Loading Paper 3
Loading Paper
Epson offers a wide array of high quality papers, making it easy to maximize the impact of
your documents, photos, presentations, and other projects.
■ Load Epson
®
Premium Presentation Paper Matte or any type of Epson photo paper
only in the upper paper cassette (if your product has two cassettes).
■ Load paper printable side down; it is usually whiter or brighter.
■ Always load paper short edge first and make sure the edge guides are against the paper.
■ Make sure the paper is loaded against the edge guide and not sticking out from the
end of the cassette. The paper may slide forward slightly as you insert the cassette.
This is normal.
■ After you load paper, use the control panel to select the paper size and type.
■ For instructions on loading envelopes, legal-size paper, or using the rear paper feed
slot, see the online User’s Guide.

You can also check the basic troubleshooting suggestions below. For more in-depth
troubleshooting, see your online User’s Guide or access interactive troubleshooting and
FAQs at epson.com/support (U.S.) or epson.ca/support (Canada).
■ Try connecting to the wireless router or access point with your computer or another
device to confirm that it is working correctly.
■ Try restarting the router (turn it off and then on), then try to connect to it again.
■ Print a network status sheet from the product’s control panel. Press if necessary and
select
Setup > Network Status > Wi-Fi/Network Status. Then select Print and
press one of the x
buttons.
Verify that the network settings are correct and check the signal strength. If it is poor,
try moving the product closer to your router or access point. Avoid placing it next to a
microwave oven, 2.4 GHz cordless phone, or large metal object such as a filing
cabinet.
■ If your wireless router doesn’t broadcast its network name (SSID), manually enter
your wireless network name.
■ If your wireless router has security enabled, make sure you entered the WEP key or
WPA passphrase correctly.
■ When using TCP/IP, make sure your network’s DHCP option is enabled (your router
manufacturer will be able to assist you with this setting).
■ Remove and reinstall your product software.
■ Disable your computer’s firewall temporarily to see if that may be causing the
problem. Contact your firewall manufacturer for assistance.
