• Original OEM Transfer Unit Brother BU‑223CL (BU‑223CL) and Original OEM Transfer Unit Brother BU‑229C (BU229CL) – important for consistent colour transfer and preventing repeating marks.

Keeping these parts in mind prevents downtime and helps your toner for Brother MFC‑L3740CDN perform at its best.

Common user issues with MFC‑L3740CDN – quick, practical tips

• Streaks or repeating marks: often linked to the drum unit or transfer components rather than the toner. Consider checking DR‑248CL.
• Background shading / grey haze: can appear when the waste toner system is near full or when internal components need replacement—check WT‑229CL.
• One colour looks weak: replace the specific colour toner (C/M/Y) or switch to XL if you print colour frequently.
• “Replace toner” too soon: ensure you’re using the correct TN‑248 series for this model, and consider multipacks to keep colours balanced.
