Ricoh MP 3010, print out blur on the text font, but negative print no blur...
Dismantled the PCU, found no uneven developer on magnetic roller...
Developer material not good? Other brand developer can be use?

Anyhow, swapped developer unit PCU A to PCU B and vice versa, both PCU ok...So strange?
But put back the original PCU drum unit & developer, problem come back...
Is there any setting need to be done for swapping developer unit?
