I removed the white label from the top of one of my ink cartridges. What should I do?

• Do not install the cartridge. If you have already installed it and the printer is printing correctly, change the cartridge immediately. If you have already installed the cartridge, or if a previously installed ink cartridge was missing its EPSON label at the time it was installed, and now the nozzle check will not print completely even after running cleaning cycles, your printer may need service and you should call the EPSON Connection for further assistance.
