Brother MFC-J6920DW Ink Cartridges
Your Brother MFC-J6920DW uses the LC131 / LC133 / LC135XL / LC137XL / LC139XL cartridge series. Since 07 Jan 2014, we have provided premium replacement options for this four-colour inkjet setup. In fast-paced business environments, managing separate ink depletion rates requires balancing text documents against graphics output. Rather than replacing entire multi-pack clusters prematurely, seasoned operators strategically track heavy black usage separately from colour consumption. Transitioning to high-capacity options provides extended duty intervals and minimises intervention overhead during heavy print runs.
Expected page output and replacement cycles
Page capacity varies heavily between text drafts and mixed office presentations. Genuine and compatible high-yield options offer predictable capacities under standardised industry criteria, where the black cartridge tracks independently from the cyan, magenta, and yellow tanks. Inkjet capacities are measured in compliance with the ISO/IEC 24711 standard.

Pro Tip
Always install high-yield LC139XL black and LC135XL colour cartridges rather than standard yield options for business work, because high-capacity cartridges contain significantly more ink relative to their plastic casing, reducing total environmental waste and drastically lowering print management overhead.
Frequently Asked Questions
Can I mix a genuine Brother black cartridge with compatible LC135XL colour cartridges?
Yes, the printer infrastructure permits running a combination of genuine and compatible cartridges simultaneously. The microchips communicate independently with the logic board, allowing you to transition between different ink brands piece-by-piece as individual colours run low.
Why does the printer refuse to print black text when a colour cartridge is empty?
Brother inkjet systems enforce a print blocking safety threshold when any individual ink tank is completely depleted. This design choice prevents air from entering the delicate thermal printhead nozzles, which would otherwise cause irreversible heat damage and banding issues across the nozzle plate.
What is the physical size difference between standard LC133 and high-yield LC139XL cartridges?
The exterior plastic cartridge dimensions are identical across the entire series, meaning high-yield variants fit perfectly into the exact same slots without modifications. The difference lies entirely within the internal ink reservoir, which holds a substantially higher volume of liquid ink.
