the squeak is coming from the drum unit. If you take out the drum and rotate it by hand it will most likely give you the same noise. you may be able to stop it by pouring some toner on it, but in reality it is more annoying than a problem.
there is a blade that scrapes off excess toner from the drum, it is slightly dry and causes the squeaking, technicians usually use a special powder that looks like baby powder to "lubricate" the blade, and stop the noise.
