Solutions
Remove any paper or protective material in the printer. If the error
message is still displayed, contact Epson support.
Load paper, and then insert the paper cassette all the way.
To ensure you receive premium print quality and to help protect your
print head, a variable ink safety reserve remains in the cartridge when
your printer indicates it is time to replace the cartridge. Replace the
cartridge when you are prompted to do so.
If Paper Setup Auto Display is disabled, you cannot use AirPrint.
This problem might be resolved by selecting Settings > General
Settings > Fax Settings > Basic Settings > Line Type and then
selecting PBX. If your phone system requires an external access code to
get an outside line, set the access code after selecting PBX. Use # (hash)
instead of the actual access code when entering an outside fax number.
This makes connection more secure.
If the error message is still displayed, set the Dial Tone Detection
settings to disabled. However, disabling this feature may drop the first
digit of a fax number and send the fax to the wrong number.
Enter the correct IP address or default gateway. Contact the person who
setup the network for assistance.
Run Web Config, and then update the root certificate.
Make sure the printer port is selected correctly in Property > Port from
the Printer menu as follows.
Select "USBXXX" for a USB connection, or "EpsonNet Print Port" for a
network connection.
