3.3 Label Orientation Mode
As shown below, this mode allows the unit to read bar codes only in the specified
orientation when bar code labels are moving both in the forward and reverse
orientations.
* Normally, the unit can read bar codes regardless of the orientation.
• An reading error is issued when the unit reads a bar code label running in the
orientation which is not specified.
• The above chart applies to the single label read mode. You can also use this
mode together with the desired multi-label read mode. However, in any case,
the unit reads bar codes running in the specified orientation only.
• You can specify the orientation individually for Codes 1 to 4, such as specifying
“forward orientation” for Code 1, and “reverse orientation” for Code 2.
