What does it mean when my product's control panel lights flash or remain on solid?

• If the Ink Out light flashes, the printer is getting low on ink; if it is on solid, the printer is completely out of ink and you need to replace the cartridge; if it is flashing rapidly, the printer detected a print head unit or ink cartridge installation error. If the Paper Out light is on solid, you need to install paper in the printer; if it is flashing, the printer detected a paper jam. When both the Ink Out and Paper Out lights are on solid, the printer thinks that there is a carriage error; if both lights are flashing, there is a fatal error and the printer will need to be sent in for service.
