Ultra-High-Speed Production OMR
SR-11000
11,000 sheets/hour — The World's Fastest Desktop OMR Scanner for National & Central University Exams
The Sekonic SR-11000 represents the pinnacle of Japanese optical engineering in automated exam grading. Rated as the fastest desktop Optical Mark Reader (OMR) in the world at 11,000 A4 sheets per hour, it is purpose-built for central university control rooms, national testing centers, and ministries of education handling tens of thousands of answer sheets under tight deadlines.
Key Engineering Capabilities
- Blazing throughput of up to 11,000 sheets/hour with simultaneous single-pass duplex (double-sided) optical reading.
- 500-sheet high-capacity automatic hopper paired with Dual Output Stackers (Main + Select Reject Stacker) to automatically out-sort blank, improperly marked, or double-fed sheets without stopping batch processing.
- Ultrasonic double-feed detection sensor preventing overlapping sheets from ever going unnoticed.
- 256 levels of optical mark density recognition—reliably distinguishing intentional pencil/ballpoint marks from erased smudges or stray marks.
- 1D/2D barcode reading for encrypted student IDs plus an optional inline inkjet imprinter for real-time serial numbering and audit trails.
- 100% authentic Japanese heavy-duty metal chassis engineered for millions of exam sheets across decades of continuous academic service.
