E-Z Ink TN660 Black Toner Cartridge

When a home office or small workspace needs black-and-white documents in batches, replacing toner in the middle of a print run is a hassle. This E-Z Ink TN660 cartridge set includes four black laser toner cartridges, with compatibility listed for a range of Brother printers. It’s aimed at buyers who want replacement toner on hand and print mostly text or other monochrome documents. The advertised page yield is tied to a specific coverage estimate, so treat it as a reference rather than a promise for every job.

Key specifications

This is a four-pack of black TN660 toner cartridges, also identified as TN-660 and compatible with TN630/TN-630 cartridge numbers in the product description. E-Z Ink lists an estimated yield of about 2,600 pages per cartridge, or up to 10,400 pages for the set, based on 5% coverage of A4 paper. That qualification matters: a page with dense text, graphics, or large dark areas uses toner differently from a lightly printed page. The stated yield is useful for comparing pack sizes, but your actual results will depend on what you print.

The cartridges are described for black-and-white laser printing. The listed compatible printers include Brother HL-L2300D, HL-L2340DW, HL-L2380DW, MFC-L2680W, and MFC-L2740DW, among other HL, MFC, and DCP models. Check your exact printer model and the cartridge number it uses before ordering, a shared brand name alone does not establish compatibility. On the spec sheet, the four-cartridge quantity and listed printer range are the main buying details, while details such as cartridge dimensions and installation steps are not provided.

Who it’s for

It makes sense if you already use a compatible Brother laser printer and go through black toner steadily. For example, keeping a spare cartridge nearby can help when you’re printing a stack of forms or work documents and the current cartridge runs out. Buying four at once also suits someone who would rather stock replacements than reorder after each cartridge is used.

Not the best choice if your printer is not among the compatible models, or if you need color printing: this set is black toner for laser printers. It may also be more toner than you need if you print only occasionally. In that case, a smaller replacement purchase could be a better fit than storing several cartridges. The description does not give storage guidance or installation details, so don’t assume specifics that aren’t listed.

Everyday use

The practical benefit here is having multiple replacements ready for routine monochrome printing. That can be useful for invoices, forms, and other text-heavy pages, where a black laser cartridge is the relevant supply. This is a bulk-buy approach rather than a single-cartridge replacement: it favors fewer repeat purchases, while asking you to confirm compatibility and have room to keep the extra cartridges. E-Z Ink describes the output as crisp black-and-white laser prints, but the supplied information does not include independent print testing or a guarantee of a particular result in every printer.

Before you decide

Which printers are listed as compatible? The description names several Brother HL, MFC, and DCP models, including the HL-L2300D, HL-L2340DW, MFC-L2680W, and DCP-L2540DW. Match your exact model to the full compatibility list before choosing.

How many cartridges are included? The product is described as a four-pack of black TN660 cartridges.

Is the advertised yield guaranteed for every page? No. The estimate is based on 5% coverage of A4 paper, so pages with heavier toner coverage may produce a different count.

Should you buy it?

Choose this E-Z Ink set if your Brother printer is listed, you need black laser toner, and having four replacements available suits your printing routine. The page-yield estimate can help with planning, but it depends on the stated coverage condition and should not be treated as an exact count for your documents. If you print infrequently, need color, or can’t confirm your printer’s cartridge compatibility, a different quantity or cartridge type is the more sensible direction.
