Title
(EN) FLUID EXTRACTION USING FILL PUMP ACTIVATION
(FR) EXTRACTION DE FLUIDE PAR ACTIVATION DE POMPE DE REMPLISSAGE
Abstract
(EN)
In one example in accordance with the present disclosure, a fluid extraction system is described. The fluid extraction system includes an interface to fluidically and electrically couple a removable extraction reservoir to a printing device. A supply line of the fluid extraction system transports fluid from the interface to a reservoir of the printing device. A return line of the fluid extraction system is coupled to the reservoir and supply line and transports fluid from the reservoir to the interface. The fluid extraction system also includes a switch to, responsive to removal of the removable extraction reservoir from the printing device, activate a fill pump to draw fluid through the supply line away from the interface.

La présente invention concerne, selon un exemple, un système d'extraction de fluide. Le système d'extraction de fluide comprend une interface destinée à coupler fluidiquement et électriquement un réservoir d'extraction amovible à un dispositif d'impression. Une conduite d'alimentation du système d'extraction de fluide transporte le fluide de l'interface vers un réservoir du dispositif d'impression. Une conduite de retour du système d'extraction de fluide est accouplée au réservoir et à la conduite d'alimentation et transporte le fluide du réservoir à l'interface. Le système d'extraction de fluide comprend également un commutateur pour, en réponse au retrait du réservoir d'extraction amovible du dispositif d'impression, activer une pompe de remplissage pour aspirer le fluide à travers la conduite d'alimentation loin de l'interface.
