英文摘要 | An imaging device has a photoconductor with a surface that is selectively discharged by a light from a laser diode to create a latent electrostatic image for attracting toner for transfer to a media. A circuit drives the laser diode. The circuit has a switch for turning on and off the light, a resistor complementary to the laser diode selectively connectable to the switch, and a passive circuit component coupled to the laser diode. The passive circuit component is a delay line, inductor, choke, coiled wire, or ferrite bead is contemplated. It may also typify a length of copper tracing on a printed circuit board that supports the laser diode. The circuit causes an initial overshoot voltage spike in an on voltage pulse that is about 20% or more than the settled on voltage. The voltage spike dampens out in about one-fourth of a total voltage on time of the pulse. |
