Hello. I installed the repair kit MK-715 in Kyocera 4050. After switching on the copier shows code SC 7410. It turned out that the machine had drum unit DK - 716 installed, and the repair kit had a drum unit DK - 715 . Can I use the drum unit DK - 715 instead of the drum unit DK - 716? If so, what do i need to do? thanks
