Add 95% organic solvent alcohol to cover the stainless steel edge of the print head, avoiding contact with the PCB board. - Soak for 2 hours to 4 days. - Pressure cleaning method (for severe clogs): - Use a plastic tube or needle from a disposable infusion set to connect a syringe to the ink supply port (ensure tight seal). - Submerge the print head outlet in 95% organic solvent alcohol and gently draw alcohol through the nozzle using the syringe (inhalation only). - Repeat several times. This method generally clears most clogs. - Apply steady, even pressure to avoid damage. - Requires manual assembly of tools and basic technical skill. Properly made tools can be reused.
