So I have an HP scanner (Scanjet G4010) and until I updated to Mavericks, it worked fine. But since then, when I try to save a scanned image, it either flashes an error message or it saves an all-black picture. Please help, I tried to update the software, but it says the software update program doesn't currently work. I tried re-installing it, but it's the same. I tried emailing HP, but they apparently don't have an email. I don't know what else to do. Help!
