ABSTRACT:
An on-demand narrow web electrophotographic printer and method of printing forms a latent image and a narrow web paper feeding mechanism feeds paper from a roll for closely spaced printouts of tickets or labels, such as adhesive-backed labels, for bar codes, receipts of arbitrary length, or lottery tickets. An endless rotary latent image carrier mechanism and cutter blade are synchronized with a paper infeed mechanism, a fixing unit, and an outfeed to feed, print and cut the paper printout at a controlled length and with no paper wastage. In different embodiments, a length of paper is either accumulated in advance or drawn back to a position ahead of the drum to allow on-demand operation without sacrificing printing efficiency. Preferably, one or more web transport assemblies are separately-driven, and phase differences between image forming and sheet transport steps are accommodated by separating the sheet for printing, accumulating a feed loop in the imaging path, or actuating a drive to pull back the web during operation. This synchronization allows low-cost laser printer technology to efficiently produce short narrow-web prints on-demand.
