The following types of originals may make it hard to recognize characters. Text in originals needs to be clearly typed or printed.
Color text
Cursive, italic, or other design fonts
Text with a font size of 6 points or less, or 45 points or more
Text on a colored background or shaded text
Text on ruled lines or underlined text
Originals with complicated layouts

Handwritten text
Recognition accuracy may decline for originals that have a low contrast. To improve detection accuracy, try using the Text Enhancement function on the Scan screen or the Scan Settings screen.
If the original is rotated 90 or 180 degrees when it is scanned, the text in the original cannot be recognized. Use the Rotation function on the Scan screen or the Scan Settings screen, and then scan again, or rotate manually using the “Rotate” function in the “Image tools”.
If the text in the original is at an angle and not horizontal, it may not be recognized accurately. Use the Correct Skew function on the Scan screen or the Scan Settings screen, and then scan again, or manually correct skew using “Adjust Angle” in the “Image tools”.
Some items and settings may not be available depending on the scanner you are using.
