TCT TN635C Cyan Toner Cartridge

The TCT TN635C is a new, standard-yield cyan toner cartridge built as a compatible replacement for the Brother TN635C. It is intended for owners of the HL-L8430CDW, HL-L8430CDWT, HL-L8570CDW, MFC-L8730CDW, MFC-L8930CDW, or MFC-L8970CDW who need a single colour refill.

Replaces Brother TN635C

This cartridge directly replaces the Brother TN635C original equipment cartridge. The jump is worth it when you want a lower-cost cyan supply that still delivers sharp text and smooth graphics for reports, invoices, and business documents. It is not for buyers who need a high-yield cartridge or a multi-colour pack.

1800-page standard yield

Each unit prints approximately 1800 pages at 5% coverage on Letter or A4 paper. That capacity comfortably handles everyday office printing and schoolwork. It runs out faster in high-volume environments or when printing graphics-heavy pages that exceed the standard coverage baseline.

Questions about this item

Which printer models accept the TN635C cyan cartridge?

The cartridge fits the HL-L8430CDW, HL-L8430CDWT, HL-L8570CDW, MFC-L8730CDW, MFC-L8930CDW and MFC-L8970CDW printers.

What is the correct way to install the cartridge and what step is often missed?

Open the front cover, remove the old cartridge, unpack the new TN635C, gently rock it side-to-side to distribute toner, pull the sealing tape straight out, then slide the cartridge in until it clicks.

When will the TN635C need to be replaced and what indicates it?

Replace it after roughly 1800 pages at 5% coverage; the printer will show a low-toner warning and print quality will fade.
