Different manufacturers’ printhead cleaning liquids vary in composition depending on what they are designed to clean. Some may contain conductive particles, and suppliers may not disclose all ingredients to protect proprietary formulas.
If the printhead isn’t completely dry before reinstalling, leftover liquid can create short circuits, damaging the printhead and potentially the printer’s motherboard. This happens because the conductive residue can carry electricity along unintended paths inside the head.
Recommendations:
Dilute concentrated cleaning liquids with distilled water, not tap water, to avoid corrosion and conductivity issues.
Always let the printhead air dry completely before reinstalling it in the printer.
