Abstract
A printhead auto-alignment detection system includes a UV LED configured and positioned to transmit light in ultraviolet wavelengths onto a printed printhead alignment pattern formed using an aqueous ink having a UV fluorescing material. A sensor is configured and positioned to detect light in visible wavelengths emitted by the fluorescing material. A controller is communicatively coupled to the UV LED and the sensor. The controller is configured to execute program instructions for controlling the output of the UV LED and for reading a signal output of the sensor during a printhead alignment operation.
