Functional problem sc 390 on ricoh photocopier, despite replacing drum, developer,blade,gears. after removing 9 copies it reads functional problem.


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.
