Ink cartridge filling and precautions

Problems that are often overlooked - error padding

  • The sponge structure of the original ink cartridge can only be used with "low pressure" when filling.
  • Insert the filling needle at the end of the syringe or ink bottle. The filling speed should not be too fast. When the high-speed injection ink comes into contact with the ink sponge, the ink will generate a lot of bubbles. The ink cannot be stored in the sponge, and the ink filled in the ink cartridge. It may overflow from the top or leak out from the nozzle.

The internal structure of the original ink cartridge

  • Please refer to the US Patent Document No. US009452609.
  • HP 564 SETUP,564 Standard,564XL ink cartridges are different, and the filling method of each type of ink cartridges is different.
  • According to the type of ink cartridge, when filling the ink cartridge, you need to select the correct filling tool to fill your ink cartridge effectively.
