Epson WorkForce Pro WP-4023 Network Wireless Color Printer

The printer's lights will flash when one or more of the ink cartridges is low or expended. You may also see a message on your computer screen.

Note:
When an installed ink cartridge is more than six months old, you may need to replace it if your printouts do not look their best even after you clean and align the print head.
