What Is the Difference Between TN630 and TN660?

Cartridge Yield class Approx. pages (5% coverage)
TN630 Standard ~1,200 pages
TN660 High yield ~2,600 pages

They are the same size and fully interchangeable. TN660 costs less per page, so it's the better buy for most offices.

Do I Need a Drum Unit With TN660?

Yes, but not every time. The TN660 toner snaps into a separate DR630 drum unit, which lasts about 12,000 pages, or four to five high-yield toners. Replace the drum only when the printer shows "Replace Drum" or prints start showing repeating marks. Move the drum from the old toner to the new one each time.

How Do I Install a TN660 Toner Cartridge?

  1. Open the front cover and pull out the drum and toner assembly.
  2. Press the green lock lever on the drum and lift out the old toner.
  3. Gently rock the new TN660 side to side a few times to spread the toner, then remove its protective cover.
  4. Push it into the drum until it clicks. The green lever lifts automatically.
  5. Clean the corona wire by sliding the green tab on the drum left and right a few times, then return it to its home position.
  6. Reinsert the assembly and close the cover.

Why Does My Brother Printer Still Say "Replace Toner" With a New TN660?

Brother L2300-series printers use a small gear and sensor to detect a new cartridge. If the message persists, reseat the toner in the drum firmly, and make sure you removed all packaging. Our guide on how to reset a Brother toner cartridge covers the menu reset and the "continue" setting.

Frequently Asked Questions

Is TN660 compatible with the HL-L2350DW?

No. The HL-L2350DW and other L2350/L2370/L2390-series printers use TN760 / TN730 toner and the DR730 drum.

How many pages does a TN660 really print?

About 2,600 pages at 5% coverage, which is typical text. Pages with heavy graphics or large solid areas reduce the count.

Can I use a compatible TN660 without voiding my warranty?

In the US, the Magnuson-Moss Warranty Act means a manufacturer can’t void your printer warranty simply because you used a third-party cartridge. They can only deny coverage for damage the cartridge actually caused.
