How to Clean a Laser Printer Drum without Removing it from the cartridge

Hello I have an hp colorlaserjet pro mgp m182n that uses hp 216a color toner cartridges . The problem I am facing is that whenever I replace drum of black cartridge , it's intensity of black in every print increases, slight outline of black comes around some words and whole page is kind of blackish. This happens with every new drum.
Can you kindly tell cause of this issue and how can that be solved?
