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 2016 Lexmark products will produce an 8-bit monochrome image scan.
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.
