A mailing machine comprising a printer module, a transport device and a controller in operative communication with the transport device and the printer module. The printer module including an array of ink jet print elements for printing on an envelope and a repositioning device in operative engagement with the array of ink jet print elements for moving the array of ink jet print elements between a maintenance position and a print position. The transport device including suitable structure for feeding the envelope in a pathof travel so that the envelope passes in opposed relationship to the array of ink jet print elements when the array of ink jet print elements are in the printposition. The controller keeps an indicator of an amount of time elapsed between printing successive envelopes. If the indicator reaches a predetermined threshold, then the controller causes the array of ink jet print elements to perform a maintenance operation by firing the array of ink jet printelements in the absence of the envelope while the printer module is in the print position.

Machine de traitement de courrier comprenant un module d'impression, un dispositif de transport et un dispositif de commande associé au dispositif de transport et au module d'impression. Le module d'impression inclut un ensemble d'éléments d'impression à jet d'encre permettant d'imprimer sur une enveloppe et un dispositif de repositionnement associé à l'ensemble d'éléments d'impression servant à déplacer ces derniers entre une position d'entretien et une position d'impression. Le dispositif de transport inclut une structure permettant de distribuer l'enveloppe sur un trajet afin de la faire passer en relation opposée à l'ensemble d'éléments d'impression lorsque ces derniers sont dans la position d'impression. Le dispositif de commande maintient un indicateur de la période de temps écoulée entre les impressions d'enveloppes successives. Si l'indicateur atteint un seuil prédéterminé, alors le dispositif de commande provoque l'entretien des éléments d'impression en déclenchant ces derniers en l'absence d'enveloppes lorsque le module d'impression est dans la position d'impression.
