Frequently Asked Questions

What does the per-cartridge price drop to in this three-pack?

Bought one at a time, the TN439BK is $33.91. In this three-pack at $64.76, each cartridge costs $21.59 — you save $36.97 against three singles. Spread over the pack's 27,000 rated pages, black printing falls to about 0.24 cents per page.

How long might 27,000 pages last a busy office?

At 1,500 pages a month, roughly a year and a half. At 3,000 pages a month — a genuinely busy departmental printer — about nine months. Either way, three cartridges is a comfortable planning horizon: long enough to forget about toner, short enough that nothing sits on a shelf for years.

Do these cartridges work in my printer?

Yes, if you run one of the compatible models: this pack contains standard TN439BK cartridges for HL-L9310CDW, HL-L9310CDWT, HL-L9310CDWTT and MFC-L9570CDW. Each installs exactly like a single cartridge, one at a time, as the previous one empties.

Can the three cartridges be split across two different printers?

They can. Nothing ties the pack to a single machine — put one in the front office printer and keep the other two as shared spares, or feed all three to one high-volume unit. Each cartridge is sealed and tracked independently once installed.

How does the drum unit factor into a pack this size?

These printers use a separate DR890 drum unit rated around 30,000 pages, so this pack's 27,000 pages of toner roughly match one drum's working life. When the printer eventually asks for a drum, that is a separate purchase — toner and drum wear on their own schedules. Planning both together keeps maintenance surprises to a minimum.

What if I need to send something back?

Returns stay simple: every cartridge carries a twelve-month warranty, and return shipping is on us for the first year. The step-by-step process is spelled out on the shipping and returns page. If you would rather talk first, support is available Monday through Friday, 9 AM to 5 PM CST.

About This TN439BK Black 3-Pack
