This error typically indicates one of the inks is not inserted properly. Check out the link below for a few things you can try. Hope this helps!
If the issue persists, please reach out to our technical support through the link below:
To try and remove the inks, please turn off the printer, unplug the power cord from the back and then, gently with your finger, try to move the ink cartridge holder over so that you can remove the ink cartridges. If the ink cartridge holder does not move over easily, please do not force it, as this can do damage to the printer. Once the ink cartridges are removed, you can then plug the printer back in and turn it on, then reinsert the ink cartridges.
If the error still occurs after reseating the ink cartridges, or if you are unable to remove the cartridges, the printer will require servicing. Please Contact Us for your servicing options.
