Scanner glass foggy on the inside
We have an HP ScanJet 6300C scanner that's a few years old. I've been scanning pictures all morning and noticed they seem a little on the hazy side. I thought that was photographer-error, but I just noticed that the scanner glass is foggy on the inside! I can't find the manual for the scanner (it's around here somewhere, we've been remodeling...). Does anyone know how to clean it? And why does it get foggy on the inside?
All the time I've spent scanning photos this morningn is wasted!!!
