To permit accurate adjustment of the direction of projection of droplets from a droplet generating head of a jet printer, the jet body is mounted for rotational movement in a cradle formed on, or on an arm member extending from, a support body. Charging electrodes can also be mounted on, or on an arm member extending from, the support body. The support body can be mounted on a shaft in the jet printer. Arrays of droplet generating heads can be formed by supporting a plurality of heads on a single shaft, or by constructing a plurality of support bodies from a single block of electrically insulating material. |
