better adjust the printing home position with the software.)
9. When you finish printing (the printer receives no data for several seconds) the printer feeds the
perforation of the tractor paper to the edge of the printer cover so that you can tear off the last
sheet.
Note: Set the auto tear off function in the Print Setting mode on. Otherwise, the printer does
not feed the perforation to the edge of the printer cover automatically.
10. If the perforation and the edge of the printer cover do not match, you should adjust the paper
position following the steps in “Micro adjust” and tear down the paper having been printed.
When you send print data again, the paper automatically feeds back to the printing home
position and ready to print.
How to switch tractor paper to cut-sheet paper
