Lexmark iMFP: Scan to Email produces an EDI Error "The method 'B' is not implemented."

Symptom:

When scanning using the Lexmark eDas iMFP solution I see the below error in the eDas log and the EDI log on the Uniprint server.

20150911 11:22:40.019 ERROR   #104pharos - T|pharos|unhndlFlt|S|NotImplemented|S|The method 'B' is not implemented.

20150911 11:22:40.028 ERROR   #0 System Bundle - [stderr] com.lexmark.es.pharos.PharosError

Resolution:

Please open the registry on the EDI Server the Terminal communicates to and create the following key under the "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Pharos\Edi" key.

Create a new String Value called "Enable Retired Calls" and set the value to "7.2"

You will need to restart IIS (iisreset from a administrative command prompt or using the IIS console in Windows). This will correct the error you are seeing. The Lexmark eDas iMFP solution uses legacy EDI calls that have to be enabled in the registry.
