Làm thế nào để làm sạch đầu máy in phun

Nếu một máy in đã không được sử dụng trong một thời gian dài, the many tiny holes that make up a modern inkjet printer’s head may become clogged with dried ink.Your printer can serve you for a longer duration of time without exhibiting a drop in print quality if you clean and maintain it on a regular basis.

Here are some ways to manually clean inkjet printheads:

• Determine from the owner’s manual where the print head is located.
• Remove the ink cartridge from your printer and then dip a foam swab in hot water or isopropyl alcohol and rub it against the print head. This should loosen any crusted ink. NOTE: Be careful, especially if you use isopropyl alcohol to clean your print heads: Some printers use rubber gaskets, and if you get isopropyl alcohol on the gaskets it could dry them out.
• For models where the print head is in the printer, drop 7 to 10 drops of isopropyl alcohol (91% denatured isopropyl alcohol – not ‘rubbing’ alcohol) down the ink receptacle area where the ink actually flows from the cartridge into the head. Run a few self-cleaning utilities. If possible, allow the printer to sit a few hours or overnight and repeat the self-cleaning utility.
• If the print head is in the cartridge, soak the cartridge print head in hot water. Allow it to soak overnight. Dry the print head area with a paper towel. Repeat the self-cleaning utility.
• If the hot water soak did not unclog the print head, place the cartridge printer head in isopropyl alcohol and allow it to soak overnight. Use a damp paper towel to wipe off the print head area and dry carefully. Try the self-cleaning utility again.
• If the alcohol soak did not unclog the print head in the cartridge you may need to purchase a new cartridge. This will provide new print heads that won’t be clogged. Contact a service technician for repair of print heads in the printer if the alcohol did not unclog the printer head.
