It affects Kofax Capture 11.1.0.0 and is resolved in Capture 11.1.0 Fix Pack 1. The standalone fix from https://knowledge.kofax.com/bundle/z-kb-articles-salesforce5/page/19774.html can also be installed.
Alternatively, the affected document/image can be reduced in size and reimported in order for conversion to succeed without having to upgrade or patch Kofax.
