Label Layout

As mentioned earlier, to be properly recognized the printed bar codes printed must be a supported

symbology, have a narrow bar resolution of no less than 10 mils, and have proper quiet zone areas.

Another important factor concerns label formats with multiple-up bar codes: If printing multiple-up bar

codes in ordered columns where the same encoded information exists in each bar code (see below), there

must be at least ¼ inch white space in the rows between these symbologies.

Finally, when considering your layout, if you are going to print bar codes at high speeds that are 1/8 inch

or less, consult the following table to ensure that the Scanner will be able to properly detect the codes.

Minimum Bar Code Height

1/16 inch (1.5 mm)

1/8 inch (3 mm)

 Note: In addition to the conditions above, some special c onsiderations should be made if you are scanning small

labels.

(1) In some cases, the printer must back-up to scan the bar code because the small label size will not allow

reading until it emerges from the printer.

(2) If possible, arrange the layout so that the bar code(s) appear in the first portion on the label (as the label

exits the printer).

(3) If the barcode is large enough, or if the barcode is positioned to emerge from under the printhead before

next label starts to print, a reduction of print speed may actually improve throughput by avoiding label back-

up repositioning.

No scheduled maintenance is required for the

Scanner. Should it require cleaning, use a water

dampened lens (or lint free) cloth and carefully

clean the Window (see illustration). Avoid

excessive moisture that could penetrate the housing

and obscure the window. While the use of cleaning

fluids other than water are not recommended, if

necessary a neutral detergent or ethanol would be

preferred; never use bleach at any strength because

damage to the painted case and/or window can

result.
