Image Scanner Modes

The 4820 is capable of working in single image scanner mode, multiple image scanner mode, or with Bluetooth devices, other than the 2020 base.

Unlinking the Image Scanner

If the base has an image scanner linked to it, that image scanner must be unlinked before a new image scanner can be linked. Once the previous image scanner is unlinked, it will no longer communicate with the base. To unlink an image scanner from the base, scan the Unlink Image Scanner bar code below.
