(3) When using a new paper roll, remove the glued portion of the
paper as well as the part to which adhesive tape is affixed.
Caution: Since the glued portion of the paper should not be printed on,
remove about one turn (about 40 cm) of the roll paper from the
beginning so that none of the remaining paper has glue on it.
Any adhesive or other matter remaining from the glue may
adhere to the thermal head and cause a problem, such as voids
on printouts. Therefore, do not forget to remove the glued
portion of the paper.

below.
Caution: Pull out the paper until enough of it protrudes past the front cover of
the Printer.
