A printing apparatus includes a printhead module having an ink leakage detector to detect a leaked phase change ink. The ink leakage detector includes a plurality of resistance temperature detectors or resistive thermal devices to detect the leaked phase change ink. A horizontally mounted overdriven thermistor can also be used to detect leaked ink.

System for detecting leakage of phase change inks

This is a waste cyclone toner dispense system with a controlled gate and a collection bag below the gate. The controlled gate is configured to be opened and closed at a predetermined time thereby permitting the use of relatively inexpensive bags for collection of toner debris. The gate is hinged to permit easy opening by a controller and motor. The controller turns off any pressure while the gate is open. The drop gate conveys when open waste toner from an upper waste collection funnel to the collection bag.

Waste cyclone dispense system with a controlled gate

This is a waste cyclone toner dispense system with a controlled gate and a collection bag below the gate. The controlled gate prevents pressure from entering the bag thereby permitting the use of relatively inexpensive bags for collection of toner debris. The gate has rotating blades tightly pushed against a sealing wall, such as rubber or the like. The wall must prevent pressure from reaching the bag and remaining only above the bag. The rotating blades convey waste toner from an upper collection to the collection bag.

An exterior or interior structural member in the form of a panel for an image forming or similar device is disclosed which has an integral plenum passage for fluid/air. The panel may be thermoformed and/or have mechanically connected parts, and may include other elements, such as toner bottle covers.
