This is certainly one curly problem coonsanders.
It works it doesnt work.
I'm certainly out of ideas.
Maybe manish07 is right, they might be able to do something for you.
Seeing you've had a session without blue streaks it suggests that the drivers are the issue and its nothing mechanical or electrical, nor is there a problem with the internal workings of the scanner, such as mirror alignments or the diffusers or lenses.
tell u the whole story..ok..i had 2 hp products installed my computer the hp all-in-one 4215 printer and the hp 3670 scanjet scanner.ok ...the printer needed more black ink because the scanned (with the printer)i saw blue streaks in the scanned photo.these blue streaks are an indication of needing an ink refill.
ok i uninstalled the printer to fix the problem and just use the scanner as it uses no ink.
i just recently noticed the scanner too is leaving these blue streaks as did the printer
did.i contacted hp tech and the forums too.hp tech said it was locked up thats the reason for the blue streaks.

Have you tried replacing the ink cartridge? (Although I cant see how that would affect the scanner.)
Have you tried to reinstall the previous drivers for the deleted component, or reinstalled the other HP printer you removed?
