If you encounter an error message stating that "The following ink tank(s) cannot be recognized" (Figure 1), please try the following steps as possible solutions to resolve the problem.
Firstly, remove the cartridge that caused the error from the cradle. When you open the printer lid, you will see that the cartridge that is not being recognized does not have a red light in front of it. Gently push out on the tab on the front of the cartridge. Reinstall the ink cartridge (Figure 2) and you should hear it "click" into place. If the ink cartridge is still not being recognized, remove the ink cartridge from the cradle again. Confirm that there is a chip intact and in the correct location.
If the chip is missing (Figure 3), you should return the cartridge to the place of purchase. If the chip is in place, you may need to clear it from any kind of obstruction or debris as this could be the cause of the error.
To clean the chip, you can use a pencil eraser. Brush the chip lightly with the eraser to remove any potential obstruction or debris. Or you can use any type of lint free cloth to gently wipe the chip (Figure 4), again to remove any type of obstruction or debris. Once this is complete, replace the ink cartridge in the cradle. If the problem persists, you need to reset the printer. This can be done by turning off the computer and the printer with the cartridge installed. Unplug your printer and let your machines off for 2 minutes. Restart the printer and computer, and try printing again. If you tried both steps and got the same error, there is most likely an electrical problem with the cartridge and you should return the cartridge to where you purchased it.
