Ink Cartridges
* The print capacity may vary depending on how often you use the
print head cleaning function. Also, if you print large graphics and
dense text with little white space, you use ink faster.
** The ink thaws and is usable after approximately 3 hours at 77 °F
(25 °C).
Caution:
To ensure good results, use genuine EPSON cartridges and do not
refill them. Other products may cause damage to your printer not
covered by EPSON’s warranty. Do not use an ink cartridge after the
expiration date on the package.

Control Panel
Follow these guidelines when the control panel lights come on
or flash:
Testing the Printer
You can run a self test to determine whether the problem
comes from the printer itself or some other source.
❏If the results are satisfactory, the problem lies in your
software settings, the network and configuration, or your
computer.
❏If the self test does not print correctly, you have a problem
with your printer.
Follow these steps to run the test:
1. Make sure both the printer and computer are turned off.
2. Disconnect the network cable from the printer.
3. Make sure paper is loaded in the printer.
Caution:
Load paper that’s at least 8.27 inches (210 mm) wide. This
prevents ink from spraying inside the printer and smudging your
printouts.

5. To end the test, turn off the printer. Then reconnect the
network cable and turn on your printer and computer.
Using Hex Dump Mode
You can use the printer’s hex dump mode to identify problems
if you know how to interpret hex code. Follow these steps:
1. Make sure the printer is turned off and has paper loaded
in it.
2. Open the cover.
3. Hold down the
Eload/eject button and the Xcolor
cleaning button and press the
Ppower button. The printer
prints Hex Dump Mode at the top of a page and then

4. Print one or more pages from an application as usual. The
printer prints the exact code it receives in hexadecimal
format.
5. Turn off the printer to exit hex dump mode.
Printing an Ethernet Card Status
Sheet
You can print a status sheet to see information about your

network information. You need the status sheet information
to configure your card. Follow these steps:
1. Make sure the printer is turned on and has paper in the
feeder.
2. Press the status sheet button and hold it for about three
seconds to print out the status sheet.
Reading the Ethernet Card Status
Lights
The status lights on the Ethernet card plate provide you with
the basic printer and network status.
The red and green status lights indicate the following:
Initializing the Ethernet Card
You only need to initialize the card under the following
conditions:
❏The first time you connect the printer to a network
❏If there is an error communicating with the Ethernet card
❏When you reinstall the card in a different printer
Follow these steps to initialize the Ethernet card:
1. Turn off the printer.
It will take several seconds for the Ethernet card to power
down. Wait until the status lights on the card go out before
continuing to step 2.
2. Turn on the printer while pressing and holding down the
status sheet button for about five seconds.
When the red and green status lights start to flash
simultaneously, stop pressing the status sheet button.
Initialization is complete when the status lights stop
flashing.
3. After initialization is complete, press the status sheet button
and hold it for about three seconds to print a status sheet. If
the card initialized, the IP address reads 11.22.33.44.
Note:
You can also initialize the Ethernet card using its internal home page.

Resetting the Ethernet Card

condition, you may be able to correct it by resetting the
printer memory. Press the
Ppower button. After the lights
on the card go out, press the button again.
Installing Ink Cartridges for the
First Time
Always use the ink cartridges that came in the box the first
time you set up the printer. Follow these steps to install the
ink cartridges:
1. Make sure the printer is turned off (the
Ppower button
should be up). Then plug the printer’s power cord into a
grounded outlet.
Caution:
Always use the
Ppower button to turn the printer on or off. Never
use an external switch—such as a power strip switch—to turn off
the printer.
Don’t use an outlet that can be turned off by a wall switch or timer,
or one that uses the same circuit as a large appliance. This may
disrupt the power, which can erase memory or even damage the
printer’s power supply.
2. Remove the ink cartridges from their foil packages. Then
remove only the yellow part of the tape seal on the top of
each one. Don’t pull off the white portion or try to remove
the clear seal underneath the cartridge.
Caution:
To ensure the print heads charge correctly, install the ink cartridges
that came with the printer.
You must remove the yellow tape from the top of the cartridge or
you will permanently damage it. It’s OK if a small corner of the
yellow tape stays on the cartridge.
Warning:
If ink gets on your hands, wash them thoroughly with soap and
water. If ink gets in your eyes, flush them immediately with water.
3. Press the
Ppower button to turn on the printer. The
Ppower light flashes and the B black and A color ink out
lights come on. The black ink cartridge holder moves into
loading position.
4. Open the printer cover and lift up the black ink cartridge
clamp.
5. Place the black ink cartridge in the holder with the label
pointing up and the arrow pointing to the back of the
printer. Then close the clamp, making sure it clicks into
place.

