Brother DCP-T710W Black Not Printing

Date: [18th Dec 2025]

I’d like to share my experience solving a common issue with ink-tank printers: black ink stops printing after a refill. This typically happens when you refill the tank after the ink level has already dropped too low, allowing air to enter the hose that feeds ink to the print head.

The printer may not show any error messages—it simply continues printing without black ink. This can actually damage the print head over time, especially in thermal-type print heads, which rely on a constant ink supply for cooling.

My Specific Case

This happened on my Brother DCP-T710W wireless office printer. I refilled the black ink after noticing it had fallen below the minimum level. It printed a few pages normally before the black ink began to blur and then disappeared entirely.

Fortunately, I found a helpful video by an Indian creator that explains how to force the printer to re-pump ink from the tank into the print head. You can watch it below:

Step-by-Step Solution

Here’s a summary of the steps shown in the video:

1. Enter advanced maintenance mode:
   Press Menu → Mono → Menu.

2. Select the first code:
   Use the Up button to choose 7, then press OK.

3. Select the second code:
   Use the Up button to choose 6, then press OK.
   (The display should now show 76.)

4. Enter the sub-code:

   • Use Up or Down to select 3, then press OK.
   • Repeat to select 0, then press OK.

5. Start the cleaning cycle:
   Press the Mono button to begin cleaning and re-pumping.
   Important: Ensure there is no paper in the bypass feeder at the back.

6. Repeat if necessary:
   Wait for the cycle to complete. If the ink still doesn’t flow, repeat the process.

Why This Works

This procedure activates a deep cleaning cycle that forces ink through the system, purging air bubbles from the hose and restoring proper flow to the print head.

Final Tips

• Refill ink before it falls below the minimum level to prevent air from entering the hose.
• Perform regular nozzle checks to catch flow issues early.
• Keep spare ink on hand to maintain consistent levels.
