[info.curtzsolutions]

I have a canon c5030 it was working alright untill the Bk started fading.thought it was the Toner i was using .so i manage till all runs out and i bought a new original Toner.But still the same fading persist.Now the Original has also finish yet the fading keep fading now,so it worse more than ever .I even swap the inner unit into a different machine ,it printed will but when I do return it back it fades.Things I have change.All HVT 1,2,3,PRINTER PCB 1,2 ,change laser units ,ITB unit,DC BOARD.when u print test 10 u could see YMC nice and solid but only black very light now
