METHOD AND APPARATUS FOR MACHINE SPECIFIC OVERCURRENT DETECTION |
| 摘要 |
<p>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.</p> |
