OMR Glossary
Column and Row
Mark frames are in columns, timing marks are in rows.
Jam
A sheet jam error caused by media when the sheet is being fed.
There are two kinds of jams: static jams detected when the device is at rest, and operational jams
detected while the device is running.
Operational jams include double-feeding jams and no-feeding jams.
Skew
Refers to the sheet that is slanted against the sheet feeding standard.
This function detects whether or not the sheet is fed straight.
Perforated sheet, sheet unevenly cut, and curled or bent sheet is likely cause skew errors.
Stacker
This refers to the place that sheets that have been read are temporarily stacked. Stacker volume
refers to the number of sheets that can be accommodated. Example: stacker volume 200
sheets.
