Installing an Ink Cartridge for the First Time
1. Plug the power cord into a grounded outlet.
Caution:
Don’t use an outlet controlled 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 the
printer’s memory or damage its power supply.
2. Remove the ink cartridges from their foil packages. Then
pull off only the yellow part of the tape seal on the top of
each cartridge. It is okay if a bit of the yellow tape remains
on the cartridge. Do not pull off the blue part.
Caution:
You must remove the yellow tape seal from the top of
the cartridge or you will permanently damage it. Don’t
remove the tape seal from the bottom.

5. Pull up the two ink cartridge clamps.
6. Insert the ink cartridges into their holders with the blue
labels facing up and toward the back of the printer.

Testing the Printer
You can run a printer check to determine whether a problem
comes from the printer itself or some other source.
❏ If the results are satisfactory, the problem lies in software
settings, the interface cable, or your computer.
❏ If the printer check does not print correctly, there is a
problem with your printer.
Follow these steps to check the printer:
1. Make sure both the printer and computer are turned off.
2. Disconnect the interface cable from the printer.
3. Make sure paper is loaded in the printer.
4. Hold down the
button. Hold down the buttons until the
starts to flash. Then release both buttons.
The printer prints one page containing the printer’s ROM
version, ink counter code, and a nozzle check pattern. Only
the nozzle check pattern is shown below:
5. After it prints the page, turn off the printer. Remember to
reconnect the interface cable, then turn on the printer and
your computer.

Note:
If you need to replace an ink cartridge before the lights flash (because
the ink is too old, for example) follow the instructions in “Replacing
an Outdated Ink Cartridge” on page 9.
When you need new ink cartridges, contact your dealer or call
EPSON Accessories at (800) 873-7766 (U.S. sales only). In

Removing an Empty Ink Cartridge
Note:
If you press the
flashing or on, the printer cleans the print head (see “Cleaning the
Print Head”).
You can replace a cartridge when the B black or A color ink
out light is either flashing or on. Follow these steps:
1. Make sure the printer is turned on and not printing.
2. Lower the output tray and raise the printer cover.
R
cleaning button when neither ink out light is
Caution:
Never move the print head by hand.
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.
❏ If the special media has protective sheets between each sheet
of media, be sure to remove the protective sheets before
printing.
Replacing an Ink Cartridge
When a B black or A color 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. You cannot print if either
ink cartridge is empty.
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.
Use these EPSON ink cartridges within six months of
installing them and before the expiration date on the package:
❏ Black ink cartridge: S020187
❏ Color ink cartridge: S020191
3. Press the R cleaning button and hold it for three seconds.
The print head moves slightly to the left and the
Ppower
light begins flashing.
4. Pull up the ink cartridge clamp. The cartridge rises up from
its holder.
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. Lift the cartridge out of the printer and dispose of it
carefully.
6. 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 package.
Caution:
You must remove only the yellow tape seal from the top
of the cartridge; leaving the tape on will permanently
damage it. Do not remove the clear seal from the bottom
of the cartridge; ink will leak.
2. Remove only the yellow part of the tape seal on the top of
the cartridge. Do not remove the blue label. (It’s okay if a
bit of the yellow tape does not tear off.)

3. Lower the ink cartridge into its holder with the blue label
facing up and toward the back of the printer.
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 head, try
replacing one or both cartridges.
Follow these steps to replace an ink cartridge before the
B black or A color 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.
Caution:
To avoid damaging the printer, never move the print head
by hand.
3. Press the E load/eject button and hold it down for a few
seconds until the print head moves to the left.
4. Pull up the ink cartridge clamp. The cartridge rises up from
its holder.
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. Lift the cartridge out of the printer and dispose of it
carefully.
6. Remove the new ink cartridge from its packaging.
4. Press down the ink cartridge clamp until it locks in place.
5. If you need to replace the other ink cartridge, remove it as
described in “Removing an Empty Ink Cartridge” on
page 8. Then follow steps 1 through 4 in this section.

Cleaning the Print Head
If your printed image is unexpectedly light or faint, or dots are
missing from the image, you may need to clean the print head.
This unclogs the nozzles so they can deliver ink properly.
Caution:
Don’t use the cleaning sheets that may be included with
your special media; they may damage the printer.
Cleaning the print head uses ink, so clean it only if print
quality declines. You can use either of the following to clean
the print head:
❏ The Head Cleaning utility in your printer software (if the
printer is on a local port rather than a network)
❏ The printer’s control panel buttons.
Using the Head Cleaning Utility
Follow these steps to run the utility:
1. Make sure the printer is turned on but not printing, and
that the

cleaning the print head.

Cleaning the Printer
Caution:
Don’t touch the gears inside the printer.
Never use alcohol or thinner for cleaning; they can
damage the printer components and case.
Transporting the Printer
If you want to move your printer some distance, you need to
prepare it for transportation and repack it in the original box.
Caution:
To avoid damage, always leave the ink cartridges
installed when transporting the printer.
Follow these steps:
1. Turn on the printer and wait until the print head locks in
the far right position. Then turn off the printer.
2. Unplug the power cord from the electrical outlet. Then
disconnect the interface cable from the printer.
3. Remove any paper from the sheet feeder 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
Unpacking Sheet that was packed with the printer.
Be sure to keep the printer flat as you transport it. If you
notice a decline in print quality after transporting the printer,
clean the print head; if output is misaligned, align the print
head.
Don’t get water on the printer components.
Don’t spray lubricants or oils inside the printer.
To keep your printer working at its best, you should clean it
several times a year, following these steps:
1. Turn off the printer, unplug the power cord, and
disconnect the printer cable.
2. Remove all the paper from the sheet feeder.
3. Clean the exterior of the printer with a soft, damp cloth.
Keep the printer cover closed so water doesn’t get inside.
