my canoscan 4200f scanned documents are entirely black.

[SDeGroff]

I have unplugged and replugged scanner, restarted computer, uninstalled and re-installed driver and same result: documents are all-black. The lamp on the scanner appears to be working. It is bright when scanning.

Hi SDeGroff,

Performing a few calibrations should clear up the issue that you are experiencing. Please follow these steps to perform a calibration:

 1.  Click the [Start] menu and select [(All) Programs], [Canon], [CanoScan Toolbox] and then [CanoScan Toolbox].

 2.  Click the SAVE.

 3.  Place a checkmark in "Use the Scanner Driver to Make Advanced Settings".

 4.  Click Apply.

 5.  Click Scan.

 6.  When Scangear appears, click the Settings tab at the top right side.

 7.  Click the Calibration button.

Perform 3 or 4 calibrations and then attempt to scan again.
