"The MC9090 showing slight condensation on the screen after being moved from the freezer to the coffee room" this is the description about the MC9090G CR testing in freezer about -22 deg.C.  However, in my test, I put MC9090G CR into fridge about -18 deg.C. The scanner exit window was freezing with some ice or frost on double side of the glass. The problem is inside the glass should be clear, otherwise the ice/frost will block the laser line, it cannot scan barcode even after cleaning the outside of the glass. Did anyone ever use such device in freezer, and share your experience? Is my test result normal? Or the desiccant should be changed? The device is new one manufactured in Feb 2012. it's appreciated for any comments and suggestion. Thanks.
