I have 14 kyocera Fs-9530DN printers. One of them is giving Call Service 5300:2150259. I have changed drum unit as i suggested in manual but it is still there. Some times it works alright but then it gives this error again. I have also changed the electronic board of drum unit(which has 4 springs) at rear side with other printer but it doesn't work. I have also checked the connection which is coming from main board.
I have done everything that i can do but I am stuck. kindly suggest any solution.
