Drum unit OKI 42126608 Original for OKI C5100N/C5200/C5300/C5400 — black, 17,000 pages

Original OKI drum unit 42126608 is a replacement imaging component compatible with OKI C5100N, C5200, C5200N, C5300N, C5400 and C5400N colour printers. This black drum unit is designed to work with separate toner cartridges and image drums to maintain consistent monochrome imaging and stable print quality in office and workgroup environments. With an estimated page yield of approximately 17,000 A4 pages, the unit helps extend maintenance intervals and reduce overall running costs by allowing separate replacement of drum and toner consumables.

Advantages

The OKI 42126608 drum unit is an original manufacturer part that ensures compatibility and predictable performance with the listed OKI printers. Because the imaging drum is separate from toner cartridges, you can replace only the component that is worn, reducing consumables waste and lowering ongoing operating expenses. The unit’s black photoconductor surface is engineered for consistent density and reliable monochrome output across large print volumes, supporting stable single-pass, high-speed printing workflows.

Suitable for

• Office environments requiring reliable monochrome prints from colour OKI printers
• Workgroups with medium to high monthly print volumes
• Maintenance cycles where separate replacement of drum and toner is preferred
• Environments aiming to reduce total cost of ownership through targeted consumable replacement

How to use

Turn the printer off and allow it to cool according to the manufacturer instructions. Open the printer access panel and remove the used drum unit following the printer's user manual to avoid contact with the photoconductor surface. Unpack the OKI 42126608 drum unit and handle it by the designated rails or ends to prevent fingerprints. Slide the new drum into the correct slot until it clicks into place, then close the access panel and perform any recommended printer reset or drum counter adjustment as described in the printer documentation. Print a test page to verify installation and print quality.

Usage recommendations

Store spare drum units in a cool, dry place away from direct sunlight and heat sources. Do not touch the drum surface to avoid image defects. Replace the drum when print density decreases, or the printer indicates drum end of life. For best results, use original OKI consumables and follow the printer maintenance schedule.
