This happens primarily when close to the end of the media roll whenthe curl is the worst.CAUSEThis problem occurs in the media transport at the point where the media turns and meets theregistration roll shaft. Because there is no registration feed roll in this area of the transport. themedia catches the edge of the inner extrusion of the media transport.SOLUTION( Figure 1): Order a dog ear repair kit 600K62600, remove the transport and install mylar stripsin the area shown in the illustration.The registration roll and transport design was changed to add an additional set of registrationfeed rolls ( TAG 12). Some early machine with this tag did not get marked on the tag matrix.This transport may be identified in the following manner, without removing it from the machine:1. Open the cutter drawer .2. Check the left side of the transport. If the label is marked “12 roll” this kit is not neededand something else in the media path is causing the problem.
