If you have a printhead with one channel clogged, here is a little trick.
It will get you up and running until you find a replacement printhead.
Disclaimer: This only works when one channel clogged.
An XP-15000 has 6 color channels. That means two are being used by WHITE when printing DTF. If one channel is clogged, you can put ONE of the white cartridges in that color channel and move the clogged color to your other working channel.

For example, after buying this 20$ printhead, we discovered one channel was clogged. Since we needed to print ASAP, we decided to move one of our whites to the clogged channel. We then moved our black to the normal white channel.

Next Step is to set the ink order in your RIP software.
The below steps are for CADLINK v11.

The below settings are for the above cartridge configuration. White #2 is the clogged channel.
Make sure you do a couple head cleans to flush the channels!
