IS8000 HoloTrack series scanner does not scan all presented barcodes The scanner did not work normally 50 % of the barcodes can?t scan, 20% of barcodes were wrong. IS8500 - does not scan the same as an identical unit Why IS8500 did not work normally?
Scanning Hardware: IS8xx Holotrak
If the scanner powers on and scans some of the barcodes but not all, do a test by pointing it to a flat surface at a 90 degrees angle and check the laser pattern. The laser lines should be parallel and equidistant to each other like seen in the Metrologic HoloTrak IS8000 Series Holographic Scanners User Guide, available here. If the lines are crooked and closer together in some places then in others, then the unit needs to be sent in for repairs.
