Troubleshooting Tips
- Replace Drum warning: Your printer will display a Replace Drum message when the DR-720 nears end of life.
- Repeating marks on the page: Spots that recur at fixed intervals usually indicate a drum that needs replacement.
- Faded or streaky prints: Try swapping in a fresh TN-750 or TN-780 toner first; if quality does not improve, replace the DR-720 drum.
- Drum reset: Always reset the drum counter after installing a new DR-720 so the printer reports correct drum life.
