HL-5450DN
The supply math for the Brother HL-5450DN starts with one number: 3,000. That is the genuine rating of the standard-yield TN720, this machine's lighter toner. Its high-yield partner, the TN750, is rated at 8,000 genuine pages, and both cartridges drop into the same DR720 (DR-720) drum unit, itself rated at 30,000 pages in genuine form.
Run those three numbers together and the machine's appetite becomes predictable. One drum spans roughly ten standard cartridges, or about four high-yield ones, so a drum order is a rare event in this printer's life. Toner is the recurring purchase, and the only real question is the size of each refill. An owner who tracks cartridge changes can forecast the year: count last year's swaps, multiply by the yield that produced them, and the HL-5450DN's supply budget is written. This page stocks both yields in singles and multi-packs so the plan, once made, is easy to keep.

Which cartridge should you buy?
The 3,000-page TN720 suits measured, predictable output — a cartridge every few months, bought singly, with little money resting in the supply drawer. The TN750 changes the arithmetic for heavier use: 8,000 genuine-rated pages means fewer orders, fewer interruptions, and a lower cost attached to every page that comes out of the machine. Multi-packs deepen that effect where the printer is shared. The drum enters the basket only near its 30,000-page horizon; a toner-and-drum set then covers the one occasion when both consumables come due together. Genuine Brother cartridges are stocked at both yields alongside the compatible lines.
Chip, toner and everyday use
Treat the printed yield as a rating, not a promise: it is measured at roughly 5% page coverage, and real documents with dense text or graphics finish cartridges sooner. The cartridge chip estimates what remains, while the drum's counter keeps a separate tally, so the machine may ask for a drum while toner is still healthy. Rocking a fading cartridge gently from side to side evens out the toner and buys extra pages before the swap. Store the next cartridge sealed and flat, and keep a new drum dark and bagged until installation day.
Frequently Asked Questions
How many TN720 cartridges does one drum outlast?
At the genuine ratings, about ten: the DR720 is rated at 30,000 pages and each TN720 at 3,000. With high-yield cartridges the count is roughly four.
Does the high-yield cartridge really lower cost per page?
Yes. The TN750 carries 8,000 genuine-rated pages against the standard cartridge's 3,000, so its price is spread across far more printed pages.
Does the HL-5450DN take a special cartridge?
No. It uses the standard TN720 and TN750 codes shared across this cartridge family — the same listings serve every model in the list below.
Why did print fade before the toner warning?
Yield is rated at about 5% coverage, so dense pages can empty a cartridge ahead of its estimate. Rock the cartridge gently to redistribute toner; if fading persists with a fresh cartridge, check the drum's age.
