Using Pre-Printed Receipt Media
The ZQ220 printer supports alignment of pre-printed receipts by
using the out of paper sensor located near the printhead.
Black Mark Dimensions (Receipt Media)
The reective media black marks (or black bar/marks) should
extend past the centerline of the roll on the front side of the paper.
• Minimum mark width: 0.59 in. (15 mm) perpendicular to the edge
of the media, and centered within the width of the roll.
• Mark length: 0.19 - 0.24 in. (4.8 - 6.0 mm) parallel to the edge of
the media.
Label Areas
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.
