How does the printer cleaning pen use it?
The printer used for a long time, because the head of the print head toner residue
caused by the printing effect is not very good, a direct impact on the use of thermal printers
So we often use the
printer cleaning pen to clean the head of the printer
1, disconnect the power to ensure safety.
2, open the printer, find the location of the print head.
4, so that the pen tip and the print head smooth contact, in the print head back and forth to erase. (Clean pen head is IPA solution, with good volatility, do not worry about the liquid residue in the print head)
5, turn on the power, test how the cleaning effect, if not clear, repeat the above steps, clean again.
