Dell 330-5207
The 330-5207 and U903R black cartridges power Dell's 3330 and 3330dn monochrome lasers. Both are single black cartridges for a mono machine — no color set to manage — so restocking is as simple as keeping one spare on the shelf.
This cartridge set covers the yield options for the 3330 family, which means you can match cartridge size to how much your office actually prints. We carry genuine OEM Dell 330-5207/U903R toner alongside compatible versions that print the same sharp, smudge-free pages for less.

Frequently Asked Questions
Is U903R the same cartridge as 330-5207?
Yes: U903R is Dell's alternate part number for the 330-5207 black toner cartridge; they are the identical supply in different packaging codes. Order either number and it fits the same slot.
How often should a small office expect to replace the 330-5207?
A small office printing 500-800 pages a month will typically get several months from one 330-5207 cartridge at standard coverage. Watch the printer's toner gauge rather than the calendar: reorder when it drops below 15-20 percent so you are never caught mid-project.
The printer makes a grinding noise when the cartridge is installed, should I worry?
A brief mechanical sound during warm-up is normal, but persistent grinding points to a cartridge that is not seated correctly or has a damaged gear, so remove the 330-5207 or U903R cartridge and reinstall it firmly until it clicks. If the noise continues with the cartridge properly seated, try a different cartridge to isolate whether the printer's drive mechanism is the problem.
