Why does the newly installed ink cartridge show low ink level?

With Canon printer's remanufactured ink cartridges, the printer shows that the ink level is low, press the printer's reset button for 5 seconds.

 When the HP printer shows that the ink level is empty, click Confirm to continue using it. If it does not affect the use, it can be ignored.

1. Rub the chip with an eraser. (May be chip memory delay)
2. Clean the print head. The remaining ink will affect the reading results.
3. Wrap the ink cartridge with tissue and shake.
