CROSS-NOZZLE ABNORMALITY DETECTION IN DROP DETECTOR SIGNALS
In an example, a print apparatus includes a printhead carriage to receive a printhead comprising a print agent ejection nozzle, a drop detector to acquire a signal indicative of variations in a parameter detected by the drop detector over a period of drop detection; a memory to store nozzle location...

Summary: | In an example, a print apparatus includes a printhead carriage to receive a printhead comprising a print agent ejection nozzle, a drop detector to acquire a signal indicative of variations in a parameter detected by the drop detector over a period of drop detection; a memory to store nozzle location information of the nozzles; and processing circuitry comprising a correlation module to correlate the drop detector signal with the nozzle location information wherein the processing circuitry comprises an abnormality detection module to determine, based on an output of the correlation module, a cross-nozzle abnormality that affects a subset of nozzles. |
