TIFF can use JPEG compression, so it is likely that the issue is with JPEG image handling even though it is a TIFF. But TwelveMonkeys also has an imageio-tiff component so you can try both. Get the source from github, build it (mvn clean install, I think) and place the needed jars in the FOP lib directory. The fop.xconf does not need to be modified.
