White level stabilization for tri-level imaging |
摘要 |
Stabilization of the white or background discharge voltage level of tri-level images is accomplished by monitoring photoreceptor white discharge level in the inter-document area of the photoreceptor using an electrostatic voltmeter. The information obtained thereby is utilized to control the output of a raster output scanner so as to maintain the white discharge level at a predetermined level.
