      Did you replace the drum and EPU Kit at the same time. Charge loss will suck all the developer right out of your developing unit. =^..^=
      If you'd like a serious answer to your request:
      1) demonstrate that you've read the manual
      2) demonstrate that you made some attempt to fix it.
      3) if you're going to ask about jams include the jam code.
      4) if you're going to ask about an error code include the error code.
      5) You are the person onsite. Only you can make observations.

              This is an ongoing issue on the 5520/5540 series. From the 5520 series forward the dev has been modified 4 times. Problem is more prevelant in low color usage and or low humidity enviroments. Aside from checking all the things mentioned in previous replies, frequently setting the dev mag pole position to +2 helps or cures issue. I highly recomend doing all 4 devs simultaneously. Also I highly recomend using OEM dev if at all possible. These machines are extremely intolerant of sub par supplies.
