摘要 |
This invention relates to circuitry for non-impact printers that use light emitting diodes (LED's) to produce an image on a photoconductor and for controlling the output of each LED of a light emitting diode array that is part of the printer. A binary weighted duty cycle control is used to obtain substantial uniformity in the light emitted from each LED. The binary cycle is time related so that through use of a four-bit code, sixteen outputs are available which yield sixteen periods during which an LED may be enabled. |
