With new cartridge indicates low ink level,

The ink level gauge may not work properly with refilled cartridges. Because of this, you might get low ink message after refilling. To install the refilled cartridge you might need to override the ink level gauge. Overriding the ink level gauge disables the printer’s ink level tracking feature, but allows you to use refilled cartridges. To override the ink level gauge, please check your printer reference guide. After disabling the ink level tracking feature you should check the ink level visually and as soon as the ink level gets low you need to refill the cartridge. You do not want to try to print with an empty cartridge. Trying to print with an empty cartridge may damage your print-heads.
