I wonder if you use is original drum unit, or homemade drum unit.
If you are using is homemade drum unit, then after 12 a se drum plus powder light magnetic roller spring may be broken or not good contact with the conductive iron drum cover, there may be no good charging and charging roller carbon powder quality has a problem.
If encounter after 12 a se drum plus powder light, first look at the magnetic roller spring had broken and carbon powder if you have any questions, are the two causes.
If the spring did not break contact with the conductive plate is good, and carbon powder and no quality problem, then you will be a little bit of conductive charging roller ends and conductive paste to try again.