Caution:
If the ink cartridge holder moves back to the right before you install
the cartridge, don’t try moving it back by hand. Press the
Yblack
cleaning button and hold it down for 3 seconds to move the holder
back into position.
6. Now press the
X color cleaning button to move the color
ink cartridge holder into loading position.
7. Repeat steps 4 and 5 to install the color ink cartridge. Then
press the
E load/eject button to begin charging the ink
delivery system.
Charging takes up to 4 minutes. The
Ppower light flashes
and the printer makes various sounds until it’s finished.
Don’t turn off the printer or interrupt the charging process
or it will start over, using more ink than necessary.
Caution:
Never turn off the printer when the
Ppower light is flashing,
unless the printer hasn’t moved or made any noise for more
than 10 minutes.
Removing and Installing an Ink
Cartridge
When the
Bblack or Acolor ink out light flashes, the
indicated cartridge is low on ink. This is a good time to make
sure you have a new cartridge. When the light stays on, the
cartridge is empty and you need to replace it.
Use these EPSON ink cartridges within six months of
installing them and before the expiration date on the package:
Black ink cartridge: S020108
Color ink cartridge: S020089
When you need new ink cartridges, contact your dealer or call
EPSON Accessories at [phone] (U.S. only). In
Canada, please call [phone] for dealer referral. Or visit
our website at www.epsonsupplies.com.
When the
Acolor ink out light comes on, you can continue
to print with black ink. Simply turn the printer off and then
back on again. When you print, make sure you choose Black
as the Ink setting in your printer software.
Removing an Empty Ink Cartridge
You can replace a cartridge when the
Bblack or Acolor ink
out light is either flashing or on. Make sure the printer is
turned on and not printing before you start. Determine which
ink cartridge needs to be replaced, then follow these steps:
1. Lower the output tray and raise the printer cover.
2. Press the
Yblack or Xcolor cleaning button and hold it for
three seconds.
Caution:
If you press a cleaning button when no ink out light is flashing or
on, the printer cleans the print heads, as described on page 11. If
you need to replace an ink cartridge before the lights flash (because
the ink is too old, for example), follow the instructions under
“Replacing an Outdated Ink Cartridge” on page 10.
The print heads move slightly left and the
Ppower light
begins flashing. (The print heads return to their home
position if you don’t proceed to step 4 within 60 seconds.)
Caution:
To avoid damaging the printer, never move the print heads by hand.
3. Pull up the ink cartridge clamp. The cartridge rises up from
its holder. (Although the illustration shows the black ink
cartridge, the procedure is the same for replacing the color
ink cartridge.)

