• Original OEM – manufacturer-spec consumables, ideal for strict corporate procedures.

Replacing the correct drum unit or the waste toner tank for KM BizHub C4000i at the right time can restore print clarity immediately and help prevent downtime—especially important in offices where the printer is a shared resource.

How to choose the right toner for KM BizHub C4000i (and avoid common issues)

When choosing toner for KM BizHub C4000i, start with your printing habits and what you want to optimise—cost, standardisation or maximum convenience. We encourage you to use these practical tips:

• Match the code: for toners, look for TNP-81 and the corresponding part numbers (e.g., AAJW151 for Black).
• Choose OEM vs compatible consciously: OEM is a classic choice; our compatible cartridges provide excellent quality and are a smart way to lower operating costs.
• Don’t ignore maintenance parts: recurring streaks, background haze or colour instability often point to a drum unit nearing end-of-life, not a faulty toner.
• Printer messages matter: if the device indicates a full waste toner container, replacing the KM WB-P08 restores normal operation quickly.
• Keep a spare black toner: in office workflows, Black is usually the fastest to run out (documents, invoices, text-heavy prints).
