Abstract
A continuous inkjet printer (5) having a printhead (7) that includes first and second ink droplet generators (8, 9), each operable to generate a stream (10) of ink droplets, and a common gutter (11) arranged to receive unprinted ink droplets from the first and second ink droplet generators (8, 9), the printer (5) further including control means configured to determine receipt into the common gutter (11) of ink droplets from the first and second ink droplet generators (8, 9), wherein the control means are operable to use a single sensor (17) to determine receipt into the common gutter (11) of ink droplets from one, both, or neither of the first and second ink droplet generators (8, 9).
