Droplet ejection head control device and control method, and program storage medium
Abstract:
A droplet ejection head control device includes a pressure alteration section, a detector and a controller. The droplet ejection head is provided with plural nozzles and is supplied with a liquid. The pressure alteration section alters a pressure inside the droplet ejection head. The detector detects a position of a boundary of liquid which is exuded onto a nozzle face from at least one nozzle of the droplet ejection head in accordance with the pressurization at the inside of the droplet ejection head. After the pressurization of the interior of the droplet ejection head commences, the controller controls the pressure alteration section on the basis of detection results from the detector such that the pressurization is stopped just (immediately) before respective boundaries of the liquid exuded onto the nozzle face from neighboring nozzles come into contact.