Caution:
Don’t open the clamp or remove a cartridge except to replace it
with a new one. Once you remove a cartridge, you can’t reuse it,
even if it contains ink.
4. Lift the cartridge out of the printer and dispose of it
carefully.
Warning:
If ink gets on your hands, wash them thoroughly with soap and
water. If ink gets into your eyes, flush them immediately with
water.
5. Follow the steps in the next section to install the new ink
cartridge.
Installing the New Cartridge
Once you have removed the empty cartridge, you’re ready to
install the new one. Follow these steps:
1. Remove the new ink cartridge from its packaging.
2. Remove only the yellow part of the tape seal on top as
shown below. Don’t pull off the white portion or try to
remove the clear seal underneath the cartridge.
Caution:
You must remove the yellow tape from the top of the cartridge or
you will permanently damage it. It’s OK if the tape does not tear off
completely along its dotted line. Do not remove the clear seal from
the bottom of the cartridge; ink will leak out.
3. Lower the ink cartridge into its holder with the label facing
up and the arrow pointing to the back of the printer.
4. Press down the ink cartridge clamp until it locks in place.
5. If you need to replace the other ink cartridge, follow the
steps under “Removing an Empty Ink Cartridge,” and then
steps 1 through 4 under “Installing the New Cartridge.”
6. Press the
Eload/eject button and close the printer cover.
The printer moves the print heads and begins charging the
ink delivery system. (Even if you don’t press the button, ink
charging begins 60 seconds after you close the clamp.)
The
Ppower light flashes, and the printer makes various
sounds. Charging takes about three minutes. When it’s
finished, you can print again.
Caution:
Never turn off the printer when the
Ppower light is flashing,
unless the printer hasn’t moved or made any noise for more than
10 minutes.
Replacing an Outdated Ink Cartridge
If an ink cartridge is more than six months old, you may need
to replace it. How can you tell? You may notice that your
printouts don’t look as good as they used to. If print quality
doesn’t improve after cleaning and aligning the print heads,
you can replace one or both cartridges.
Follow these steps to replace an ink cartridge before the
Bblack or Acolor ink out light is flashing or on:
1. Make sure the printer is turned on and not printing.

2. Lower the output tray and raise the printer cover. Then
locate the
Yblack and Xcolor cleaning buttons next to the
control panel under the printer’s cover.
Caution:
To avoid damaging the printer, never move the print heads by hand.
3. Press both the
Yblack and Xcolor cleaning buttons and
hold them down for a few seconds until the black print head
moves to the left.
❏To replace the black ink cartridge, follow the
instructions beginning with step 3 of “Removing an
Empty Ink Cartridge” on page 9.
❏To replace the color ink cartridge, press the
Xcolor
cleaning button and hold it down for a few seconds.
After the color ink cartridge moves to the left, follow the
instructions beginning with step 3 of “Removing an
Empty Ink Cartridge” on page 9.
Cleaning the Print Heads
If your printed image is unexpectedly light or faint, or dots are
missing from the image, you may need to clean the print
heads. This unclogs the nozzles so they can deliver ink
properly.
Cleaning the print heads uses ink, so clean them only if print
quality declines. You can clean the print heads in either of the
following ways:
❏With the Head Cleaning utility in your printer software
(when you have installed Status Monitor 2)
❏Using the printer’s control panel buttons
Using the Head Cleaning Utility
Follow these steps to run the utility from a Windows
computer or a Macintosh:
1. Make sure the printer is turned on but not printing, and the
Bblack and Acolor ink out lights are off.
2. Access the printer settings dialog box.
3. Click the Utility tab (Windows) or the Utility button
(Macintosh). You see the Utility menu.
4. Click the Head Cleaning button.
5. Follow the instructions on the screen to clean one or
both print heads. Cleaning each head takes about two
minutes, during which the printer makes some noise and
the
Ppower light flashes.
When the power light stops flashing, you need to run a
nozzle check to test the print quality and reset the cleaning
cycle.
Caution:
Never turn off the printer when the
Ppower light is flashing,
unless the printer hasn’t moved or made any noise for more than
10 minutes.
6. Make sure paper is loaded in the printer and click Print
nozzle check pattern (Windows) or Confirmation
(Macintosh). Then click Next. See “Examining the Nozzle
Check Pattern” on page 12 for instructions.
If your print quality has not improved, repeat the steps above.
If you don’t notice any improvement after doing this two or
three times, check the print quality solutions in the User’s
Guide.
Using the Control Panel
Follow these steps to clean the print heads:
1. Make sure the printer is turned on and not printing, and
that the
Bblack and Acolor ink out lights are off.
2. Open the printer cover, then press the
Yblack or Xcolor
cleaning button and hold it for three seconds. Cleaning
takes about two minutes, during which the printer makes
some noise and the
Ppower light flashes.
3. When the
Ppower light stops flashing, repeat step 2 for the
other print head if necessary.
Caution:
Never turn off the printer when the
Ppower light is flashing,
unless the printer hasn’t moved or made any noise for more than
10 minutes.
4. After you’re finished cleaning and the
Ppower light stops
flashing, you need to print a page to test the print quality
and reset the cleaning cycle. If you’re connected directly to
the printer, run a nozzle check. Go to step 5.
If you’re using DOS or you didn’t install Status Monitor 2,
open an application and print a document containing black
and color data. Then go to step 7.
5. Access the printer settings dialog box. Then click the
Utility tab (Windows) or the Utility button (Macintosh).
You see the Utility menu.
6. Click the Nozzle Check icon, then click Next. See the
next section for instructions on examining the nozzle check
pattern.
7. If your print quality has not improved, repeat the steps
above. If you don’t notice any improvement after doing this
two or three times, check the print quality solutions in the
User’s Guide.

