A unique system and method for directly feeding sheets into a printing device having a moving image conducting element with a plurality of images placed thereon for transfer to sheet paper and having a wait station for controlling the timing of paper transfer to the image conducting element provides a feeding table to transfer sheets from a source to a printer stack deshingler while bypassing and, thus, eliminating any need for sheet stacks. The movement of each sheet by the wait station into the image transfer element signals the cutting of a sheet from a roll of continuous web on the input side of the feeding table. Once the sheet has moved into the image transfer element the absence of a sheet at the detector signals transfer by the feeding table of the cut sheet to the stack deshingler. Simultaneously, a source of web presents and end of the web representing another sheet to a cutting unit. This sheet is (out when the current sheet at the wait station begins movement into the image transfer element.

[ What is claimed is:] [1.] An apparatus for feeding sheets to an input port of a utilization device, the input port adapted to be fed from a first source of sheets along a first feed path, the apparatus comprising:a second source of sheets;a support structure defining a second feed path for guiding sheets from the second source of sheets toward the input port, the support structure having an upstream end and a downstream end;a drive mechanism that selectively moves sheets on the support structure along the second feed path from the upstream and to the downstream end of the support structure and toward the input port;a sensor system that signals a position change of a sheet at the downstream end relative to the input port; anda controller that controls the drive mechanism to maintain an upstream position sheet in a substantially stationary position in response to a signal of the sensor system indicating movement of a downstream position sheet to the input port and to drive the upstream position sheet to a predetermined waiting position in readiness for introduction to the input port in response to a signal of the sensor system indicating that the downstream position sheet has reached a more downstream position within the input port.
