Notes on printing 2-dimensional symbols

When printing 2-dimensional symbols with this product, note the following points:
 We recommend using the 2-dimensional symbols with the height of 33 mm {1.30"} or less. If the height of
symbols is more than 33 mm {1.30"}, quality for scanning symbols may decline. After printing 2-dimensional
symbols, make sure they can be scanned correctly using a barcode scanner.
 When printing 2-dimensional symbols, it is recommended to set the height of 1 step of the symbol to 3–5
times the width of one module, and the total height of the code should be about 5 mm {0.20"} or more.
 When using a page mode that includes a 2-dimensional symbol, the printer uses normal mode and unidirec-
tional direction for all passes that include the 2-dimensional symbol. Because the print density changes mid-
way, we recommend printing all pages in normal mode.
 If printing a 2-dimensional symbol with a 90° or 270° orientation, it is recommended to set the minimum
module width to 0.423 mm {0.017"} or the module width to 3 or more.
 The PDF417 quiet zone (left and right, upward and downward space areas for symbols determined by the
PDF417 symbol specifications) must be ensured by the user.
