Hello everyone I have a problem with on a kyocera M6026cdn, using a compatible toner toner, after a few copies, he started begging to make strips and abut toner, when i opened the development group and i noticed they were cracking Of crystallized toners and then I emptied the development team, I put it back, I installed an original toner but when I start the multifunction I get the C7402 error. Any one of you can help me?
Thank you in advance

Never use compatible toner in a color machine. I'd guess you'll need new DV units & some OEM toner.

agree with Tmaged

What do you mean by 'emptied the development team'. At minimum your cyan developer is wrecked...

"C7402 Developer C Type Mismatch Error",
Ill guess that some sort of damage occured to an electrical connector for the Cyan DV, or maybe the prom on the DV got zapped by static.
