Title (EN) PRINT DEVICE WITH VALVE IN PRINT FLUID SUPPLY PATHWAY
(FR) DISPOSITIF D'IMPRESSION AVEC VALVE DANS LA VOIE D'ALIMENTATION EN FLUIDE
Abstract:
(EN) In one example, there is disclosed a print device (100) comprising: a print fluid supply pathway (102) extending from a reservoir inlet (104) to a printhead outlet (106); a valve (108) in the print fluid supply pathway (102) downstream of the reservoir inlet (104); a pressure sensor (110) to monitor print fluid pressure upstream of the valve (108); a pressure sensor controller (112) to temporarily close the valve (108) for a closed period and monitor print fluid pressure using the pressure sensor (110) during the closed period; and a print operation controller (114) to control printing operations of the print device (100) so that in use a printing operation continues and print fluid is discharged from a printhead (234) during a closed period of the valve (108) in the respective print fluid supply pathway (102).
(FR) Selon un exemple, l'invention concerne un dispositif d'impression (100) comprenant : une voie d'alimentation en fluide d'impression (102) s'étendant d'une entrée de réservoir (104) à une sortie de tête d'impression (106); une valve (108) dans la voie d'alimentation en fluide d'impression (102) en aval de l'entrée de réservoir (104); un capteur de pression (110) servant à surveiller la pression de fluide d'impression en amont de la valve (108); un contrôleur de capteur de pression (112) servant à fermer temporairement la valve (108) pendant une période fermée et surveiller la pression de fluide d'impression grâce au capteur de pression (110) pendant la période fermée; et un contrôleur d'opération d'impression (114) servant à commander des opérations d'impression du dispositif d'impression (100) de façon que, pendant l'utilisation, une opération d'impression continue et du fluide d'impression soit éjecté d'une tête d'impression (234) pendant une période fermée de la valve (108) dans la voie d'alimentation en fluide d'impression respective (102).
