This is not recommended practice (having a seperate connection to the scanner from each page/form). It will always tend to cause the sort of problems you are seeing (as well as other, more subtle ones). The recommended way to resolve this is to place the scanner object in a wider scope (say at application level) and then use each form to Enable/Disable the scanner object (rather than Open/Close it). Open/Close always comes with an overhead (it actually turns on and off the power to the scanner hardware in most cases). Enable/Disable can be achieved by Submitting (Enable) and Flushing (Disable) a scan on an already Opened scanner. This sort of example use is shown in the ScanSamp3 applications in the EMDK.

Also, take a look at the fix for SPR 19400.

Thanks for the tip -the spr fix worked. I did not find the spr fix as we normally search for MC3100 or via mobile computer 3100 and both did no list this fix. Thanks for the quich response
