Scantron Test Scoring Machine
How accurate are scantron machines?
The Scantron 888P+ model can grade as many as 40 tests per minute with a 99.9% accuracy rate. Scantron forms contain an infrared light-reflecting ink. When a form passes under an internal read head, the machine notes where the light has been absorbed by pencil lead.

Each time you stop scanning you are creating a new batch file. These files are stored locally on the computer and will auto increment until they are finally uploaded.
