I am asking this question here because I am getting=20 absolutely nowhere with Microtek. I have had a Scanmaker 4900 for about two years -=20 was working great. In the process of moving it to=20 another computer it was accidentally powered from=20 a 12 volt wall wart instead of the proper 12 volt=20 switching supply. The switcher is apparently=20 regulated, while the wall wart wasn't, and probably=20 went above 12 volts. Since then, even though connected to its proper power supply, the scanner has not produced its usual beautiful scans - they are washed out and get more so the longer the unit is turned ON, until after 2 minutes there is nothing.=20 Obviously something was zapped by the overvoltage. =20 Now Microtek wants a Lot of money ($80 to $100) to fix it - I can buy a new one for that amount. I asked=20 them for schematics so I could take a crack at it, but=20 no go - I was told it was too difficult to take the case apart without breaking it. Actually, I popped the case off in about 3 minutes - nothing broken. I informed them of that fact and was advised to call their professional consultants - at $30 per call. So here is the question - does anyone out there, by some=20 strange chance, have schematics for a Microtek 4900 scanner? Or even a close model 4800, 4850 ? I know the chance of this is very small, but I figure it can't hurt to ask.
