A clean-in-place system is disclosed for use in an ink jet printhead (10). The clean-in-place system features a compartment (17) in which the printhead components (18a, 20, 22, 24) are disposed. An end plate (28) has a slot (26) therein to permit ink drops to be projected from the compartment (17) onto a substrate to be marked. For cleaning purposes, a pneumatic shutter (42) is disposed adjacent the slot (26) to seal it. Thereafter, the compartment (17) is flooded with ink solvent (107) by means of a pump (103) from a solvent reservoir. The solvent may be agitated by air or mechanical means. Thereafter, a drain line (116, 117) is used to remove the solvent from the compartment (17) and air is blown therethrough to dry the components. The pneumatic shutter (42) is reopened after the solvent is withdrawn to enhance the drying of the components. The shutter (42) may consist of an inflatable tubular member and a pump for supplying compressed air to the tubular member (42) to inflate and deflate it.

On décrit un système de nettoyage interne d'une tête d'impression à jet d'encre (10), qui présente un compartiment (17) dans lequel sont disposés les éléments de la tête d'impression (18a, 20, 22, 24). Une plaque d'extrémité (28) comporte une fente (26) à travers laquelle des gouttelettes d'encre sont projetées du compartiment (17) sur un substrat destiné à être marqué. Aux fins de nettoyage, un obturateur pneumatique (42) est disposé adjacent à la fente (26) pour la fermer. Le compartiment (17) est ensuite inondé d'un solvant d'encre (107) à partir d'un réservoir à solvant, au moyen d'une pompe (103). Le solvant peut être agité par de l'air ou par un moyen mécanique. Une conduite de vidange (116, 117) est ensuite utilisée pour évacuer le solvant du compartiment (17), puis de l'air est soufflé à travers ladite conduite pour sécher les éléments. L'obturateur pneumatique (42) est rouvert après évacuation du solvant pour améliorer le séchage des éléments. L'obturateur (42) peut être constitué d'un élément tubulaire gonflable et d'une pompe pour injecter de l'air comprimé dans l'élément tubulaire (42) pour le gonfler ou le dégonfler.
