Drum Unit OKI 01333301 Original for OKI 7470dfn / 7470dn / 7480dfn, 1 pc

Original OKI drum unit 01333301 is designed for use with OKI laser printers 7470dfn, 7470dn and 7480dfn. Supplied as a single replacement drum, this genuine imaging unit restores the printer's ability to transfer toner accurately to paper, helping to maintain consistent print density and image stability in office or light-production environments.

Advantages

This original OKI drum unit is manufactured to match the printer's imaging system specifications, ensuring proper mechanical fit and electrical contacts. Using an original drum helps preserve expected print quality, reduces the risk of streaks or uneven density, and supports the printer's reliability and service intervals. The unit is easy to install and intended for straightforward swap-out during routine maintenance.

Suitable for

• Replacing worn imaging drum in OKI 7470dfn, 7470dn and 7480dfn printers
• Routine maintenance in small office and departmental print environments
• Situations requiring consistent monochrome print density and image stability
• Servicing printers to prevent print defects such as ghosting or banding

When it may not be suitable

This drum unit is intended specifically for the listed OKI models and will not fit printers from other series or brands. It is not a toner cartridge; the drum works together with the correct toner supply, so replacing the drum alone will not address issues caused by incorrect or depleted toner.

• Type: Imaging drum unit (single unit)
• Color support: Monochrome (black toner transfer)

How to use

Turn the printer off and follow the manufacturer's service instructions for safe access to the drum compartment. Remove the used drum unit according to the printer guide, handle the new drum by its designated grips to avoid contact with the drum surface, and insert the replacement until it locks into place. After installation, run a test print or calibration routine as recommended by the printer to verify correct alignment and image quality. Dispose of the removed drum according to local electronic waste regulations.

What to consider before purchase

• Ensure your printer model is one of the compatible models listed above
• Confirm whether your printer also requires a toner cartridge replacement at the same time
• Check warranty and recycling options for original manufacturer parts
• Verify the expected service life or page yield in your maintenance plan

Recommendations

Use genuine OKI replacement parts and follow scheduled maintenance intervals to maintain consistent monochrome print quality and minimize downtime. Store the drum unit in its original packaging away from direct light and extreme temperatures until installation.
