Dump the developer, clean the development roller (use a copper wire brush if necessary to fully remove the coating) and thoroughly remove all toner from the PCU to include the toner recycler. Replace the developer and toner. Use only Genuine Ricoh or NA Trading developer and toner unless you want the problem to return.
