KONTINUIERLICH ARBEITENDER FLUESSIGKEITSSTRAHLDRUCKER UND VERFAHREN ZUM BETREIBEN DES DRUCKERS

摘要

The invention relates to a process for operating a continuously operating fluid jet printer, having a nozzle for generating a fluid jet, at least one charging electrode, a device for controlling the charging electrode, a device for generating an electric field in which the droplets are deflected according to their charge, and a device for collecting droplets not required. Working parts (5, 7) of the printer downstream of the nozzle are removed from the range of the jet while the jet is being built up or run down during starting and stopping. Also disclosed are:- (a) Using a fluid other than ink during start-up or shut-down. (b) Moving the waste ink collector (gutter) towards the nozzle. <IMAGE>
