I own the HP 2. I have read threads on here that the latest version for this scanner is 2.05. So I checked my version and it states it is 1.05. So I connected the scanner to my PC and checked for firmware update and it tells me I have the latest version. I don't see how that is possible if my version is 1.05. Any ideas why I am getting this info? Just a thought is there a different version of the Sentinal software which would give me this bad info.? Thanks for any help
