid-frame. The carriage includes a bay. A perforation cartridge is configured to be received in the bay. The perforation cartridge contains a perforation forming mechanism. A controller is coupled to the perforation forming mechanism, the controller being configured to select at least one of a vertical perforation resolution and a horizontal perforation resolution of the apparatus.

Perforation forming mechanism for use in an imaging apparatus

An apparatus for perforating a sheet of print media having a front side and a back side includes a printhead carriage for carrying a printhead. A perforator carriage carries a perforation forming mechanism. An isolation damper having elastic, vibration absorbing, characteristics couples the printhead carriage to the perforator carriage.

Base portion for ink refill tank

Ink refill tank

An assembly for refilling a printer cartridge includes a base that receives the printer cartridge to be refilled. A lid is located on the base and includes separate stations that sequentially open a refill opening, provide a predetermined amount of air to an equalize opening of the cartridge, dispense ink through the refill opening into the cartridge, and seal the refill opening. In a preferred embodiment, the four stations are mounted on the lid that is rotatable about an axis. The lid forms a seal with the printer cartridge so that air flow to an internal chamber of the cartridge is controlled during the refill process. The base contains any spills, mess, or the like, overcoming the types of problems associated with other ink refill processes and provides an accurate, dependable refill of ink to the printer cartridge.
