Suggestion
Check synchronization of reading pulse with
object to read.
Is the scan line correctly positioned?
Place barcode in the center of scan line and
run TEST MODE (selectable by Genius™ as
Operating Modes).
If you still have troubles, check the following:
Is the reading distance within that allowed
(see reading diagrams)?
Is the Tilt angle too large?
Is the Skew angle less than 10° (direct

Is the barcode quality sufficient?
If you had no success, try to perform the test
using the BARCODE TEST CHART included

If working in PackTrack™ mode, verify that
the coordinates (in particular the Y axis) are
correct.
Is serial cable connected?
Is correct wiring respected?
If using MAIN RS232 or RS485 interface, is
the reference ground connected to proper
SGND Main Isolated (also referred to as
