Frequently Asked Questions

Why does the cyan cost over a hundred dollars more than the black when both are rated at 9,000 pages?

Because color toner is the expensive half of color printing, and the TN439C's price tag shows it plainly: $241.72 against the black cartridge's $140.65 — a gap of $101.07 for the same 9,000-page rating, which puts cyan at roughly 2.7 cents a page next to black's 1.6. Color pigments cost more to make, color cartridges sell in smaller numbers, and on a flagship machine there is no cheaper genuine route around it. What you can control is the buying: at $96.69 under its $338.41 list price, this is the genuine cartridge bought at a sensible discount rather than at full retail.

How does cyan actually get used up on a machine like this?

Faster than most people expect, because modern office color is cyan-heavy. Charts and graphs lean on blues and greens, corporate templates carry colored headers and logos on every page, and even documents that look mostly black are often printed in a composite mode that lays color underneath. On top of that, these printers run periodic calibration cycles that draw a little of every color. A 9,000-page rating assumes standard test coverage; a graphics-heavy department will see fewer real pages, which is true of every color cartridge from every maker.

How can I tell it is the cyan running low, and not one of the other colors?

Read the prints before you read the display. When cyan fades, skies and water wash out, blues drift towards purple as magenta takes over the mix, and greens lose their depth and turn muddy. The machine's supply screen also reports each cartridge separately, so a low TN439C reading alongside those symptoms settles it. Replacing only the cyan is the correct move — the other cartridges keep whatever toner they still hold.

Which printers does the TN439C fit?

Four models carry this cyan in our compatibility data: the HL-L9310CDW, HL-L9310CDWT and HL-L9310CDWTT printers, and the MFC-L9570CDW all-in-one. These are Brother's flagship color machines, and the TN439C is the ultra high-yield cyan made for them — the largest cyan cartridge the platform accepts, matched in capacity to the other three TN439 colors.

Should a color cartridge this size be bought one at a time or as a set?

One at a time, as each color calls for it, suits most offices: the four colors deplete at different rates, and there is no requirement to change them together. The exception is a planned full refresh — a new machine being commissioned, or all four colors genuinely near empty together — where changing the row in one session saves repeated interventions. Either way, a spare TN439C keeps for a long time sealed in its box, so buying ahead of the warning is safe.

What are my options if it arrives damaged, or I order the wrong color?

Genuine Brother products bought here can be sent back within 30 days in all cases, under the terms set out on our shipping and returns page, and the cartridge itself is covered by Brother's manufacturer warranty rather than a store scheme. Keep the box until you have fitted the cartridge and printed a test page. Our support hours are Monday to Friday, 9 AM to 5 PM CST, if anything needs sorting out.
