Please try to confirm if the nozzle is clogged by doing the following:
- Remove the cartridge(s) from the printhead(s) without removing the air pressure hose.
- Remove the nozzle and replace it with a new one of the same type
- Carefully place the cartridge(s) back into the printhead(s)
If the issue persists, please contact CELLINK support at firstname.lastname@example.org .
