3.5 Use of Extension Plates on the ScanCheck 3
Transparent extension plates with various cut-out widths can be used as accessories for the REA
ScanCheck 3n. To do so, the standard-installed trapezoidal transparent base plate is removed and
replaced by one of the extension plates.

The use of extension plates is always recommended when labels or films must be pressed flat on the
underlay because otherwise the label material can wrinkle up.
They are indispensable if codes must be measured on round surfaces (e.g. barrels, cans, etc.). They
are also required if bar codes must be measured at positions or on articles with too small of a surface
for positioning the unit.
Attention:
Extension plates must always be removed for calibration.
