Happy Camper got me taken care of. Thanks a bunch!
I don't know if others have had this trouble or not, but on my VJ-1204, the rubber pressure rollers that hold down the media got soft and gummy and started to leave gooey black stuff on prints. Mutoh let me know the part number is DF-49053. I did a search and found a company in Belgium, Digiprint Supplies, that sells a set 68 of them (it takes 64 to replace them all) for about a dollar each when buying the lot. FedEx shipping to the States is under $25.00. Replacing those will be my first project with my service manual.
