Two pair or (4) Drum imaging unit reset chips/fuses for  Xante Ilumina Digital Press 427.  If the drum shows no signs of wear such as smudges why not just reuse the drum and reset the counter?  Most drums can be re-used up to 2-3 times before a need to replace it.  Our chip fuse will reset your counter.
