What it means
On the ECOSYS M2030dn, M2035dn, M2530dn and M2535dn, Kyocera explains that Replace MK means the parts in the maintenance kit must be replaced at every 100,000 pages of printing, and that this requires professional servicing. MK stands for maintenance kit. The message is based on the page count, not on a part having failed: it is scheduled maintenance. The guide does not treat it as an owner task, which is why it refers you to a service technician.
