Some suggestions for unclogging your Epson printers

How to tell what the heck is the Nozzle test really showing you

How to tell the difference between a air pocket and a true clog

You see if you get a lot of random skips when doing a nozzle test you more that likely

do not have a true clog you really have a few air bubbles in the print heads. Just doing

clean cycle after clean cycle is not the best way to purge out the bubbles. you are farbetter off just letting the printer sit overnight or printing random test and a few pages of

color blocks.

2000P nozzle pattern

Also if you still get random skips then it is time to reseat the cartridge all you do is lift

the blue cartridge locks and push then down. This will burp out those air pockets that

have been known to lock up a print head.. In the worst case you can remove the

cartridge and knock it on the table top yes ink will spill out but this is what you want to

seeink spilling out of those feed holes. Now once you do this the ink counter or ink

low lights will not work so you have to keep a close eye on the printer when you see theink stop flowing stop the printer!!! These print heads do not like to be run dry!! Now if

you always have the same nozzle that skips then you may have a real clog. The Windex

trick really does blow out just about the worst clogs. And Windex is cheap and it will

not hurt you or your printer.

The cleaning pads are those foam pads located under the print heads when they are in

the parked position (power off) The pads are colored with guess what .the ink you are

using!!! The are about 1/2 x 1 inch and they are under the carriage or print heads when

they are parked! But please be careful. As I have posted before, do not contact those

cleaning pads; they are spring mounted and they can be knocked out of position very

easy! Once you have knocked them out of position it is time to send in your printer toEpson!

After trying cleaning cycles, you can try my trick of carefully dripping only 5 or so

drops of Windex (from a new bottle) on the cleaning pads. Just drop about 5 to 6 drops

of Windex [A better solution is a mix of distilled water, household non-sudsy ammonia,

and cheap vodka. An ounce or so of the vodka and ammonia to a liter of water (It

doesnt seem too critical)] on the pads (unscrew the sprayer and drip the windex out of

the feed-tube) and then make sure you turn off the printer this forces the pads up to the

print heads and the Windex will do its thing very quickly! About 1 hour works most of

the time - overnight on the clogs from hell.

2/8

You can also drop windex on the ink inlets in the carriage, but try the pad trick first.

After you tried the pads trick 2 times: You can drop Windex directly on the spikes in the

bottom of the carriage. These will be seen when you take out the cartridge. You must

remove the cartridges to see the spikes. Here is what you do:

Make sure that you turn off the printer before you drip on the spikes!do not drop more than 7 drops from a clean eye dropper!

Wait at least 10 minutes and drop 5 more drops on the spike, You also should put 2

drops on the other good ink feed spikes to prevent them from drying out (it happened

to me!)

After this, install the cartridge making sure that when you install the cartridge the ink

out light goes out!

You may have to run up to 2 to 4 clean cycles, this is normal in your situation Just make

sure that you do not exit the clean menu and continue doing cleaning and nozzle checks

You must stay in the utility menu for the printer to use increased suction, you must alsorun a nozzle check between cleaning cycles, or the printer wont actually clean its self,

just spin the roller. Each time you repeat a cleaning cycle without exiting the menu, the

printer will use increased suction (contrary to popular belief, the print heads arent

actually spraying ink out during the cleaning cycle, rather ink is being sucked through

the heads by a pump).

3000 nozzle pattern

This works very well and should be tried before you go trying windex! This not only

will clean the heads but this will align the heads, it is a procedure I use for both cleaning

& head alignment. Compare the test prints as you go to see if you are making any

progress. Follow these closely:

while the printer is on hold down the button with the ink drop icons on it for 5 seconds.

This will do a clean cycle by the printer. Do this a couple times.

Now shut off the printer and while holding down the paper advance button, turn on the

printer (dont release the paper advance for at least 5 seconds) this will print a nozzle

check pattern.

If you have a clog or head out of line, repeat the first procedure AT LEAST 3-4 times.

Then repeat the second. If the heads are REALLY BAD you may have to keep going, as

long as you can see that the heads are being moved or the test pattern changes with

these cycles.

hoping this helps-

Canon waste ink reset

Sunday, June 24th, 2007

Thanks a lot for all postings. My question: would you buy a car,

which stops sunday midnight on the middle of the highway telling you:

service required - and all behind that is a code?

OK - I worked around the waste-ink message on my i550 with all this

postings, now it is working again BUT I must have pressed a button

once to much, since it will now not turn on or off from PC-input,

only manually. Does anyone have information about an overall-reset

resp. how to do this?

A hint for those using mostly BW-text: as I found still the colorwas draining, obviously the initial cleaning uses all colors -

a bit expensive after a while.

I took empty color tanks and filled them with water, added a tiny

sprinkle of glass-cleaner and alas- the head is kept in order as

I am printing 99% text. Disadvantage: when changing to colortanks

you would have to run a little while on color to clear the system.

Filling on the fly is easy, if you drill (or melt) a tiny hole on

the top of the tank and put a screw in to seal it. If you open the

cover, it will move to the middle and you can unscrew and fill with

a syringe - but do it quickly, as the inner suction balance of

the tank is disturbed : which means simply, it could start dropping

during the filling process.

Canon by the way does top this type of service: they asked me, if I was helped properly

by the helpline (means: sending the printer for repair) in a questionaire, in which you

undergo a psychological test about lying on the information, which you contribute for

their business: nice going.


I just got a note that parts are at the end of their service life what do I

do?

Sunday, June 24th, 2007

This is from a customer suggestion:

BREAKING NEWS-It is possible to reset the counter for an Epson R320 Printer via buttons.

The general procedure is as follows:

1. This will only be enabled when the warning message has been received indicating

that some parts have reached the end of their life and the printer will no longer print.

(The first warning will indicate that some parts are nearing the end of their service life,

continue using the printer until the second message is received.)

2. Press the STOP and MAINTANENCE buttons and hold until the printer LCD

displays a message telling you to turn off the power.

3. Turn off the power at the printer and wait several seconds.

4. Press the printer POWER button and turn the printer back on. If it doesnt respond,

then unplug the power from the 110 VAC line and wait a few seconds.5. Plug in to line power and press the printer POWER button. The printer should turn on

and the counter should be in the reset condition.

6. However, it may not print. Shutdown the computer and the printer and then turn them

back on (the printer may need to be reinitialized after the counter has been reset. In

some cases, it may be necessary to uninstall and reinstall the printer driver s/w.).

7. Press the maintenance button to position the cartridge in the change cartridge

location.

8. Clean the waste ink pad using your prescribed method.

9. Press the OK button to return the printer to normal operation.

It works!

Take care; Bob Jaquess
