Potential printhead strike determination

A method comprising:

• accessing, by a processor, a property value corresponding to each of a plurality of actuators;
• determining, by the processor, whether any of the property values is outside of a predefined threshold value;
• based on a determination that a plurality of the property values are outside of the predefined threshold value,
• identifying, by the processor, the actuators to which the plurality of property values that are outside of the predefined threshold value correspond;
• determining, by the processor, locations of the identified actuators;
• determining, by the processor, a location pattern formed by the identified actuators;
• determining, by the processor, whether the location pattern meets a predefined location pattern that is indicative of a head strike;
• and
• based on a determination that the location pattern meets the predefined location pattern, outputting an indication concerning a potential head strike.

A printing system comprising:

• a printhead having a plurality of firing actuators;
• a sensor to measure a property value corresponding to each of the plurality of firing actuators;
• and
• a controller to:
• determine a count of the firing actuators having property values that are outside of a predefined threshold value range;
• based on the count exceeding a predefined maximum threshold value,
• determine locations of the plurality of the firing actuators;
• determine a standard deviation of the determined locations;
• and
• based on the determined standard deviation being below a predetermined threshold, output an indication concerning a potential printhead strike.
