Thanks to this selection, you can quickly match the right toner for printer Oki MB491n to your expected monthly volume and keep a spare drum unit ready for uninterrupted printing. How to choose the right toner for Oki MB491n (and avoid common issues) When selecting a toner for Oki MB491n, start with two questions: how much you print and what kind of documents you produce. For occasional printing, a standard yield cartridge is usually enough. For frequent, daily printing, a higher-yield option helps reduce replacements and downtime. - Page yield: choose 7K or 12K options when you want fewer interruptions and a lower cost per page.
- Print symptoms: fading, streaks or repeated marks often indicate the drum unit is nearing the end of its life, not just an “empty” toner.
- Quality expectations: for invoices, contracts and small text, consistent black density matters—pair a good toner with a healthy drum.
- Error messages: if the printer reports toner/drum warnings, it may be time for a replacement or a careful reseat of the cartridge.
