[Running Windows Vista Home Premium]

I own a Canoscan LiDE 200, and have been having some problems. Firstly when trying to use the scan button on the scanner's front, using either ScanGear Starter or MP Navigator EX an error reads saying;

'Release the lock switch, detach the USB cable and reconnect. Scanner driver will be closed'

When I try doing this it still doesn't work. I have managed to get the scanner working using ArcSoft PhotoStudio though.

The more serious problem though, is that my scans are coming out with streaks. When using the colour scan, alternating streaks light and darker in brightness appear across the scan. Ive tried removing the glass and cleaning it, and tried scanning without the glass bed at all, still scanning comes out with streaks.

The Streaks run vertically when the scanner is positioned in a portrait position, and are of various widths, and are not of a uniform pattern. Where the streaks occur the scanned image is lighter than the rest of the scan.

Does anyone have any advice about sorting this out? Would be Much Appreciated

Jon

As far as the streaks go, it's something internal.
It sounds like it could be either a bad / loose belt or a bad servo motor

OK, do you think I can sort any of this out myself by taking off the glass again, or will it have to be taken to a computer repair place?
thanks for your help

You would have to observe the lamp as it travels the bed for a smooth fluid motion but unless it's a slight misalignment or some type of obstruction, there isn't going to be much that you can do
