Installing the Toner Cartridge


  • Do not dispose of used toner cartridges in open flames. Also, do not store toner cartridges or paper in a location exposed to open flames. This may cause the toner to ignite, and result in burns or fire.
  • If you accidentally spill or scatter toner, carefully wipe up the loose toner with a damp, soft cloth and avoid inhaling any toner dust. Do not use a vacuum cleaner that is not equipped with safety measures to prevent dust explosions to clean up loose toner. Doing so may cause damage to the vacuum cleaner or result in a dust explosion due to static discharge.
  • Use caution not to inhale any toner. If you should inhale toner, consult a physician immediately.
  • Use caution so that toner does not get into your eyes or mouth. If toner should get into your eyes or mouth, immediately wash with cold water and consult a physician.
  • Use caution so that toner does not come into contact with your skin. If it should, wash with soap and cold water. If there is any irritation on your skin, consult a physician immediately.
  • Keep the toner cartridges and other consumables out of the reach of small children. If toner is ingested, consult a physician or poison control center immediately.
  • Do not disassemble or modify the toner cartridge. Doing so may cause the toner to scatter.
  • Remove the sealing tape of the toner cartridge completely without using excessive force. Doing otherwise may cause the toner to scatter.

Preparing Toner Cartridges
The machine comes with toner cartridges installed at the time of purchase. You must remove the sealing tape from the cartridges to use the machine.
1. Open the front cover.
2. Pull out the cartridge tray.
MF729Cdw / MF726Cdw
MF628Cw / MF624Cw
3. Remove the sealing tape by pulling it straight up while holding down the toner cartridge.
  • The full length of the sealing tape is approximately 19 3/4" (50 cm).
  • There is a toner cartridge for each of the four colors. Remove the sealing tape from each toner cartridge.
When pulling out the sealing tape
If the sealing tape remains inside the toner cartridge, the quality of printouts, including faxes, may deteriorate. Also note that it will not be possible to reprint a fax because the fax function automatically deletes data once it is printed.
  • Do not pull out the sealing tape at an angle. If the tape breaks, you may not be able to pull it out completely.
  • If the sealing tape becomes stuck when pulling it out, keep pulling until it is
completely removed.
4. Push the toner cartridge tray back in, and close the front cover.
  • Make sure that all four strips of sealing tape have been removed from the machine.
  • Dispose of the sealing tape according to local regulations.
