How to choose the best ink for Brother MFC-J6945DW

When selecting ink for Brother MFC-J6945DW, we recommend matching the cartridge type to your real printing habits:

• Frequent printing (office, small business): choose LC-3239 XL cartridges, especially Black (BK), to reduce replacements and keep your workflow steady.
• Mixed printing (text + color charts): consider an LC-3237 CMYK multipack to stay fully stocked and avoid stopping mid-project.
• Occasional printing: standard cartridges can be sufficient, but it’s worth adding a cleaning fluid to your toolkit if the printer sits unused for longer periods.

Original OEM vs Compatible: Original OEM cartridges are made by Brother and are a safe, predictable choice. Our Compatible cartridges are an equally strong option—tested for everyday reliability and excellent print results, and they help significantly reduce cost per page. If you want the best balance of quality and savings, compatible ink for printer Brother MFC-J6945DW is often the smartest pick.

Common user issues with the Brother MFC-J6945DW – and how the right supplies help

Like many business inkjets, the MFC-J6945DW can occasionally show issues that are easy to solve with correct maintenance and supplies. Customers most often report:

• Faded prints or missing lines – typically caused by partially clogged nozzles; a head-cleaning cycle and cleaning fluid can help restore quality.
• Color imbalance – often happens when one color is close to empty; replacing the specific CMYK cartridge (C/M/Y/BK) fixes it quickly.
• High running costs – switching to LC-3239 XL or choosing our Compatible cartridges can noticeably reduce expenses.
• Ink drying when the printer is unused – printing a small color page regularly and keeping cleaning supplies on hand helps prevent recurring problems.
