About 2-Level Roll Switching
This printer allows you to load roll paper in two levels. The upper level (Roll 1) and the lower level (Roll 2)
can be automatically switched depending on the print job.
Printing by automatically switching Roll 1 and Roll 2 in this way is called "2-level roll switching."
• For instructions on setting the paper, see " Setting the Paper Rolls in the Printer According to the
Intended Use ."
• For the 2-level roll switching procedure, see " Printing by Automatically Switching Upper-level and Lower-
level Roll Papers ."
• Guidelines on how to switch Roll 1 and Roll 2 for certain cases are summarized in " How to Switch Paper
Rolls ."
