Intellifax 4100

A fax machine earns its keep when it never misses a page, and the Brother Intellifax 4100 is built around that job. Its main toner is the high-yield TN460, with the standard-yield TN430 as the smaller alternative for quiet lines. Both cartridges work with the separate DR400 drum unit, which forms the image for every incoming fax and copy while the toner is swapped around it on a much shorter cycle.

Fax traffic is unpredictable — a slow week can end with a thirty-page transmission at 4 p.m. That pattern rewards capacity over thrift: running dry mid-fax means lost pages and an apologetic phone call to the sender. Offices that depend on this machine for orders, referrals or signed documents usually treat the high-yield cartridge as the default and keep the standard-yield size as shelf insurance rather than the other way around.

Which cartridge should you buy?

For a working fax line, the TN460 is the sensible default: its 6,000-page genuine rating doubles the 3,000 pages of the TN430, so the cartridge lasts through long transmissions and copy jobs without constant checking. This page carries the compatible premium TN460 in single, 2 pack and 4 pack sizes, alongside genuine Brother TN430 and TN460 cartridges. A home-office 4100 that sends a handful of faxes a week can run the standard-yield cartridge and never feel the difference. The DR400 drum is a separate, slower decision — the genuine unit is rated for 20,000 pages. All compatible cartridges here include a 1-year warranty and 1-year returns.

Chip, toner and everyday use

Because a fax machine prints unattended, a spare cartridge stored next to it is worth more than a spare in a warehouse: whoever finds the toner warning can swap the cartridge in a minute and the line stays open. When output first fades, slide the cartridge out and tilt it gently a few times to level the remaining toner — enough to finish the day comfortably. Keep the drum unit covered when it is out of the machine and never touch its surface with bare fingers; skin oil prints through as marks on every page afterward.

Frequently Asked Questions

Which toner cartridge does the Intellifax 4100 take?

The high-yield TN460 is the main cartridge, and the standard-yield TN430 fits the same slot as a smaller option. The genuine versions are rated for 6,000 and 3,000 pages respectively, and both are stocked on this page along with compatible premium TN460 cartridges.

Does the Intellifax 4100 use a separate drum unit?

Yes — the DR400. It is a standalone part that the toner cartridge seats into, and it is replaced on its own schedule rather than with every cartridge. The genuine DR400 is rated for 20,000 pages.

My received faxes are printing light. Is it the toner or the drum?

Evenly light pages usually mean the toner is running low. Streaks, repeating spots or smudged backgrounds that stay in the same place point at the DR400 drum instead. Try a fresh cartridge first; if the marks survive the swap, the drum is due.

How many toner cartridges does one drum last through?

On ratings alone, the 20,000-page genuine drum covers roughly three high-yield TN460 cartridges or six standard-yield TN430 cartridges. Real life varies with page coverage, but the drum is always the long-interval part of the pair.
