Methods for measuring laser performance in laser printers. |
摘要 |
<p>A method is disclosed for measuring the performance of individual lasers in a multiple channel laser printer. A laser is first preheated and then a test cycle is begun as follows. The laser is first set to a point just below but substantially equal to its threshold value and then set to a test value by supplying it with a preselected current pulse within its operating range. The power output of the laser is then read a substantial number of times and the average value of the readings of laser power output is recorded. The test cycle is repeated for a substantial number of different test values with respectively different preselected current pulses within the laser's operating range. <IMAGE></p> |
