Abstract
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.
Claims21
A printing apparatus to deposit heated phase change ink on recording media comprising:
- a printhead having an inlet for receiving heated phase change ink from a source of ink;
- a heated conduit having a first end and a second end, the first end of the heated conduit being operatively connected to the inlet of the printhead and the second end being operatively connected to the source of ink to carry heated phase change ink from the source of ink to the printhead;
- a housing to which the printhead is mounted and through which at least a portion of the heated conduit passes;
- a temperature sensing device configured to sense a change in temperature in response to a leaked heated phase change ink contacting the temperature sensing device, the temperature sensing device positioned at a location in the housing where gravity can direct the leaked heated phase change ink into contact with the temperature sensing device;
- and
- an annunciator operatively connected to the temperature sensing device and being configured to activate in response to the leaked heated phase change ink contacting the temperature sensing device.
