Epson WorkForce Pro WP-4090 User Manual page 117

Caution: Leave your old cartridges in the printer until you are ready to replace them to prevent the print
head nozzles from drying out. Do not open ink cartridge packages until you are ready to install the ink.
Cartridges are vacuum packed to maintain reliability.
1. Turn on your product.
2. Note which cartridges need to be replaced.
3. Open the front cover.
4. Push the ink cartridge in, then pull it out of the slot.
Note: Dispose of used cartridges carefully. Do not take the used cartridge apart or try to refill it.
Warning: If ink gets on your skin, wash it thoroughly with soap and water. If ink gets into your eyes,
flush them immediately with water. If ink gets into your mouth, spit it out and see a doctor right away.
Keep ink cartridges out of the reach of children.
