Instructions to reset the Brother DR-2400 image drum counter
The Brother DR-20400 page yield (LIFE) is set and is controlled by your printer. The printer controls the number of pages you can print using your drum by counting how many times the image drum rotates (pages printed) and stopping the drum at the set page yield. Your printer will shut the drum unit down when it reaches a max page yield of 12,000 pages (measured at only 5% text coverage). You will then have a “replace drum, or drum life end” warning message or series of error lights and you will be unable to print.
At this point most DR-2400 image drums can actually be reset for another cycle.
The exact procedure for resetting the DR-2400 image drum will depend on which model number Brother printer you have.
