(54) Inkjet printer system with auxiliary high volume input tray


(57) The invention relates to a high capacity paper supply unit (10) and method of supplying individual sheets of paper therefrom to a paper transport path in a printer (P). The high volume paper supply unit has transport apparatus therein and a pivotally mounted convex paper guide (40) and a pivotally mounted concave paper guide housing (50) at the rear of the unit define a paper path therebetween which extends generally vertically and then curves to a generally horizontal direction for feeding paper to the single sheet paper path in the printer through an access aperture (160) in the rear wall of the printer. Paper drive rollers (70) and an electrical resistance paper pre-heater (80) are mounted in the apparatus proximate the discharge end of the paper path such that pre-heated paper can be immediately fed at the appropriate location of the paper path in the printer, preferably an inkjet printer.
