How to choose the right toner for printer KM BizHub C300i

Dear Customer, when selecting a KM BizHub C300i toner, we recommend checking two things first: the exact cartridge code and the color. For this model, the commonly used series is TN-328 (K/C/M/Y). If your priority is predictable, manufacturer-standard operation, choose Original OEM. If you want to reduce printing costs without sacrificing results, choose our compatible options—our compatible toner for KM BizHub C300i is designed to deliver the same everyday quality and reliability as the original.

Also consider your printing habits:

• If you print mainly documents: focus on TN-328K (Black) availability and keep a spare.
• If you print color charts, offers, graphics: keep a balanced CMY set to avoid interruptions.
• If you notice quality changes over time: consider whether a drum unit or transfer unit may be due for replacement, not just the toner.

Common issues with C300i printing – and what usually solves them

Many users replace toner first—and that’s often correct. But in office devices like the KM BizHub C300i, print quality and error messages can also be linked to maintenance parts. Here are typical situations and the most common solutions:

• Streaks, repeating marks, uneven coverage – often connected to a worn drum unit (DR-316K or DR-316 CMY) rather than the toner itself.
• Colors look dull or inconsistent – check if a specific color toner is low, and consider the condition of the transfer unit for stable color transfer.
• Message about waste toner – replace the waste toner tank WX-107 to keep the device clean and prevent toner overflow issues.
• Frequent maintenance prompts in high-volume printing – for heavy workflows, components like the developer can be essential for long-term stability.
