If the creaking or heavy sound returns, it's likely that the drum unit needs to be replaced. Contact a technician: If you're not comfortable replacing the drum unit yourself, or if the issue persists after replacing the drum unit, you should contact a qualified technician for further assistance.

Please rate me :)

First, what kind of technical background do you have? Also when replacing the drum you should replace the drum blade. Most of the drum/blade kits do not come with padding powder anymore so you will need the padding powder also -- if you do not use the padding powder you will get drum blade jitter and trash the brand new drum!!!!

TO replace the drum you will need to remove the toner cart., 1-2 covers, the dev. unit (developer) and then the drum unit. You will then have to take the drum unit apart to remove the old drum and blade. *****NOTE***** DO NOT TOUCH THE DRUM SURFACE OR THE MYLAR (RUBBER PART) OF THE BLADE WITH YOUR SKIN!!!!!! The oil from your skin will damage the drum and could damage the blade, again -- then they would be trashed.

I would spend the money to have a trainer tech. come out and replace/ rebuild your photo conductive unit for you. It would be money well spent.
