Rumpuyksikkö TB TB-DR248N CMYK Brother-tulostimille, 100% uusi varaosa

Replacement drum unit TB-DR248N CMYK for Brother printers by TB is supplied as a set of four units designed to transfer toner evenly onto paper in compatible laser printers. The product is described as 100% new and intended to restore or maintain consistent print density and colour reproduction for office documents, marketing materials and everyday printing tasks. It fits Brother models that use the DR248N series and is intended as a like-for-like replacement of worn or depleted drum units.

Advantages

The TB drum unit set provides uniform toner transfer across CMYK channels, which helps produce consistent grayscale and colour output page after page. Being supplied as a full CMYK set simplifies maintenance cycles and reduces downtime compared with replacing individual colours. The units are new production parts manufactured to match the mechanical and electrical interfaces typical for Brother DR248N-compatible printers, enabling straightforward installation and expected functional compatibility.

Suitable for

When it may not be suitable

This TB drum unit set is only suitable for printer models that accept DR248N-style drum units. It will not function in Brother models that use a different drum design, cartridge format, or integrated drum-and-toner units. Users with printers that are beyond manufacturer support or with incompatible firmware versions may experience incompatibilities.

Key specifications

How to use

Switch the printer off and allow it to cool if recently used. Open the printer access panel according to the printer manufacturer instructions, remove the used drum units following safety guidance, and install the TB-DR248N CMYK units into their corresponding colour positions. Close the access panel and perform any printer-specific drum reset or calibration routine recommended by the printer’s service manual to ensure correct colour alignment and page counts. Dispose of old drum units responsibly according to local electronic waste regulations.

What to consider before purchase

Recommendations

For consistent print quality, replace all four drum units as a set when colour shifts or print defects appear, and run the printer’s calibration routine after installation. Store unused drum units in a dry, dust-free environment away from direct sunlight to prevent premature degradation of the photoconductor surface.
