Hello fellow audio enthusiasts. I did purchase the cartridge brand new from the Needle Doctor. The box and other instructions are packed away in the basement. I did receive a reply from Lyra, and yes it is Washi paper used as a dust cover for the underside of the cartridge. It is NOT to be removed. And yes, it seems to pick up dust on its own due to (my best guess) static charges between the LP. (this is a low riding cartridge by design.) If I elect, Lyra will send the cartridge back to Japan and have new paper installed. I am going to take a much closer look under magnification and with a mirror later. Moonglum may be on to something. I'll post back with any new discoveries. I may also try some tweezers.....still debating this approach.
