Frequently Asked Questions

Why would a copy and scan desk replace all four cartridges at once?

On a DCP-L8400 that spends its day copying and scanning, the four colors rarely wear evenly — black takes the document load while the colors fade in the background. Swapping the full set resets the whole desk to a known starting point: no second interruption a week later when a color gives out mid-job. This set covers roughly 2,500 black pages and 1,500 pages per color before you think about toner again.

What does the set actually save over buying the cartridges one by one?

The four singles bought separately total $129.91 — the black at $31.33 and each color at $32.86. The set is $74.41, so you keep $55.50. For a desk that goes through full sets regularly, that gap adds up fast across a year of copying.

Which printers does this TN331 set fit?

This TN331 four-color set works in these Brother machines: HL-L8250CDN, HL-L8350CDW, HL-L8350CDWT and MFC-L8600CDW If your DCP-L8400 is the desk's workhorse, this is the set built for it — one box, all four positions refreshed.

Is there a longer-lasting option for the same printer?

Yes. The TN336 high-yield cartridges fit the same machines and stretch the black to about 4,000 pages and each color to about 3,500. If your copy volume keeps climbing, TN336 is the step up; the TN331 set here is the standard-yield refresh at the lower upfront price.

Do I have to install all four cartridges the day the box arrives?

No. Each cartridge is sealed and changes independently, so you can install the black now and hold the colors until the printer asks for them. Many desks do exactly that — replace what is empty, shelve the rest as the desk's built-in spares.

What protection backs the set if a cartridge misbehaves?

Every Clever Supplies cartridge carries a 1-year warranty plus 1-year free returns under our shipping and returns policy. Orders ship from our warehouses in IL, PA, GA and CA, and support is available 9 AM–5 PM CST if a cartridge ever gives you trouble.
