Sekonic SR3500 H OMR Scanner
The Sekonic SR-3500 is an Optical Mark Reader (OMR) scanner that can process up to 3,500 documents per hour. It's designed to accurately scan OMR forms for pencil and pen marks, bar codes, and can also capture full-page images.
Efficient & Reliable Mark Reading:
Equipped with cutting-edge OMR technology, the SR‑3500 reads pencil and pen marks (bubble, X, check) with near-perfect accuracy. Its 256-level density sensing and skew correction mechanism virtually eliminate misreads, ideal for high-stakes testing or survey collection.
Key Features:
High Throughput – Scans up to 3,500 sheets per hour (≈60 ppm), making it efficient for bulk processing.
Large Hopper Capacity – Holds up to 500 sheets, reducing manual loading time.
Ultra-Accurate Mark Detection – 256-level density detection (16-step threshold) ensures reliable recognition, even of light or hand-drawn marks.
Feed & Jam Prevention – Detects and prevents double-feeds, misfeeds, and skews for consistent results.
Flexible Connectivity – USB 2.0 and RS-232C interfaces support easy integration with PCs or existing legacy systems.
Intuitive Control Panel – 40-character LCD with navigation buttons allows convenient status monitoring and settings without needing a computer.
Modular Expansion Options – Add-ons such as duplex (double-sided) scanning, barcode reader, inkjet printer, and select stacker enhance capability.
Global Compliance – Meets worldwide standards (FCC, UL, CE, RoHS, etc.), suitable for use in diverse regions.
Expandable and Customizable Workflow:
Base model handles A4/Letter/Legal forms via the ADF. Optional modules like duplex scanning, barcode reader, inkjet printer, and select stacker (which preserves page order), let you tailor the device to specific data-collection needs, such as barcode-tagged forms or timestamp printing.
Hybrid Imaging Model Available:
Upgraded SR‑3500 Hybrid includes dual sensors: an OMR sensor plus a contact image sensor. It captures both mark data and full-page images (up to 300 dpi, B&W, grayscale, or color) in a single pass, ideal for capturing handwritten responses alongside bubble data.
User-Friendly & Easy Maintenance:
Features like automatic calibration, built-in self-tests, top-open feeder for clearing jams, and selectable stacker options make it easy to operate and maintain. The intuitive LCD display and button panel offer status updates and quick diagnostics.
