The benefits of using Optical Mark Read (OMR) include higher accuracy, greater speed, and ease of use.
Higher Accuracy
- DataCap digital read head technology prevents undetected degradation of read head accuracy. Users are alerted when paper dust, erasure bits, etc., begin to build up and block read cells, or when read cells degrade or fail.
- Two light sources for each read cell minimize the effect of folds and wrinkles in documents.
- Precisely positioned read head wiping surfaces flatten wrinkled and folded documents and automatically clean the read head.
- Sixteen-level mark discrimination differentiates erasures and smudges from valid marks.
- Sheet thickness detector assures sheets are read one at a time.
- Sheet skew detection assures proper registration while reading.
Greater Speed
- Data transmission occurs as each row is scanned.
- Pearson Canada Solutions uses proprietary data compression technology.
Easy to Use
- An open feed path provides sheet visibility at all times, as well as easy access for sheet removal and transport cleaning.
- Scanner self-diagnostics quickly pinpoint problems.
