【発明の名称】プリンタ自動コントラスト制御装置
Document Type and Number:
Japanese Patent JP3144795
Kind Code:
B2
Abstract:
A printer autocontrast system measures the current c(t) passing from a toner reservoir (26) to a charged dielectric member (20) which receives toner from the reservoir. The charge delivered to the member (20) in this way is scaled at 30 and compared at 50 to an estimate E(Q) 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.
