I changed the developer, drum, drum cleaning blade and corona wires. 2-questions.
#1 i ran the procedure for new developer is there one for new drum???
#2 what would cause off-setting after about 3 copies??? only notice it at the last 1/4 of page on one side of copy; i believe side closest to front of copier(11x8.5 direction). remember new drum and cleaning blade installed. can not tell you if it was doing this before i serviced copier.
thanks!!!

Developer setup does the drum and dev setup on this model. Did you reset the counters in pm support mode? Did you use setting powder on the drum? if not then the blade may have flipped. Also check the fuser roller for buildup.
