Choose the Right Toner Capacity
Compatible B3442 / MB3442 printers offer three genuine Lexmark Return Programme toner capacities, allowing you to choose the cartridge that best matches your monthly print volume.
| Cartridge | Capacity | Approx. Yield | Best For |
| B346000 | Standard Yield | 1,500 pages | Light / occasional printing |
| B346H00 | High Yield | 3,000 pages | Regular office printing |
| B346X00 | Extra High Yield | 6,000 pages | Higher-volume business printing |
Why Choose the B346H00 High Yield Cartridge?
The B346H00 sits in the middle of the three available toner capacities and is a practical choice for businesses with moderate printing requirements.
Compared with the 1,500-page standard-yield B346000, the B346H00 provides approximately double the rated page capacity. This means fewer cartridge changes and potentially a better cost per page while avoiding the higher upfront purchase price of the 6,000-page cartridge.
If your printer is used heavily every day, however, we recommend considering the Genuine Lexmark B346X00 Extra High Yield Black Toner Cartridge, which doubles the rated capacity again to approximately 6,000 pages.

It is well suited to professional monochrome documents including:
- Invoices and quotations

- Medical and professional records

- General office printing
Lexmark Return Programme Cartridge
