USER’S GUIDE
M7220 Wireless Hand-held Terminal
Data Capture and Bar Code Scanners
The M7220 hand-held computer comes standard with a laser scan engine that is capable of scanning
single dimensional bar codes. Optionally, Long Range Lasers and 2-Dimensional Area Imagers can be
ordered for the M7220.
Bar code symbologies are always measured in mils. This usually refers to the narrowest bar width. One
mil equals 0.001”, therefore a 0.01” wide narrow bar would be a 10 mil bar code.
Conversion: 1 mil = 0.0254 mm
1 inch = 25.4 mm
Laser Style Scan Engines
Laser-type scan engines use a stationary laser reflected by a moving mirror and a highly sensitive laser
detector. The Long Range and Advanced Long Range scan engines allow for a much greater distance
between the symbol and operator. All laser scan engines have the ability to produce a aiming dot to
assist the operator in correctly reading symbols at longer distances.
