Automatic bias and registration control system for electrophotographic copier |
| abstract |
In an optical imaging system for an electrophotographic copier, a photodetector intercepts a portion of unfocused light being reflected toward the photoconductive surface. An electronic circuit generates a biasing voltage for the copier development electrode which varies with the amount of light incident on the photodetector a set time after the photodetector receives a distinctively intense light pulse reflected from a high-reflectivity strip positioned ahead of the document being copied. The time delay insures that the light which determines the bias voltage has been reflected from the main body of the document. The light pulse from the high reflectivity strip can also independently actuate the copy paper feed mechanism to insure proper image registration. |
