This is the big-screen member of its colour family: a 7-inch display fronts a full print, copy, scan and fax all-in-one printing at 33 pages per minute.

First, the Question This Model Always Raises

Most Brother colour printers in this range stop at three toner tiers. This one adds a fourth on Brother's own shelf: TN437, rated around 9,000 pages black and 8,000 per colour. Shoppers sometimes assume a compatible equivalent must exist.

It does not — not from us. Our store search returns no compatible TN437, so plan running costs around TN436, the ceiling for compatible savings.

Ratings for the Three Compatible Tiers

Figures are Brother's, to ISO/IEC 19798; dense colour pages shorten any cartridge's life versus these ratings.

Supply tier	Black	Cyan	Magenta	Yellow
TN431 — standard	~3,000 pages	~1,800 pages	~1,800 pages	~1,800 pages
TN433 — high	~4,500 pages	~4,000 pages	~4,000 pages	~4,000 pages
TN436 — super high	~6,500 pages	~6,500 pages	~6,500 pages	~6,500 pages

From the carton, it ships with standard supplies — black near 3,000 pages, colours near 1,800 each.

Each Colour Has Its Own Page

TN431 position: TN431BK Black · TN431C Cyan · TN431M Magenta · TN431Y Yellow

TN433 high yield: TN433BK Black · TN433C Cyan · TN433M Magenta · TN433Y Yellow

TN436 super high yield: TN436BK Black · TN436C Cyan · TN436M Magenta · TN436Y Yellow

Transparency on the first row: the TN431-slot listing is built on a shared TN431/TN433 high-yield design, rated 4,500 pages black and 4,000 per colour at $28.39. No distinct lower-rated compatible TN431 exists, so read it as a high-yield cartridge in the standard slot.

Cost Per Page, Tier by Tier

• TN433 black: $28.39 across 4,500 pages — about 0.63 cents per page. TN433 colours: $28.39 across 4,000 pages — roughly 0.71 cents.
• TN436 black: $27.55 across 6,500 pages — about 0.42 cents per page. TN436 colours: $29.46 across 6,500 pages — roughly 0.45 cents.

Brother recommends up to 4,000 pages monthly for this machine, so a TN436 colour can stretch past a month of typical use.

Buying the Full Colour Refresh

When levels fall together, lead with the set: the TN436 four-colour set costs $67.69, against $115.93 for black, cyan, magenta and yellow bought as singles — a $48.24 difference for identical cartridges. A TN433 set at $65.31 is listed too, though its cost per page runs higher.

The exception, plainly: colour use is uneven — a team printing mostly black text drains black long before yellow. When only one colour shows low, replace only that colour.

Fitting a Fresh Cartridge

1. Open the front cover and ease the combined drum and toner tray out toward you. 2. Free the cartridge for the depleted colour from its bay and set the old unit aside. 3. Hold the replacement level, rock it gently end to end, and pull away its protective cover. 4. Lower it into the bay with the same colour label, pressing until it locks. 5. Slide that bay's green tab side to side once, return the tray, close the cover and wait for the ready screen.

The Drum Unit, Explained Without a Sales Pitch

One DR431CL drum serves all four colours, rated around 30,000 pages at one page per job, extending toward 50,000 at three pages per job. The BU330CL belt and WT320CL waste box each rate near 50,000 pages. Clever Supplies carries no compatible DR431CL, only a genuine Brother listing, so no drum link appears here; source it as a genuine part when the machine asks.

Two Features That Separate the L8905

The 7-inch touchscreen. The largest display in this group holds up to 64 shortcuts, putting scan, copy and fax presets within one glance and one tap — practical when new staff learn shared equipment.

Cabinet-ready paper handling. Capacity starts at a 250-sheet tray plus a 50-sheet multipurpose tray and can reach 1,300 sheets, with an optional cabinet available. Add a 70-page feeder scanning two-sided pages at up to 58 images per minute, a legal-size flatbed, an integrated NFC card reader, and Wi-Fi, Gigabit Ethernet and USB. Duty cycle cap: 60,000 pages a month.
