Refill Instructions for Brother LC-123, LC-125, LC-127 with syringe

These instructions show 2 options to refill Brother cartridges by dismantling the cover and adding filler openings to the ink chamber.

Remove the front cover above the ink outlet and air valve by using a small screwdriver. Carefully push in the 2 retaining collars and than push them rightwards as the first two pictures show. Afterwards you can carefully remove the cover from the ink chamber.

On the back cover the retaining collars are more difficult to reach. Please proceed particularly careful. Push the retaining collars in and than leftwards as the first two pictures show. Afterwards you can easily pull the ink chamber out of the cover.

There are several places which are suitable for a filler opening.

In the first approach you drill the filler opening into the upper left corner at the front of the ink chamber next to the air valve. As you can see in the left picture.

For the second option you drill the opening into the upper side of the ink chamber. The picture in the middle shows where. For better orientation we removed the side foils from the ink chamber. This step is not necessary for refilling.

The right picture shows the 2 options and the way to reseal these openings.

For option 1 it is sufficient to remove only the front cover above the ink outlet and air valve. Drill the hole into the upper left corner next to the air valve. Fill in the recommended amount of ink (depends on the cartridge type) through this hole. Reseal the opening with a sealing plug or hot glue. Press the front cover onto the ink chamber until the retaining collers click into place. The sealing plug is pressed firmly onto the ink chamber by the cover and therefore seals the opening securely.

For option 2 you need to remove both covers from the ink chamber. Fill in the recommended amount of ink into the ink chamber. Be careful not to damage the side foils with needle or syringe while refilling. Reseal the filler opening with a sealing plug or hot glue. Put the back cover onto the ink chamber and press until the retaining collers click into place. It is enough place available between ink chamber and cover for a plug that fits plain onto the chamber. The sloping back of the cover presses the plug firmly into place and seals the opening securely. At last attach the front cover onto the ink chamber and push until the retaining collars click into place.

For the optimal functionality of the refilled cartridge we recommend to reset the chip with the Chip Resetter for Brother LC-123, LC-125, LC-127 Cartridges. This way no warning messages occur when you start a printing job.
