Bzhub pro 1050 Print Issue or unprint issue

[dmtchm]

Need help with this plz. We have a bizhub pro 1050 that started printing light because of developer . It was due. We did the PM kit with developer and New Drum. after about 100,000 prints started printing light again after checking we had a developer unit way beyond its life and developer leaking out around shafts. replaced developing unit and new developer. Printed great about 14,000 sheets now have a unprinted streak down one side unused toner on drum and heavy on the charging unit. What did I do wrong ?? Any help appreciated.
