How to choose the right toner for KM BizHub C450 When selecting a toner for KM C450, start with two simple checks: the device name and the cartridge code. For this model, the key toner series is TN-310 (K/C/M/Y). For imaging components, look for the IU series (drum units). If your office prints a lot of colour, consider keeping at least one spare of each colour—downtime in an A3 MFP environment is expensive. Original OEM vs Compatible—what’s the practical difference? - Original OEM – manufacturer-standard consumables, often chosen for unified corporate procurement.
- Compatible – a smart way to reduce printing costs while maintaining excellent print quality; our compatible cartridges from DrTusz.pl are as good as the originals in everyday use, offering reliable operation and strong, consistent colour.
Common user issues and what they usually mean Users of KM BizHub C450 sometimes report typical print-related issues. In many cases, the solution is simply choosing the correct consumable or replacing the right component in time: - Faded prints or uneven coverage – often indicates low toner level, incorrect cartridge, or a drum unit approaching end of life.
- Streaks, spots or repetitive marks – commonly linked to the drum unit (IU) rather than the toner itself.
- Colours not matching expectations – can happen when one colour runs low; replacing the correct TN-310 colour usually restores balance.
- Printer message about consumables – double-check the code (TN-310 or IU series) and the colour; our product names make identification easy.
