The length of the scan profile printed is proportional to the Beam
Width setting (page 82) and depends on the Profile H Mag setting
(page 78).
The scan profile will print either a 1.5 inch wide or a 3 inch wide
graph depending on the Label Width setting (in the MEDIA
CONTROL menu). (Label widths less than 4 inches print the
smaller 1.5 inch wide profile.)
Printing is done in continuous mode without taking into account
media gap/marks.
NOTE: Use continuous media or else the scan profile may distort
at the media gap/marks.
The following figure shows a sample scan profile graph. It only
shows the profile of actual bar code data. The dashed lines
represent the 90% and 10% marks. You can use these to help set
the gain and offset (if necessary).
