Abstract

Disclosed is a design of an imaging zone for a Thermal Ink Jet (TIJ) printer that keeps a sheet of paper flat to maintain a precise printhead-to-paper gap control, regardless of paper thickness. Paper is kept flat by tensioning it prior to imaging and by locating its image side directly to the printhead. Additionally, this imaging zone provides a wide drying zone for a non-contacting backside radiant heater and provides for acceptably small lead and trail edge margins for the user's document.
