Install the newly loaded tape into the Plex, and pull any excess to the left. Don't worry, when you power it up after a minute or so the excess will be drawn into the cartridge. Occasionally this doesn't occur, and I think the reasons are that there is too much tape in the outside splices, and/or the tape inside on the reels is too tight. So, try to keep the splices about 12 inches each before splicing, and don't tug on the reels when installing them in the cartridge.
