One position, VM, was giving problems (banding due to dirty nozzle, and cartridge showing up as X when cleaning). I had to reinsert the VM cartridge constantly to print. And it didn’t let me clean it either. I did the following:
- Init Fill with piezo flush on VM channel and K7 ink on others
- Nozzle test print - First time, VM solved, few dots missing on Y
- Redid a test print - O, Y, VLM missing lines
- Cleaning
- Nozzle test print - O, Y, VLM blank
- Maintenance cleaning (dampers, heads, capping station)
- Nozzle test print - O, Y, VLM blank
- Launch a large test print - Piezoflush on the print (excepted as VM channel is piezo), no ink where Y, VLM supposed to lay ink
- Another Init Fill will all K7 ink
- Nozzle test print - same result (O, Y, VLM) - totally blank (no ink)
Any suggestions on what to do next? Thanks for the advice.
