Introduction: Brother GT3 - White Tube Cleaning

White Tube Cleaning step by step.

To clean all 4 white channels it will take approx. 45min.

Step 1: Retract Pallet

This will make it easier to get around.

Step 2: Enter Maintence Menu

Press the Menu Button.

Navigate with the arrow keys to select the Maintenance Menu and press "OK".

Step 3: Select White Tube Cleaning

Press "OK" to select White Tube Cleaning.

Within the White Tube Cleaning Menu choose "All Whites". This will ensure that the ink currently in the system will be first returned into the cartridges before starting the cleaning sequence.

If you instead choose a single channel the cleaning process will start immediately for the selected channel.

Step 4: Check Waste Ink Level

Confirm that the waste ink container is less than 3/4 full and that the waste line is properly seating into the container.

If you forget you will have a mess!

Step 5: Retrieve White Ink

Wait for the ink to be recollected in the cartridges.

Step 6: Insert Maintenance Cartridge

Retrieve the Maintenance Cartridge from the lower holding bay.

Disconnect the tube and plastic stopper from it's holder and thread the tube without the stopper through the cap onto of the Maintenance bottle.

Once the tube is threaded through the cap push back into the stopper. This will ensure that the tube does not fall out of the bottle while moving back and forth.

Insert the prepared Maintenance Cartridge into the specified channel on the display panel. You can rest the Maintenance Bottle on the CMYK cartridges to prevent having to move it back and forth.

Once the above is completed press "OK".

Step 7: Close Air-in Cap

Make sure the small cap attached to the Maintenance Cartridge is attached to the filter port.

Once Confirmed press "OK".

Step 8: Open Air-in Cap

Make sure the small cap attached to the Maintenance Cartridge is detached from the filter port.

Once Confirmed press "OK".

This will allow bubbles into the ink lines to assist in cleaning out any settled white ink pigments.

This part of the process will take approx. 10 min.

Step 9: Insert Filter Cartridge

Insert the Filter Cartridge into the specified channel on the display panel.

Once Confirmed press "OK".

Step 10: Insert Maintenance Cartridge

Retrieve the Maintenance Cartridge from on top of the cartridge bay.

Insert the prepared Maintenance Cartridge into the specified channel on the display panel. You can rest the Maintenance Bottle on the CMYK cartridges to prevent having to move it back and forth.

Once the above is completed press "OK".

Step 11: Close Air-in Cap

Make sure the small cap attached to the Maintenance Cartridge is attached to the filter port.


Once Confirmed press "OK".

Step 12: Repeat Steps for Next Channel

Repeat Steps 6 - 11 for the channel on the display. You will have to repeat this for all white channels for a total of 4 cycles.

Remove the Maintenance Cartridge from the completed channel and insert the Filter Cartridge.

Step 13: Organize Ink Cartridges

Once completed you should have your White Ink Cartridges in order on top of the cartridge bay.

Filter Cartridges should be installed in all 4 White Channels.

Leave the Printer powered "ON" until ready to resume production, at which point you will complete the "Load White" procedure.
