ABSTRACT:
Image-forming apparatus includes a finite length image member such as a seamed photoconductive loop. Images are formed on the image member in one of three different sized image frames, the first image frame being 1/2 the in-track length of the third image frame and the second image frame having an intermediate length. Relatively small size images, for example letter size images are formed in the first size frames while relatively large sized images, for example, ledger sized images are formed in the third size frames. Intermediate sized images, for example images for B-4 receiving sheets are formed in the second or intermediate size image frames. Receiving sheets in duplex are passed through a finite length duplex path which has a speed profile which is substantially the same for receiving sheets bearing images formed in the first and third frame lengths but is different, for example faster, for images formed in the second size image frame while use of the same duplex path for the three frame sizes. Sheets are fed into an inverter in the duplex path at a faster speed than is used for most of the rest of the duplex path. After a delay in the inverter, sheets are fed out of the inverter at a substantially reduced speed more easily handled by the downstream portion of the duplex path.
