Clogged nozzles - Epson printers
Epson printers have a built-in, permanent printhead. While this allows Epson to use
a very high quality printhead, anyone who has replaced the printhead after warranty found out real quick that a
new printhead cost more than a new printer!
Whether you use original Epson cartridges, compatible Epson cartridges or refill your
cartridges, there WILL come a day when a few or even many nozzles will be blocked and the cleaning cycles will
not solve the problem. The fact is, if you run any more
than two or three cleaning cycles, the problem will just get worse.
Prevention:
There are several ways to help prevent clogged nozzles in Epson printheads.
NEVER RUN MORE THAN 3 CLEANING CYCLES
The printhead cleaning cycles on models of Epson printers has consistently gotten longer
with each new model introduced to the market. These longer cleaning cycles suck out more ink in an attempt to clear
the clog. Unfortunately, after two or three cleaning cycles, excess amounts of ink is being smeared over the printhead
and can actually block more or all of the nozzles. The more you clean, the more ink, the more smearing.
If after two cleanings the nozzles aren't cleared, then print at least 10 full pages.
If the nozzles don't clear themselves within these 10 pages, then further cleanings will not solve your problem.
You will have to manually clean the printheads. See several methods below.
ALWAYS TURN YOUR PRINTER OFF AT NIGHT
The Epson printers do a "mini-cleaning cycle" when the printer is first turned
on. This is to get the ink flowing through the printhead after it has been unused for a while. If you never turn
the printer off, then these mini-cleaning cycles to not take place.
PRINT ON A REGULAR BASIS
You should print several, full color pages AT LEAST ONCE A WEEK! This will help keep
the ink from drying out on the printhead or in the nozzles. Seldom used inkjet printers (all brands) cause more
problems than those which are used on a daily basis.
USE ONLY THE HIGHEST QUALITY CARTRIDGES AND REFILL KITS!
The printheads in Epson printers are a very precision made component. Many companies
want you to believe that "one ink does all printers". This is simply not possible. While this type of
refill kit may work with many printers, Epson owners simply should not take the risk. As models are introduced
the ink changes. This is the reason printer manufacturers are continually introducing new inkjet cartridges when
they introduce new printers. Higher resolutions and faster printing speeds require ink with very specific characteristics.
You may have been able to get away with "one refill kit does all" back 5 years ago, that certainly isn't
the case today!
The few $$$ you save by buying cheap refill kits and compatible cartridges WILL come
back and haunt you.
Methods to manually clean Epson printheads:
We suggest you perform the suggested methods of manually cleaning the Epson printheads
in the order they are listed below. They are listed in order from the easiest to the more difficult. If the first
method does not completely solve the problem, then go on to the next.
Distilled water or printhead cleaner in sponges
When the Epson printhead is in its resting or 'off' position, the printheads are above
a single or two sponges. By saturating these sponges often excess ink on the printheads will mix with the water
and get sucked into the sponge when the printer is turned on.
Move printhead assembly to centre of printer:
Start with the printer turned off. Open top of printer so you can see the printhead/cartridge
assembly. On older models of Epson printers you can simply move this assembly to the left, towards the centre of
the printer. Newer models have a locking lever which prevents the printhead assembly from moving from the resting
position. If you look closely, you should see a small, plastic (usually black or white) lever which comes up whenever
the printer stops printing. The lever to which we are referring is just left of the printhead assembly. This lever
can be moved forward and down easily with your finger. If you can't see the lever, then print a page with the top
open. Watch for a lever that goes down when it starts printing and then goes up after it has stopped.
With the printer off and the lever moved down as far as it will go, gently push the
printhead/cartridge assembly to the right. It will only move a fraction of an inch, but you should hear a click.
This is a second lock being released. The printhead assembly should now easily move to the left towards the centre
of the printer.
Saturate sponge(s):
With the printhead moved, you can now see the sponges which were under the printheads.
