(2) Print Weight Adjust Function
This function improves scanning bar codes comprised with thick or thin bars. The improvement can
be selected in seven grades. In ordinary condition, the setting is not required to change. However, it
is useful to change it if scanning a particular bar code is difficult.
(3) Decode window function
ⅰ This function specifies the decode range, centered on the position that the aimer is firing at. If
multiple symbols are printed on one form, this function is an effective way to decode only certain
symbols.
ⅱ If mode1 and mode 2 are specified for the decode window, the decode range is determined
automatically so that only the symbols near the center are scanned.
ⅲ If user settings are specified for the decode window, specify the area around the center which
includes the coordinate center (416, 320). The decode range can be specified with coordinates.

When using the decode window to scan a symbol, the scan can only be performed when a part of
the symbol is contained within the decode window. In the figure below, symbol A cannot be scanned
because it lies completely outside of the decode window, but symbol B can be scanned because it
lies partially within the decode window.
A
The position illuminated by the aimer is a guide. It may change due to the distance between the symbol
and the scanner, the angle, and other factors.
