Dell 330-3110
The 330-3110, X730H, U789H, and related black cartridges fuel Dell’s 7330 and 7330dn high-speed monochrome printers. Single-cartridge mono printing keeps things simple — one black cartridge, available in yields for different volumes.
For machines that print thousands of pages monthly, the higher-capacity options in this family minimize downtime and cost per page. We stock genuine OEM Dell 7330 toner cartridges plus compatible versions with equivalent yields and sharp, consistent black output.

Frequently Asked Questions
Are X730H and U789H the same cartridge as 330-3110?
Yes: X730H and U789H are alternate Dell part numbers for the 330-3110 toner cartridge, and 593-10358 is the kit number for the same supply. Whichever number is printed on your current cartridge, any of these four identifies the correct replacement.
What is the best way to extend the life of the 330-3110 cartridge?
Print in draft or toner-save mode for internal documents: it cuts toner use dramatically with text that is still perfectly readable. Reserve full-quality mode for customer-facing output, and avoid printing solid black backgrounds or banners that drain the cartridge fast.
Can I refill this cartridge myself instead of replacing it?
Refill kits exist, but refilled cartridges often print inconsistently and can leak toner inside the printer, and a leak cleanup costs more than the savings. For reliable output, especially on a work printer, a new 330-3110-series cartridge (genuine or quality compatible) is the safer economics.