Take a syringe or eyedropper and saturate the sponge(s). Fill the sponge holder as much as you can. Use distilled water or InkMagic
printhead cleaner. Regular water will work, but it is the last choice. Move the
printhead assembly back over the sponges ... as far to the right as it will go. Let
printer sit for at least 15 minutes before turning it 'on'. You may want to leave
it overnight.
Be certain the printhead assembly is as far to the right as it will go before turning
the printer 'on'. Print 6 or 8 pages of dense print or graphics if it is the color which is causing the problems.
If you still have clogged nozzles, then move on to the next suggestion.
Distilled water or printhead cleaner in ink port
Remove ink cartridge(s) from printer. On newer models you may have to hold one of the
buttons down for several seconds for the printheads to move to the centre. Refer to your printer manual.
With the cartridge(s) removed you will now be able to see the small cone shaped ink
tubes (ink ports) which take the ink from the cartridge to the printhead. Black has one cone and the color has
three. Using a syringe with blunt needle, put a few drops of InkMagic printhead cleaner or distilled water in the cone. We recommend putting
water or printhead cleaner only in the cone which sends ink to the printhead causing the problems. e.g. if it is
the yellow which has nozzles missing, then put water only in the yellow inkport. If you're not sure which color
is which, then look at the holes in the bottom of the color cartridge. Yellow is usually the color on the far right
with magenta (red) in the middle and cyan (blue) on the left.
Put the cartridge(s) back into the cartridge holder. Do nothing. Usually after a few
minutes the printer will automatically return the printhead assembly to its resting position. If any water or printhead
cleaner dripped into the printer, wipe it dry with a papertowel.
Print 6 or 8 pages of dense print or graphics if it is a color which is causing the
problems. If you still have clogged nozzles, then move on to the next suggestion.
Clean printhead with papertowels
Fold papertowel and dampen:
Be certain the printer is turned 'off'. Tear a single sheet of paper towel in half.
Fold the sheet in half several times until it is about 1/2 inch by whatever length the sheet started at. In other
words, you want to fold it so it is long and skinny, not square. Open the cover of the Epson printer. Along the
path which the printhead assembly travels when printing, you will see a rubber roller which moves the paper. (this
is like the paper roller in a typewriter). Put the paper towel on top of this rubber roller and use tape on each
end to secure it. Put a few drops of InkMagic printhead cleaner or distilled water near the middle of the papertowel.
Move printhead assembly over the papertowel and let it rest on top of the damp portion
of the papertowel. (See above for information on how to release the printhead assembly.)
We suggest letting the printhead sit over the paper towel for at least 15 minutes.
This will soften the ink on the printhead. Move printhead assembly back to its resting position. You will probably
notice that the papertowel now has one long black blob of ink on it. (There is so much excess ink on the printheads
that all the colors are mixing to make black.) If you cannot clearly see individual colors, then dampen another
spot on the paper towel and move the printhead back over the newly dampened spot on the papertowel. Continue repeating
this until you see all the individual colors. You may have to use several pieces of folded paper towels.
Before turning the printer 'on', be certain to move the printhead back to its resting
position and remove the papertowel from inside the printer. Now that all excess ink has been removed from the printheads,
your clogged nozzles should be cleared. It may take several pages of dense print to get the ink flowing properly.
A few nozzles still not printing?
Replace the ink cartridges:
As a final resort, replace the ink cartridge. There is a good chance that you will
have to call Epson for warranty repair, if the printer is still under warranty. For this reason we suggest that
this time you purchase original Epson cartridges. Never return an Epson printer
for warranty with compatible or refilled cartridges. Doing so will give Epson
the perfect opportunity to blame the problem on the cartridge or ink. While our experience with Epson printers
indicates that it is their built-in printhead technology which is to blame for most of their problems, you certainly
won't get anyone at Epson to admit it.
We have only one final suggestion. When it comes to purchasing your next printer, take a long, hard look at HP
or LexMark. If you run into clogged printhead nozzles with these printers, you can simply replace the ink cartridge
which has a new printhead built into the cartridge.

Epson suggests ... Note, they depend totally on cleaning cycles ... of course, they discourage refilling the cartridges!
