System and Method for Identifying a Particular Inkjet Ink

Abstract

A system for identifying a particular inkjet ink includes an ink delivery tubing interconnecting an ink cartridge and a printhead, a quantity of ink dispensing from the ink cartridge to the printhead by flowing through the ink delivery tubing, a light emitter configured and positioned to transmit light in a first preselected wavelength bandwidth onto the ink delivery tubing and the ink flowing therethrough, a photo sensor configured and positioned to detect light in a different second preselected wavelength bandwidth that is emitted by a fluorescent additive contained in the dispensed ink, and a signal analyzer electrically connected to the photo sensor and operable to produce an electrical output signal corresponding to such light emissions such that an electrical output signal above a given level is indicative of the presence of the particular ink in the ink cartridge.
