Answer sheet scanning
Answer booklet scanning, without cutting the spine
AutogradeX scans bound answer booklets page by page as the operator turns them. It works with a phone, a USB document camera on a laptop, or an existing overhead or book scanner, so colleges and exam centres can scan locally instead of sending every bundle to one central scanning hub.

Which devices can scan answer booklets for AutogradeX?
Three kinds of device work, and a programme can mix them. Each one ends in the same place: scanned pages attached to the right booklet, checked, and ready for evaluation.
| Device | How it works | Best for |
|---|---|---|
| USB document camera on a laptop | The camera sits on a stand; AutogradeX captures each page as it is turned and checks it on the spot | College and exam-centre scanning desks |
| Overhead or book scanner | The scanner's own software saves a PDF per booklet; AutogradeX picks up the folder and matches files by barcode | Hubs that already own overhead scanners |
| Phone on a stand | The same page-turn capture as the document camera, from the phone's camera | Backup stations and single-page rescans |
| PDF or images | Upload a PDF or page images in the browser | Booklets scanned elsewhere |
How does page-turn scanning work?
The operator opens the booklet under the camera and turns pages. AutogradeX watches the live picture, waits until the page is still, and takes the picture itself. Nobody presses a button for each page.
- Finds the page edges and corrects perspective and the curve of a bound page.
- Evens out shadows so handwriting stays readable.
- Reads the QR code on the cover and opens the right booklet automatically.
- Reads the printed page number on each page, so a skipped or repeated page is caught.
- Flags glare, a finger on the page, a cut-off edge, blur, a blank page or a duplicate the moment it happens.
Can colleges scan at the exam centre instead of a central hub?
Yes. An exam centre can register booklets from their cover QR codes and scan them the same day. The hub can require each scanning device to be approved before it uploads, and each station is calibrated with an A4 page to check resolution, light, glare, focus and steadiness. The hub sees each centre's progress and the pages scanned by each operator.
When the paper booklets later arrive at the hub in their sealed bundle, they are linked to the scans already made rather than registered twice.
What happens when the internet connection drops?
Scanning continues. Pages wait on the device and upload automatically when the connection returns, so an unreliable link at a college does not stop the scanning desk.
How is scan quality checked before evaluation?
Every booklet passes quality control before any evaluator sees it. QC staff see each page with the warnings raised during capture, can approve the booklet, or send it back for specific pages to be captured again. If a stored page image is ever lost, it can be restored from the booklet's earlier PDF without taking the booklet away from its evaluators.
Frequently asked questions
Do answer booklets have to be cut or unstapled for scanning?
No. Page-turn capture with a document camera, a phone or an overhead scanner works on bound booklets. Sheet-feed scanners are faster but need the spine cut or the staples removed, which many universities do not allow.
What resolution is enough to read handwritten answers?
Around 200 dpi is a common standard for handwriting. A 13 MP document camera over an open A4 booklet gives roughly 250 dpi per page. AutogradeX's station calibration measures the real resolution of each device.
How fast is scanning with a document camera?
The operator only turns pages, so speed depends on the booklet. As a rough guide, a 32-page booklet takes one to one and a half minutes including handling. Measure your own rate in a short pilot before planning stations.
