Basic Operations
Scanning Guidelines
The POWERSCAN D8590 makes reading the most difficult direct part marks easy. The
following guidelines will help ensure optimal performance:
•
In the default illumination setup, allow the POWERSCAN D8590 to run through its illumination
sequences before terminating the read cycle. The POWERSCAN D8590 captures several
images with each illumination zone, evaluating the optimum settings. If reading the
same part or same part type, the POWERSCAN D8590 always uses the most recent
good read settings as a starting point so subsequent reads will be faster.
• Hold the POWERSCAN D8590 still – d
o not swipe or
move the imager. Pull the trigger
and hold until a read is indicated by the green LED.
• Hold the POWERSCAN D8590 such that its front surface is pa
rallel to the mark surface,
and the mark is centered. Unlike other readers that require a tilt to read, the POWERSCAN
D8590 is designed to operate this way.
Correct – Move in steadily with front
of imager parallel to surface.
• The POWERSCAN D8590 features omnidirectional decoding. Centering the mark within
the field of view will yield the best decode performance.