Examining the Nozzle Check Pattern
Examine the nozzle check pattern you print. It should look
something like this, with the lower pattern colored cyan,
magenta, and yellow:
Each staggered horizontal and straight vertical line should be
complete, with no gaps in the dot pattern. If your printout
looks okay, you’re done. If any dots are missing, as illustrated
below, clean the print heads again.
Aligning the Print Heads
If your printouts contain misaligned vertical lines, you may
need to align the print heads. You can align the print heads in
either of the following ways:
❏With the Print Head Alignment utility in your printer
software (when you have installed Status Monitor 2)
❏Using the printer’s control panel buttons
Using the Print Head Alignment Utility
Follow these steps to run the utility (Windows or Macintosh):
1. Make sure the printer is turned on and paper is loaded.
Caution:
Load paper that’s at least 8.27 inches (210 mm) wide. This
prevents ink from spraying inside the printer and smudging your
printouts. For the best results, load EPSON ink jet paper to check
your alignment.
2. Access the printer settings dialog box.
3. Click the Utility tab (Windows) or the Utility button
(Macintosh). You see the Utility menu.
4. Click the Print Head Alignment icon.
5. Follow the instructions on the screen to print a test page
and select the correct alignment.
Using the Control Panel to Align the Print
Heads
Follow these steps to align the print heads:
1. Make sure the printer is turned off and paper is loaded.
Then open the printer cover.
Caution:
Load paper that’s at least 8.27 inches (210 mm) wide. This
prevents ink from spraying inside the printer and smudging your
printouts. For the best results, load EPSON ink jet paper to check
your alignment.
2. Hold down the
Eload/eject button and the Yblack cleaning
button and turn on the printer. Then release the buttons.
After a moment, the printer prints an instruction sheet
telling you how to select a language for the alignment
instructions.
3. Press the correct control panel buttons as instructed to select
a language. The printer prints instructions for aligning the
print heads.
4. Follow the instructions on the sheet to align the print heads.
When you’re finished, turn off the printer to exit the
alignment mode.
Using Special Media
When you print on special media, you need to be careful
about choosing the correct Media Type and Paper Size
settings in your printer software. The table on the following
page lists the available EPSON media and the corresponding
Media Type setting for each one in your printer software.

Transporting the Printer
If you need to transport your printer some distance, you
should repack it in its original box. Follow these steps:
1. Turn on the printer and wait until the print heads lock in
the far right position. Then turn off the printer.
2. Unplug the power cord from the electrical outlet. Then
disconnect the network cable from the printer.
Caution:
To avoid damage, always leave the ink cartridges installed when
transporting the printer.
3. Remove any paper from the printer and remove the paper
support.
4. Push in the output tray extensions and close the tray.
5. Repack the printer and attachments in the original box
using the protective materials that came with it. See the
Notice Sheet that was packed with the printer.
Be sure to keep the printer level as you transport it. If you
move the printer to a new network, you should initialize its
Ethernet card so you can configure it for that network. If you
notice a decline in print quality after transporting the printer,
clean the print heads; if output is misaligned, align the print
heads.
