Is this normal?  Sometimes when I go to scan something, I get a message on the screen that the "scanner bulb is warming up".  It seems do this every now and then, but it only takes 5-6 seconds, and then the scanner is off to the races...Also, it seems to only do that when I have something on the flat bed scanner.  Meaning, not when I feed it through the ADF.

Comments from anyone?  Has anyone else seen this?
