Product Description
The Dell 331-0778 compatible black toner cartridge from Castle Ink is a direct replacement for the OEM Dell 331-0778, built for Dell color and mono laser printers. It’s an economical way to keep your printer in service without paying full OEM prices, while still meeting the print-quality standards your team expects.
The 331-0778 delivers dense, dark black for sharp text, line work and reliable bar-code scanning. Castle Ink uses finely ground monochrome toner with consistent particle size so output looks crisp at first print and stays consistent through the life of the cartridge. Every 331-0778 is assembled with a fresh imaging chip (where applicable), color-balanced toner powder, then individually tested before shipping. Castle Ink backs every 331-0778 with a 100% satisfaction guarantee: if you aren’t happy with quality or yield, we replace or refund it.

Frequently Asked Questions
Will the 331-0778 void my Dell 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 Dell 331-0778? The 331-0778 is engineered to match the OEM cartridge’s particle size, charge profile and 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. Expedited options are available at checkout.
