The Check Scanner needs to be configured as an option on the Devices tab.
All registers that connect to the MICR readers must be configured to use the device when an electronic check tender type is used.
The receipt can be configured to control the number of copies printed with the e-check tender type. The default is one receipt, but this can be overridden so that two will print.
To Configure the Register Device for MICR:
Access the store level location for the device: POS Back Office > Locations > [name] > Registers > Edit Register > Devices tab

Right-click, select New and select the Check Scanner/MICR reader to be enabled.
Configure any additional registers as needed.
Note
Receipt configuration is handled via an InfoScript.
