Electrostatographic apparatus having fusing process and system for improved toner offset control

摘要

A process and system for inhibiting toner offset in a electrostatographic apparatus of the kind wherein toner images are contact fused to a copy sheet. Drops of offset inhibiting liquid are discretely directed to predetermined locations on the contacting surface of the apparatus fuser member. For example, a drop on demand, piezoelectric drop generator can controllably jet drops of silicone oil to form desired offset inhibiting patterns in accord with apparatus control signals, indicative of particular copy sheet and image requirements.
