p errors on KM

[tou.yang]

I have these errors on a KM c454e. I already replaced the idc sensor/bracket and the errors did not change. A few weeks ago, i replaced all the drums and dev with good used ones from another machine because it was ghosting. Let me know what you guys recommend next. Thanks in advance.

Gotta replace with new parts or the P codes wont go away.

By the look of those codes, it may have emptied one or more of the new (old) developer units as this line sometime does when playing with used parts/supplies.
