摘要：
Methods and systems to monitor the operation of ink jet print heads that are easy to implement and inexpensive are provided. The print head is positioned over an array of wires. The array of wires is heated, and the print head is controlled to eject droplets of ink from each nozzle of the print head onto a corresponding wire. Nozzles that are operating properly will eject droplets of ink, which will lower the temperature of the wire, thereby causing a change in resistance of the wire. Nozzles that are not operating properly will not eject droplets of ink, and therefore the resistance of the corresponding wires will remain constant. The resistance of each wire is monitored, and if a change in resistance in a wire is not detected, indicating that the ink droplets were not ejected onto that wire, a signal is generated that indicates a non-operational nozzle.
