Product Description
The Brother TN540 compatible black toner cartridge from Castle Ink is a direct drop-in replacement for the OEM Brother TN540, built for Brother HL-5000 series monochrome laser printers. It’s an economical way to keep your Brother printer in service without paying OEM prices, while still meeting the print-quality expectations of a business or photo-grade workflow.
Black is the workhorse of the set — the cartridge most owners replace first and most often. Castle Ink’s TN540 is filled with pigment-grade carbon black for dark, dense text and clean bar codes that scan reliably the first time. Every cartridge is assembled with a fresh chip (where applicable), color-balanced toner, and OEM-grade mechanical components, then leak/seal tested before it ships. Castle Ink backs the TN540 with a 100% satisfaction guarantee — if you’re not happy with print quality or yield, we replace or refund.

Frequently Asked Questions
Will using the TN540 void my Brother printer warranty? No. Under the U.S. Magnuson-Moss Warranty Act, your printer manufacturer cannot void your warranty solely because you installed a compatible (non-OEM) cartridge.
How does print quality compare to the genuine Brother cartridge? The TN540 is built to match OEM toner densities, so day-to-day output should look essentially identical. If you ever see a difference, our satisfaction guarantee covers a free replacement or refund.
How fast will my order ship? Orders placed before 2pm ET ship the same business day from our U.S. warehouse with free standard shipping. Faster options are available at checkout.
