A Scanner That Also Prints

It is tempting to file the MFC-L9570CDW as "the HL-L9310CDW with a scanner on top," but the scanner is the headline act. Its 80-page auto document feeder scans both sides of a sheet in a single pass at up to 104 images per minute, the document glass handles legal-size originals, and a 7-inch color touchscreen carries up to 64 custom shortcuts for scan-to-email, SharePoint, cloud services and SFTP. Print speed matches the print-only flagship at up to 33 pages per minute, with NFC badge authentication and the same 6,000-page monthly recommendation. One consequence matters for supply planning: pure scanning consumes no toner at all. It is the copying — every scanned page that comes back out as paper — that draws on the cartridges, so scan-first offices routinely see toner last far longer than the page counter on their print jobs alone would suggest.

Yields, Color by Color

Cartridge	Black	Cyan	Magenta	Yellow

TN436 (super high yield)	~6,500 pages	~6,500 pages	~6,500 pages	~6,500 pages
TN433 (high yield)	~4,500 pages	~4,000 pages	~4,000 pages	~4,000 pages

Brother's ratings follow ISO/IEC 19798 at 5% coverage, and at the top two tiers all four colors share one rating — convenient when a department copies color presentation packs as often as black text.

Cost per Page, From Our Own Shelf

Checked on our compatible product pages on November 2, 2026: the TN439 black costs about 0.33 cents per page ($29.49 over ~9,000 pages) and each TN439 color about 0.36 cents ($32.59). A TN436 black runs near 0.42 cents ($27.55 for ~6,500 pages) and its colors near 0.45 cents ($29.46). The TN433, flat-priced at $28.39, comes out around 0.63 cents for black and 0.71 cents for colors. In plain terms, a workgroup that copies 3,000 pages a month spends on the order of ten dollars a month on TN439 toner wear — and roughly twice that running TN433 — which is why the factory TN436 set is best treated as the starter, not the strategy.

Replacing a Cartridge

With the machine powered, open the front cover and slide the toner-and-drum tray out. The four units sit in a row, each holding one cartridge in its own drum. On the unit the display named, press the green lock lever and lift the empty cartridge out. Rock the replacement gently from side to side, remove its protective cover, and press it into the unit until the lever clicks. Slide that drum's green tab across and back to clean the corona wire, push the tray in, and close the cover. If a drum was ever replaced at the same visit, reset its counter from the touchscreen's supplies menu — toner swaps need no reset.

One Set or One Cartridge at a Time?

Our compatible TN439 four-color set was $79.02 at checking, against $127.26 for the four singles — a $48.24 saving. Sets make the most sense at natural change points: when the factory TN436 set is finishing and multiple colors are within a few hundred pages of each other, or when a department standardizes stock for several machines in this family. The disciplined exception is the lone empty color. If cyan alone is out and the other three show half their life, the $32.59 single is the right purchase and the set can wait for the next full change.

The Drum Underneath

The cartridges share one DR433CL drum unit, rated by Brother at approximately 50,000 pages with typical multi-page jobs (about 30,000 in single-page patterns). At this machine's recommended 6,000-page monthly ceiling that is the better part of a year of maximum-duty work; at ordinary office pace it can be several years. We do not currently carry a compatible DR433CL, so there is intentionally no drum link in this guide — when the time comes, the genuine unit is the one to buy, by that exact part number. Evenly repeating marks down every sheet, or a background haze that survives a cartridge change, point at the drum rather than the toner. The WT330CL waste toner box (about 50,000 pages) is the only other supply with a comparable lifespan.

Questions MFC-L9570CDW Owners Ask

Does scanning use up my toner? No. Scanning to email, folders or cloud services never touches the cartridges. Copying does, one page of toner for every page that comes out.

Can I fax without printing anything? Yes — incoming faxes can be forwarded to email or a network folder instead of paper, which keeps both toner and paper untouched until someone chooses to print.

My MFC came with TN436 cartridges. Is TN439 really the same fitting? It is. Same bay, same drum, no settings to change; the TN439 simply carries more toner, which is why it is the recommended replacement tier for this machine.

Does this model take the same toner as the HL-L9310CDW printer? Identical shelf — TN431 through TN439 and the DR433CL drum. One stock cupboard can serve a mixed fleet of both.

What does the 7-inch screen have to do with supplies? The touchscreen's supplies pages show per-color remaining life and let administrators build one-touch reordering shortcuts, so the low-color warning rarely becomes an empty-printer surprise.

Other Printers That Use TN439

The same cartridges also fit: HL-L9310CDW, HL-L9310CDWT, HL-L9310CDWTT and MFC-L9570CDWT.
