Abstract
A printer autocontrast system measures the current passing from a toner reservoir to a charged dielectric member which receives toner from the reservoir. The charge delivered to the drum in this way is scaled and compared to an estimate of the intended image charge to develop an error signal. The error signal corrects a control parameter to adjust the operation of an electrographic printhead which forms a latent image on the dielectric member.
