Printhead damage caused by improper cleaning liquid usage

Different manufacturers' printhead cleaning liquids have varying compositions, depending on the materials they are designed to clean and their intended purpose. In some cases, suppliers may not disclose all ingredients in their MSDS (Material Safety Data Sheets) to protect their proprietary formula from being counterfeited. Some cleaning liquids may contain conductive particles, making them capable of conducting electricity.

For this reason, when you clean your printhead with those kinds of liquids, you have to let the printhead dry completely. If the printhead has not fully dried and there is a residue of such liquid inside the head and you put the printhead back into the printer and turn the power on, a partial short could occur inside the printhead. This can occur because the chemical liquid residue will attract the current to unwanted paths inside the head, damaging the head components and most likely damaging the mother board (the main printer circuit board) as well.

We recommend using distilled water to dilute the concentrated cleaning liquid, as it has low conductivity. Ensure the printhead is thoroughly dried before reinstallation. Avoid using tap water, as it has higher conductivity and can deposit particles that may gradually corrode the printhead.
