This is caused when mechanical parts of the printer get out of alignment. This happens only rarely and you may never experience it at all throughout the life of the printer. If you do have problems, use the following procedure to correct it.

4.If the two lines do not align properly, use SET/PARK/EJECT to move the lower line to the left or LINE FEED to move it to the right.
