Droplet deposition apparatus

Droplet deposition apparatus comprising:

• a first plurality of fluid channels disposed side by side in a first row extending in a first direction;
• an actuator having a plurality of actuator elements;
• drive circuitry for supplying actuating electrical signals to said actuator elements, each of said first plurality of fluid channels having a nozzle opening thereinto and each of said actuator elements being actuable to eject a droplet of fluid in a second direction, perpendicular to said first direction, from a respective one of said first plurality of fluid channels through the nozzle of said fluid channel;
• and
• one or more fluid conveying conduits comprising a first fluid conveying conduit for conveying droplet fluid to each of said first plurality of fluid channels, each of said one or more fluid conveying conduits extending in said second direction so as to convey said droplet fluid parallel to said second direction and a second fluid conveying conduit for conveying droplet fluid away from each of said first plurality of fluid channels;
• and
• a support member having a mounting surface extending substantially in said first and second directions, said drive circuitry being mounted on said mounting surface;
• wherein said first and second fluid conveying conduits are fluidically connected in series via said first plurality of fluid channels such that, during use, fluid is conveyed from said first fluid conveying conduit, through said first plurality of fluid channels, past said nozzles, and into said second fluid conveying conduit.
