Problems with your point of sale scanner

There may be some problems with your point of sale scanner. The scanner might not work correctly all the time. You can change the angle and make it work, but then it may malfunction even more after some time. The most common cause of it may be a dirty lens. But, you must be careful when you clean it because you do not want to scratch the lens.

Key Takeaways:

• The most common cause is a dirty len. In retail, fingerprints, smudges, dirt, often glues from sticky tape, etc. are all collecting over time on the lens and progressively having an impact upon the quality of your scanning so slowing you down.
• If the scanner is working fine, stop do not clean it even if it does not look right. If you think, you should do a clean first do a visual check on the lens to see if its required.
• If that is not enough and there are difficult marks to remove, I then use a len cleaning tissue, which are available. The ones I prefer are alcohol based as they remove fingerprints and glue without leaving streaks.

“Sometimes what happens is that your scanner does not work occasionally. You change the angle of reading, and it works for a while and then progressively gets worse. The most common cause is a dirty len. In retail, fingerprints, smudges, dirt, often glues from sticky tape, etc.”
