Troubleshooting
Reboot the computer, lower the Output Resolution and rescan.
Reset and reboot the computer, delete unnecessary files and application
programs, and rescan.
Open ScanGear MP from within the application program, click the [Preferences]
button in the Advanced Mode, and change the folder listed in the [Select Folder
Where Temporary Files are Saved] category to one on a disk with sufficient free
space.
Disconnect all other devices but the machine from the port.
Rescan with adjusted settings. (See the Scan Guide)
Some application program does not display the image clearly if the image is too
small. Set the view mode to 100%.
Select [Magazine (Color)] for Select Source in the Simple Mode or turn on the
[Descreen] option in the Advanced Mode of ScanGear MP. Turn off the [Unsharp
Mask] function if the moiré effect is still too strong even when the Descreen option
is on. (See the Scan Guide)
Set your display settings on your computer to Medium (16 bit) or higher.
In the [System Preferences] dialog, click the [Displays] icon and select the
[Display] tab. Set the [Colors] list box to [Thousands] or a higher setting.
Clean the Platen Glass or the Document Cover of the machine, taking special care
not to press strongly on the Platen Glass.
Scan with certain functions such as Remove Dust and Scratches, Fading
Correction or Grain Correction in the Image Settings section of the Advanced
Mode of ScanGear MP.
Note
If a print out of an image does not appear satisfactory or the same as what you see
on the monitor, you may need to change the machine's settings, or the machine
itself may have engaged in problems.
Specify the scan area appropriately.
If you click the Auto crop button of the ScanGear MP, the scan area is adjusted
autmatically to match the size of the original. When scanning an original
surrounded by white borders such as a photo print, of if you otherwise want to
specify a custom scan area, specify the scan area manually. Refer to the Scan
Guide for details on manual scan area specification.
