Soft clog repair: (1) Soft clogs are caused by increased ink viscosity at the nozzle due to various factors. Sometimes, residue is only on the nozzle surface and can be cleared by soaking in original ink and cleaning multiple times. (2) Use the print head cleaning function in the printer drivers utility tool to clean. 2. Hard clog repair: (1) Soaking method for light clogs: Place the print head in a container with 95% organic solvent alcohol, ensuring the alcohol covers the stainless steel edge but does not contact the PCB board. Soak for 2 hours to 4 days. (2) 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 a tight seal). Submerge the print head outlet in 95% organic solvent alcohol and gently draw alcohol through the nozzles several times. This method provides effective cleaning. Apply steady, even pressure to avoid damage. Requires manual assembly of tools and may require technical skill for best results. Properly constructed tools can be reused.
