Operation Manual
Contrast
When scanning low-quality documents, adjusting the Contrast level is sometimes required to obtain
an optimal scan result.
Move the Contrast slider to the right to increase the contrast between the background and the text.
Move it to the left to reduce the contrast.
Note: when the option Auto-exposure is selected, the Contrast slider is unavailable. The
contrast settings are then adjusted automatically.
Brightness
When you are scanning dark, blurry images, or extremely light images, it may be necessary to adjust
the Brightness settings.
Move the Brightness slider to the right to increase the brightness of your scans. Move the slider to
the left to reduce the brightness.
Note: when the option Auto-exposure is selected, the Brightness slider is unavailable. The
brightness settings are then adjusted automatically.
Optimize resolution for OCR
This option adjusts the resolution of images that were scanned with too much detail (over 600 dpi).
When this option is activated Readiris reduces the resolution to a suitable level.
Note that this option doesn't increase the resolution of images scanned with too little detail.
Scan another page after
This option is useful when you are scanning multiple pages on a flatbed scanner. It allows you to
determine after how many seconds Readiris scans another page. This way, you have the time to
change the pages on the scanner while Readiris scans them automatically. You no longer need to go
back to your Readiris application and click the Scan button every time you want to scan a new page.
Use the up and down arrows to determine after how many seconds you want Readiris to scan a new
page.
Format
Click the Format list to define the size of the documents you are scanning.
Tip: in the US Letter and Legal are the two most common formats. Internationally, A4 is the
standard.
Resolution
Select in which resolution you want to scan images. A resolution of 300 dpi (dots per inch) is
recommended. When you are scanning very small print or Asian languages, 400 dpi is
recommended.
