Frequently Asked Questions

Why does this black cartridge sit in the sweet spot of its family?

It is rated at 6,500 pages for $31.68 — about 0.49¢ per page. The TN433BK below it gives 4,500 pages, and the TN439BK above it gives 9,000 at a higher price per box. For a steady office workload, this tier usually delivers the most black printing per dollar without paying for capacity you may not use for a year.

How does its cost per page compare with the TN433BK?

The TN433BK yields 4,500 pages; this cartridge yields 6,500 for only a modest step up in price, which is why the per-page cost drops to roughly 0.49¢. You also swap cartridges less often — about one change here for every one and a half changes on the smaller tier, in the same machines.

Which printers does the TN436BK run in?

It fits the HL-L8360CDW, HL-L8360CDWT, HL-L9310CDW, MFC-L8900CDW and MFC-L9570CDW. Every machine on that list also accepts the TN433 and TN439 tiers, so picking this middle tier needs no other change to your setup.

How long should 6,500 pages last in practice?

At around 400 black pages a month, expect roughly sixteen months; at 1,000 pages a month, about six and a half months. The rating uses the standard 5% page coverage, so dense documents with heavy fills will land below it and plain text will track it closely.

When would the TN439BK make more sense than this one?

If your black volume is very high and every cartridge change interrupts a busy workgroup, stepping up to the TN439BK stretches each interval to 9,000 pages. For light or moderate use, though, the extra upfront cost sits in a cartridge that takes much longer to finish.
