Solution: Lexmark Document Distributor

Issue Description:
The following Lexmark document distributor ( LDD) script line for a Scan to E-mail workflow is used for producing a 1-bit monochrome scan file for Lexmark products before 2016:
scprompt.setDeviceParm("contentType", ScanPrompt.TEXT_MODE);
However, using the same script on 2016Lexmark products will produce an 8-bit monochrome image scan.
Explanation:
The reason for this is that additional functionality was added to the 2016 Lexmark products; therefore, the current behavior is FAD (functioning as designed).
However, the new functionality prevents inferring a bit depth setting the same way as previous product generations.
This change will be reflected in the next revision of the software development kit ( SDK) documentation.
Recommendation:
For the Lexmark 2016 products, the following LDD script needs to be used, which will explicitly set the mono bit depth to 1 in order to get a 1-bit scan:
scprompt.setDeviceParm("monoBitdepth","1");
