Compatible Black Cartridge for Dell 5230/5350

This Laser Tek Services toner cartridge replaces Dell OEM 3306991 and fits the Dell 5230N and 5350DN printer series. It is a new aftermarket single pack designed for offices that need reliable monochrome output without paying original-equipment prices. The cartridge installs directly into the listed Dell models and is ready to print immediately.

ISO-Certified Build and Consistent Yield

Manufacturing follows ISO 9001 and ISO 14001 factory standards and conforms to US patent regulations. Each unit is rated for up to 21,000 pages at five percent coverage, delivering crisp black text from the first page to the last. The consistent yield helps keep total cost of ownership low across high-volume print runs.

Upgrade from Worn or Expensive OEM Cartridges

The cartridge replaces an exhausted or costly original Dell 3306991 unit, restoring full print quality at a lower per-page cost. It is not suited for colour printing, for printers outside the 5230N and 5350DN series, or for users who require multi-pack bundles in a single purchase.

Questions about this item

How do I install the Laser Tek Services 5230 cartridge in my Dell 5230N or 5350DN printer, and what step is commonly missed?

Open the front cover, remove the old cartridge, shake the new 3306991 gently side to side to distribute toner, pull the sealing tape straight out, then insert until it clicks. Many users forget to remove the tape completely.

What maintenance or replacement will the 3306991 cartridge need after printing its rated 21000 pages?

Once the 21000-page yield at 5% coverage is reached, the cartridge is empty and must be replaced with a new unit; no separate drum or developer maintenance is required for this all-in-one design.

What limit appears first during long, continuous print runs with this 5230-compatible toner?

The page-yield ceiling of 21000 pages at 5% coverage is the first hard limit; sustained heavy coverage will reach it sooner, requiring a fresh cartridge.
