The "replace drum soon" indicater is a warning for you to have a new replacement drum "on-hand". Soon the display will change to "REPLACE DRUM" AT WHICH TIME THE UNIT WILL STOP PRINTING.
When the new drum cartridge is then installed...the REPLACE DRUM indicator will be reset. DO NOT replace the drum before the machine says to.
