Do I need to replace the drum units when I replace the MFC-L3720CDW cartridges?

It depends on the number of pages you print with the drum unit rather than the replacement of toner cartridges. A drum unit is commonly more durable than a toner cartridge. That’s why Brother designed the toner cartridge and drum unit as separate parts to reduce waste. In most cases, you will need to replace the drum after the use of several cartridges. You can estimate when to prepare a new drum unit based on the page yield of the toner cartridge and drum unit:

  • TN229BK:1,500 pages
  • TN229C/M/Y: 1,200 pages
  • TN229XLBK: 3,000 pages
  • TN229XLC/M/Y: 2,300 pages
  • DR229CL: 3,0000 pages per unit

As you can see, the DR229CL lasts at least ten times longer than the cartridge. So, you might need to replace the DR229CL after using ten or more Brother MFC-L3720CDW cartridges. Rest assured that your printer will notify you when the drum unit needs replacing.
