Replacing Ink Cartridges - Epson WorkForce 840 Quick Manual

Use the following list when you order or purchase new ink cartridges:
Ink color
Black
Cyan
Magenta
Yellow
Note:
We recommend that you use genuine Epson cartridges and do not refill them. The use
of other products may affect your print quality and could result in product damage.
Yields vary considerably based on images printed, print settings, paper type, frequency
of use, and temperature. For print quality, a small amount of ink remains in the cartridge
after the "replace cartridge" indicator comes on. The product ships with full cartridges
and part of the ink from the first cartridges is used for priming the product.
For best printing results, use up a cartridge within six months of opening the package
and before the expiration date on the cartridge box.
Store ink cartridges in a cool, dark place. If cartridges have been exposed to cold
temperatures, allow them to warm up to room temperature for at least 3 hours before
using them.

Replacing Ink Cartridges

Make sure you have a new ink cartridge before you begin.
Caution:
Do not open ink cartridge packages until you are ready to install the ink. Cartridges are
vacuum packed to maintain reliability.
Leave the expended cartridge installed until you have obtained a replacement, or the
ink remaining in the print head nozzles may dry out.
1. Turn on the product.
2. If an ink cartridge is low or expended, you see a
message on the LCD screen indicating which
color to replace. Press
