While I was installing a set of new CMYK cartridges I made a mistake and accidentally touched the drum of the K cartridge. Whether it was this mistake or a defective cartridge (ti was an off brand) now the when printing black the text on the left half of the page black is barely visible. The fading is uniform from top to bottom of the page.

Is it ever possible to clean the drum or am I stuck with buying a new K cartridge?
