    Di 470 MINOLTA

    Hi,
    TWO MONTHS AGO I REPLACE DRUM,BLADE AND DEVELOPER IN THE Di 470 COPIER, AFTER MAKING 10000 COPIES I GET COPY WITH BACK GROUND LIKE BOIS BROBLUM, I CHECKED EVERY THING BUT VAIN,THEN I PUT THE OLD DRUM IN THE COPIER IT WORKS GOOD,
    THEN I TRY THE NEW DRUM AN OTHER COPIER THERE ALSO I GET THE SAME RESULT WITH DARK BACK GROUND,THIS A OPC DRUM I CHANGE THE VG VALUE AND ATDC ,REFINE ,BUT STILL WITH DARK BACK GROUND. SO I NEED ANY SUGGESTION ?

    Sounds like it is overtoning! Set the toner level lower (can't remember how-sorry!) and run some skyshots to drop the toner level to what you like. Then redo the ATDC setup. Maybe clean the AIDC sensor too - F5?

    Hope this helps.

        OK... Have you checked the drum earth? Also, the bias pin on the mag roller (check contact in machine body is clean and check pin for wear).. I still think it might be overtoning. What are the heavy solids like?

          Where did you get the new drum? Is it a real Minolta drum or an after market drum? You might try increasing the charge voltage and/or the bias voltage for the background.
