Troubleshooting: Recognition

The music was scanned as RGB color.

Rescan using SmartScore’s scanning interface or with your scanner’s software making sure your settings are Grayscale (sometimes called "Document" or "Text") and not color or black&white (1-bit).
 
Open the .TIF file in Photoshop or some other image editing program, change "mode" or "bit depth" from color to Grayscale then resave the file as "Uncompressed" .TIF

The music was scanned at screen resolution (70 to 90 dpi) or too high (600+ dpi).

Open the .TIF file in SmartScore (it will automatically open in the Image Editor). Check the resolution (☰ VIEW > Image Information. See Image Information dialog box). Rescan if necessary.

The scan was upside-down or sideways.
 
The music contained front matter (cover, table of contents, etc.)

Use the tools in SmartScore’s Image Editor to rotate each page to the correct orientation and/or delete cover, front matter, table of contents and any other non-music material.
