The media/black bar sensor detects the dark, pre-printed bar
on the media, so a path in the center of the paper must be kept
free of dark, pre-printed graphics.
Note • Dark, pre-printed graphics refer to any symbols,
barcodes, text and/or colored areas that have been applied to
the receipt paper rolls before they have ever been used in the
printer.
