NSIGHT 4ES Scanners
Schedule
In general, it is best to clean your scanner once a
month. However, you may need to clean your
scanner’s read heads more frequently depending on
the following:
•
Scanner operation - A scanner operating in OMR w
Imaging mode (optional) may need to be cleaned
more often than a scanner operating in OMR Only
mode.
•
Paper dust - Sheets that generate more paper dust
will necessitate more frequent cleaning. Perforated
sheets generate a considerable amount of paper
dust.
•
Read head contamination - Eraser fragments and
white out, if used, can build up on the read head.
