    Ricoh Aficio MP1900 (Similar MP1500, 1600) Dots on drum

    Changed drum, developer, customr is using toner OEM.

    Machine is back in 2 weeks, now the drum shows dots on one side.
    I'm wondering if the GND or MAIN HV could be the cause
    values are as per indicated in the factory adjs. log.

      Have you checked the charge roller for marks ?

          Toner is OEM. How about the Drum and Dev you replaced?

          Are these the same symptoms that had you replace the drum and dev in the first place?
