    Occasionally losing laser on TC55

    Ronald Cavil

      We are beta testing a custom built scanning app on about 10 TC55's.  On all the units, there has been sporadic reports of users losing their scanning lasers.  Some get it more often than others, with a bad day being 3 times that the laser isn't present.  And for the people that do get the issue, some days they don't have any problems at all.  Most of the time a reboot solves the issue, but occasionally several reboots maybe required for the laser to come back.  The issue has been hard to narrow down and reproduce.  Here is some information on our setup:

       

        Hardware:                   TC55

        Android:                      4.4.3

        EMDK:                        5.0.3.0

        Build Number:            02-65-00-KG-00-MV

        Zebra patch version:  CFE-TC55-K-xx-2.65-G-00-02vB

       

      For our software, we are using the ITScriptNet product form z-space.com.  The software vendor has tried a few fixes, but it hasn't made a difference.  They suggested that we upgrade our original EMDK version from 3.1.38 to 5.0.3.0, which we did, but it hasn't made a difference.  I'm curious if anyone might have some suggestions for us to try.

          Initially I was going to suggest that there may be another application loaded and had the scanner locked from being used. But then you mentioned that you need a few reboots to clear things out. Check to see what apps may be loaded at startup. Otherwise it sounds like a possible hardware problem (unless you say it happens on multiple devices).

           

          Also the latest version of EMDK For Android is 6.0 - be sure to run the device update APK that comes with the installation in order to update the EMDK service on the device.
