Question about HP ScanJet 2400 Flatbed Scanner
I have a hp scanjet 3500c that went into troubles. It produces only negative, greeny and fuzzy images as in the attached figure. I I suspected the power supply and I replaced the 5V voltage regulator LM340 since it crashed when using a cheap (no name) power adaptor. No effect. Does anyone knows what would be the defective part?
My scanner scans but nothing appears except for pink or magenta on the whole page. What do i need 2 do 2 fix it?
