Checking Ink Levels 15

Checking Ink Levels

If an ink cartridge is expended, you see a message on your product’s

LCD screen:

Note: Printing stops when an ink cartridge is expended. If a color

cartridge is expended, you may be able to continue printing

temporarily with black ink; see the online User’s Guide for more

information. If the black cartridge is expended, you must replace it

to continue printing.

You can check ink cartridge levels by pressing if necessary and selecting F Setup, then

pressing

OK. Select Ink Levels and press OK. The ink levels displayed are approximate.

A window may also appear on your computer screen when you try to print when ink is

low. This window can optionally display ink offers and other updates from Epson.

Note: To disable checking for ink offers or updates from Epson, see the instructions in

your online User’s Guide.

Purchasing Epson Ink Cartridges and Paper

You can purchase genuine Epson ink and paper from Epson Supplies Central at

www.epson.com/ink3 (U.S. sales) or www.epson.ca (Canadian sales). You can also

purchase supplies from an Epson authorized reseller. To find the nearest one, call

800-GO-EPSON (800-463-7766).

Use the following list when you order or purchase new ink cartridges:

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 printer

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 cartridges included with the

printer are designed for printer setup and not for resale. After some ink is used for

priming, the rest is available for printing.

For best printing results, use up a cartridge within six months of opening the package,

and before the expiration date on the cartridge box.
