Upon completing a print job.  The carrier returns to the cap tops..  As it approaches the cap top station there is what sounds like a "clunking" or "popping" noise.  After this noise the printer will show an error code for the scan motor. When this happens I am no longer able to go back and cut the printed piece.  The error code is not happening every time just periodically.  Any advice where to start would be greatly appreciated!!!See More
