Making some progress. I did an initial fill and now all but one channel is working fine. Not sure why it is giving me fits. I guess I will let it sit overnight, then maybe pt the flushing cartridge back I that one channel and see if I can flush it out.
Is the one channel that isn’t working fine printing any nozzles, or is the entire channel blank?
What channel isn’t working?
Is the air vent hole open on that refill cart?
“Purge lines” empties the ink lines, so it makes sense that nothing was printing after doing that, because an ink charge is necessary to get ink from cartridges to the print head again (to fill the internal ink system). Now that you have done the initial fill cycle, you have purged most of the air and most channels are printing well again. Letting it sit for a few hours or overnight is a good idea, but you may also need to do a second initial charge cycle to purge any remaining air, as well as PiezoFlush to get InkThrift flowing full-strength.
