Title
(EN) FLUID EXTRACTION USING BYPASS LINES
(FR) EXTRACTION DE FLUIDE À L'AIDE DE LIGNES DE DÉRIVATION
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 return line of the fluid extraction system is to connect the interface and a reservoir of the printing device. A bypass line is to 1) connect the return line and the reservoir and 2) redirect fluid from the return line to the reservoir following removal of the removable extraction reservoir. A switch of the fluid extraction system is to, responsive to removal of the removable extraction reservoir from the printing device, open the bypass line to draw fluid through the bypass line into the reservoir.

Un exemple selon la présente invention concerne un système d'extraction de fluide. Le système d'extraction de fluide comprend une interface destinée à coupler électriquement et fluidiquement un réservoir d'extraction amovible à un dispositif d'impression. Une conduite de retour du système d'extraction de fluide est destinée à relier l'interface et un réservoir du dispositif d'impression. Une conduite de dérivation est destinée à (1) relier la conduite de retour et le réservoir et 2) rediriger le fluide de la conduite de retour vers le réservoir après le retrait du réservoir d'extraction amovible. Un commutateur du système d'extraction de fluide est destiné, en réponse à l'élimination du réservoir d'extraction amovible du dispositif d'impression, à ouvrir la ligne de dérivation pour aspirer le fluide à travers la conduite de dérivation dans le réservoir.
