Stencil printer with a duplex printing capability

Abstract

Disclosed is a duplex printer which is capable of performing simplex printing without wasting a master and providing a print output with a satisfactory image quality at the time of duplex printing, and which is capable of suppressing an increase in installation space while effecting adjustment on the print image position in the sheet conveyance direction. The duplex printer includes a printing section, a sheet feeding section, a sheet discharging section, an auxiliary tray, refeeding means for refeeding a sheet having an image printed on its front side, and a path selector that steers the sheet to one of the auxiliary tray and the sheet discharging section. In a duplex printing mode, a master having first and second perforated images formed thereon side by side is wound around a print drum, thereby performing duplex printing. The position of each print image with respect to the sheet in the sheet conveyance direction is adjusted by changing the timing with which the sheet is fed from the sheet feeding section to the printing section, and the timing with which the sheet is refed from the refeeding means to the printing section.
