I have a Hewlett Packard ScanJet 3300C computer scanner which i bought a few years back. After using it a few times when it was still new, i stopped using it because i was not so desperate to scan pictures at that time. Now, a few years later, i have pictures that i want to scan. However, even after the scanner was plugged in all the right ways, the scanner showed no light, no life. Nothing happens when i press the buttons of the scanner. A friend said it could be an internal problem caused by lack of use. I would like to know if this is the most likely cause of the scanner not functioning, and if yes, then what needs to be changed or repaired?
