Methods and systems for detecting ink droplets ejected by a printer, and for determining if the trajectory of an ink droplet deviates from a desired trajectory. In one embodiment, the ink droplet trajectory detector has multiple electrically conductive, electrically isolated sensors. Each of said sensors is configured to generate an electrical signal when an ink droplet passes in proximity thereof, without requiring the ink droplet to physically engage any portion of said sensors. The ink droplet trajectory detector also has at least one structure orienting said sensors relative to one another.
