The full cut is a setting available from the
dealer. Full cut should be selected only
when the printer is installed horizontally.
Never change the printer from partial cut
to full cut after it has been used. Never
leave pieces of cut paper in the paper exit.
Be sure to change the paper guide spacer
if paper of a different width is used. Then,
set the customized value in printer memory
for the correct paper width. For details
about how to set the paper width, see
Chapter 6, "Installation."
