A device for use in electrophotographic printing machines enabling paper tray bypass and transport to a remote finisher is disclosed. The bypass and transport mechanism may be retrofitted into output trays and bin stackers of various optical or laser printing devices. The enabling adjustable cam positioning device is comprised of two cams 1, mounted on a shaft 5 with pressed fit blocks 2 engaging the cams, an adjustable screw 3 and opposing spring 4 for varying the eccentricity of the cam relative to the shaft as shown in Figures 1A (concentric) and 1B (fully eccentric). The adjustable cam assembly 1 is positioned in the bypass transport 7 as shown in Figure 2. The shaft 5 bearing two cams is parallel to the output process direction 8. Attached to the shaft at one end is a handle which is used to engageldisengage the two colinear cam assemblies to/from the vertical wall of the stacker tray 6. The flat edge of the cam is positioned flush against the tray wall when in use to maintain the assembly firmly in place. When the bypass transport is in place in the stacker tray 6, all copy sheets are bypassed to a second finishing device. The cams are adjustable to account for different sizes of various trays due to tolerances. When the cams are properly adjusted by a service technician during initial installation, the bypass transport will be held firmly in the tray and the mating paper paths will remain aligned. After initial installation, a '
