InkNI Toner Cartridge TN660

Size & fit

When a Brother laser printer is running low on black toner, replacing the cartridge with the right model matters more than choosing by brand name alone. This InkNI four-pack is made as a compatible TN660 cartridge and is also described as compatible with TN630 printers. Its listed yield is up to 2,600 pages per cartridge, though actual results can vary with what you print.

The listed printer models include Brother HL-L2300D, DCP-L2520DW, DCP-L2540DW, HL-L2305W, HL-L2315DW, HL-L2320D, HL-L2340DW, HL-L2360DW, HL-L2380DW, MFC-L2680W, MFC-L2685DW, MFC-L2700DW, MFC-L2705DW, MFC-L2707DW, MFC-L2720DW, and MFC-L2740DW. Match your printer’s exact model number against that list before buying, compatibility with one model in a series does not establish compatibility with every Brother printer.

For a small office, the pack could mean keeping a spare ready instead of placing a new order each time toner runs out. Would that convenience matter more than sticking with the printer maker’s own cartridge? That is the central tradeoff here: this is a compatible replacement, not an original Brother cartridge.

Pros

• Four black cartridges are included, with a listed yield of up to 2,600 pages each and 10,400 pages total.
• The product description names a fairly broad group of compatible Brother models, including several HL, DCP, and MFC printers.
• InkNI states that the cartridges come with a two-year manufacturer warranty and 24/7 customer support.

Worth considering if you use one of the listed printers and want multiple replacement cartridges on hand. The listing also says the TN660 offers 1,400 more pages than a compatible TN630 cartridge while providing the same quality, treat that as the seller’s comparison, not an independent performance guarantee. A practical limitation from the way it is set up is that its value depends on matching the exact printer model and getting through the included toner. If your printing needs are light, keeping several cartridges in reserve may be less useful than buying one replacement at a time.

Spec sheet

• Type: Compatible black laser toner cartridge
• Model: TN660, also described as compatible with TN630
• Pack size: Four cartridges
• Listed yield: Up to 2,600 pages per cartridge, 10,400 pages total
• Printer compatibility: Select Brother HL, DCP, and MFC models listed above
• Warranty: Two years, according to the product description

InkNI also says the cartridges are produced under ISO 9001, ISO 14001, and STMC standards, and describes the output as having uniform black density, firm fixation, and clear printouts. Those are manufacturer-provided details, the listing does not give test conditions for the stated page yield. If predictable results for a particular document type are essential, that missing context is worth bearing in mind.

Should you buy it?

This four-pack makes the most sense for someone with a printer explicitly named in the compatibility list who prints often enough to use several cartridges. It offers a bulk-replacement approach, choosing an original cartridge instead may suit buyers who would rather stay with the printer manufacturer’s own supplies. It’s not for you if your printer model is absent from the list, or if you specifically need an original Brother cartridge. Check the model number on the printer before choosing, and weigh the stated yield against how quickly you actually use toner.
