4. Use the

Threshold

slider to change the threshold value,

monitoring the results of your changes in the Preview

window. Adjusting the threshold value can make it easier for

OCR to recognize characters.

If you still have problems...

1. In the EPSON TWAIN Pro window, increase the Resolution

value to 400. Remember that scanning at higher resolution

takes longer and may not greatly increase the recognition rate.

2. If you still have problems, try using the enhancement tools in

your OCR software to make adjustments.
