Title (EN) METHOD AND APPARATUS FOR MACHINE SPECIFIC OVERCURRENT DETECTION
(FR) PROCEDE ET APPAREIL PERMETTANT DE DETECTER UNE SURINTENSITE SPECIFIQUE D'UNE MACHINE
Abstract: front page image
(EN)The invention is drawn to a test circuit for an ink jet printer which measures the voltage decay over time. Specifically, the test circuit utilizes a known resistor connected to the power source (voltage) and the printer. The printer functions as a capacitor to complete the test circuit as a RC circuit. After isolating the power source from the test circuit, the voltage decay is monitored to indicate the presence of a short circuit.
(FR)L'invention concerne un circuit d'essai destiné à une imprimante à jet d'encre permettant de mesurer le déclin de la tension pendant une durée. Le circuit d'essai utilise, plus spécifiquement, une résistance connue connectée à une source d'alimentation (tension) et à l'imprimante. Ladite imprimante fonctionne comme un condensateur afin de compléter le circuit d'essai sous forme de circuit résonant. Après isolation de la source d'alimentation du circuit d'essai, la diminution de tension est surveillée afin d'indiquer la présence d'un court-circuit.
