A method for detecting electrostatic discharge (ESD) events in an imaging device includes scanning a target placed in a scanner to create a scanned image of the target. The scanned image has a plurality of scan lines with each scan line having a number of pixels or samples. For each of the plurality of scan lines, a determination is whether or not the number of pixels or samples of the scan line matches a respective predetermined number of pixels or samples, the predetermined number of pixels or samples being based upon a resolution setting of the scanner. Upon determining that the number of pixels or samples of the scan line does not match the predetermined number of pixels or samples, a count value is incremented. The count value is used as a healthcheck data to indicate at least one ESD event has occurred in the imaging device.
