Toner supply defective

* Insufficient toner in developing unit

SC 390 is a TD sensor code try changing developer (Type 24) B0649645 if not that then maybe the TD sensor pn#B2475310,

SC 390 on an Aficio 1018 will most likely be a bad TD (toner density) sensor, if you've already replaced the drum and developer. (One thing to check quickly though is to pull the PCU out and reinstall it, just to make sure that connection isn't the problem.)

You can either replace the TD sensor by itself, or replace the DV unit (which probably won't be much more expensive). But either way, you'll need to install new developer when you replace the parts.

high voltage supply board defective

That denotes a defective TD sensor. The sensor may need replacing and the developer will need to replaced and initialized with it.

SC 390 TD sensor error

The TD sensor outputs less than 0.5V

or more than 4.0V 10 times

consecutively during copying.

• TD sensor abnormal

Poor connection of the PCU

You most likely have a defective "yellow" PCU . Try replacing that.
Otherwise you have a high voltage problem
