The inking method for portable printers mainly involves the following steps:

　　Ensure that the printer is turned on and the ink cartridge will automatically move to the middle position.

　　Open the ink cartridge compartment cover and gently remove the ink cartridge, being careful not to touch the chip on the side of the ink cartridge.

　　For ink cartridges that require ink, use a funnel or syringe to inject ink into the corresponding color area of the cartridge, being careful not to fill it too much and leaving some space to prevent ink from overflowing.

　　Wipe the copper contacts at the bottom of the ink cartridge with a tissue or cloth to ensure cleanliness and prevent poor contact.

　　Follow the reverse steps of disassembly to reinstall the ink cartridge into the printer and close the ink cartridge compartment cover to ensure it is locked in place.

　　Turn on the printer power and perform initialization cleaning to ensure printing quality.

　　For portable thermal printers, the ink adding process may be slightly different, and the specific steps need to refer to the user manual of the printer model. During the inking process, it is important to avoid moving or shaking the printer while it is in operation to avoid affecting the printing quality. In addition, regularly cleaning the printer's nozzle to prevent ink blockage is also an important step to ensure the normal use of the printer.
