Replacing the drum cartridge When the imaging drum needs to be replaced, the REPLACE THE DRUM CARTRIDGE message appears in the copy module touch panel display. The copy module is still able to produce copies with this message displayed. However, copy and print quality may begin to degrade. Hewlett-Packard recommends replacing the drum when the message appears.
