Our HP ScanJet 3500 f1 suddenly has a thick vertical black line in each page. We've had it about 3-4 months and used it lightly so far, so this sudden problem is a surprise. This started today and affects all pages scnaned so far, from both the HP software as well as importing thourgh other software (Acrobat, Photoshop, etc.), from the flatbed scan glass. The glass and sheetfeed rollers are clear. Is there any hardware problem in this scan unit?
