OMR Sheet Scanners
The type of OMR scanner you use will depend on the OMR sheets you have to scan. If they are plain paper OMR sheets, they can be scanned with a regular scanner and read using OMR software on your pc computer or laptop. If they are specially printed OMR Reader sheets, they will need to be scanned with the OMR reader scanner they compatible with.

How to Scan OMR Software Sheets
OMR sheets are scanned with a regular scanner that can procuce clear images.
Clearly scanned omr sheets, avoid errors which can occur with the detection of filled checkbox bubbles and barcodes.
A dedicated scanner for scanning OMR sheets is recomended so that scanned OMR sheet images are consistant quality that can be read by the OMR software you use.
A scanner with an automatic paper feeding tray is good for fast, OMR sheet scanning when you have hundreds of forms to scan and process.
Keep in mind an overloaded feeding tray can cause errors such as double feeding.
If the paper guides in the OMR scanner are too tight for the paper size, adjust them to make for smoother error free scanning.
If your OMR sheet scans can’t be detected by OMR software, the scanner’s dpi resolution should be adjusted to produce a clear wnough image that isn’t too large.
Images taken with a high dpi (more than 400dpi) are larger and will take longer to process by OMR software.
Regularly clean the scan head as trapped debris can cause streaks to appear on the scanned images.
OMR sheets must be compatible with the omr software being used, usually by way of a barcode type.
A TWAIN compliant scanner will connect to the OMR scanning software for one click scanning, and automatically produce the correct type of image that the OMR scanning software needs.
If you don’t have a TWAIN compliant scanner, you will need to manually set up the scanner to capture the correct scan and save it as the correct file type for the OMR scanning software.
Check the OMR scanning software specifications to determine the type of scanned image files the OMR software will recognize.
