My english isn't good enough to tell it the nice way:

This is a collection of Nonsense.
Its just what it is : nonsense.

(Addendum : Today i learned the matching expression:  a red herring !)

Told of dumps, or worse: those who draw the better ( say : Money ) out of it.

However, if you are different opinion about the following tales, then don't tell me, I prefer others to think by themselves anyway.

Refilling is not that easy as the refill industry tries to tell the customers, but all that fairy tales around make matters worse (and make my brain hurt) .
 

Dried Sponges (78 etc)

Refilling amount

Dried Nozzles

Using adhesives to cover Nozzles

Using air pressure

Burnout

The 6578 is difficult to refill   New !

Air bubbles in the sponge chamber (78/23/17/41)  Newer!

Nozzler cleaner fluid    More Newer !

DI  Water   Even more Newer !

Dried Sponges (for 78,41,23)
 

Sponges of an empty 78 carry about 2 ml ink left in the sponge - per colour, together 6 ml.
This remaing ink cant be printed.
The sponge of an 19 ml 78 only gives 2/3 to 3/4 of the ink to the nozzles.

This remaingin ink will not drie out - through the tiny holes of the nozzles or the refilling hole.

It is even possible to leave the refilling holes open for printing - there is no disadvantage, and the cart stay week for me without even having start problems. (my refilled carts print the very first page perfect even after 3 weeks vacation. I dont even bother of it - i am used they do !)

Sponges do never drie out.
 
 

Refilling amount

Considering the above, the refill amount for a 19 ml cart should be perhaps 5 ml/15 total, and a 38 ml should get 10ml/30 total.
All known pictures of sponges show, that a 19 ml sponge has got ink only in a part of the sponges - and that after moths of storing and printing..The other part seems to "accept" ink only very unwillingly. Refilling the full amount would result in "too much ink" - and a cart that wont work.

I have had all my carts refilled in the 5-7 ml per colour area - and had excellent results.
now, i might have had to refill one times more that other which filled up to burting - but my carts did work all the time perfect. Refilling is a matter of minutes - and a sure result, if you follow the down-under procedure.
 

Nozzles drie out (for 78,41,23,45,15)

I have stored a 45 and a 78 for two weeks - open on the desk. They printed instantly, and if not, it was enough to wet the nozzle plate ( doant soak it - just make it wet with a few drops of water and insert into printer)

Nozzles dont drie out.

Therefore : Covering nozzles with adhesives

I dont use adhesives - and professionals dont recommend this anyway.

I store my carts in a air-tight box ( refrigerator boxes), a towel with a few drops of water added.
But take care the towel doesnt touch the nozzles - the ink will bleed out into the towel.
 
 

Blowing into Carts (für 78,41,23)
 

Blowing into the carts is killing it. ( see down-under , see Cart design, see Vakuumbehandlung   sorry to be translated in future)

Ok, blowing a tiniest amout of ink - as in down-under - is allowed. It depends on the sponge has to deliver that amount in apropriate time - otherwise ink will enter the nozzle chmaber - and the cart is dead. (ecept for reviving it down-under)
 
 

"Burnout"

Did you ever print several pages with an empty cart ? I did.
Did you ever have a reliable refill method ? I have.

I revived that cart - without problems - and it worked as good as before . The next prints where of the same quality as before - i couldnt distinguish them.

Even the patent informations about inkjet tell about "countermeasures against burnout", because "running dry is a normal case even in a original cart when a small air bubble goes through"

I do a test print with every cart before refilling.
How can i have the success rates that way ?

Burnout is fairy tale .

Addendum 29.8.02
It is worse. I think bornout has been invented to cover (excuse)  bad refilling methods.

"Did you run the cart dry before refillng ? For Gods sake - it burned out!"

6578 (23/17/41) is difficult to refill

My opinion, considering the typical ink sellers refilling instructions, and considering what I found about that carts, the 78 can't be refilled at all (reliably).

Reliable means that the cart works from the very first moment until ink out, without daily fumbling around, without occasional bad prints, without bad first pages after a week of non-use.

Fumbling around means shaking, blowing, fumbling, circling, printing test shhets, waiting a day, using cleaner liquid, and praying - in that order and one after another if the previous didnt work.

Fumbling is doing something which might work, but must not - in other words - just luck.

BUT - if you use down-under you will see the 78 is easy to refill (and quicker as a 45, by the way) .

I claim I can prepare 3 carts in a row according to down-under - and all the carts will work instantly at the very first attempt inserting them into the printer.

Addendum : somebody told me he did 50 carts in a row without any failure..........

Injecting air bubbles in the sponge chamber kills the cart

Now - the sponge chamber has air bubbles. All time.

For instance beneath the sponge - where roughness of the plastic wall holds room free for air. Open a cart , and you will see.

The ink doesnt fill all the room - neither in the chamber nor inside the sponge - or have you ever seen the sponge shrinks when ink is drawn out ? The ink is replace by air - even inside the sponge.
Or does the sponge grow, when you let it soak liquid ?? Where does the ink vanish ? It replaces air, which has been in the sponge.
All that is just normal!

Now - given that  - how shall some air injected into the sponge chamber be a be a problem during refilling ?
The air is already there. It is necessary it is there - otherwise the ink had not been able to go out.
And now the air has to go first - or the ink will not be able to get into the chamber. That means : when the ink is just in the chamber, then the air is already gone!!

Where is problem ???

Do you believe, the ink is so foolish - or so shy - to arrange around an "air ball" which is situated  - just - before the sieve ?? And can inhibit the "air ball" to vanish ? And that in spite of the fact, that the sieve arrangement of red is totally different to that of yellow/blue ?

And the ink cant get to the sieve??

Fit of giggles !!

First, i never saw a parachute stay in the air, when the springer touched the ground. No, the parachute falls dow, and the air from it goes up - just as gravity demands !!

Second, just imagine the air would be really trapped. But the sponge still touches the sieve - and the ink can "ride down" the sponge to the sieve - in spite of the air around. Thats capillary force.

The air cant inhibit it. There is air in the sponge - as usual. Doesnt matter.
 

The  Foam test  has shown - you can fill foam into a cart.
( since translation is due - a friend has filled foam into the cart, got it to work with down-under, and it printed reliably until ink out) .

Air bubbles in the foam chamber ?

That isn't a death horse - its a dead herde.
 

Summary: i dont call for injecting air - thats not the point.

But, there is no need to be afraid of a little bit of air, and no cause to sue that to be the death of a cart.
 

Nozzle cleaner

Thats another racket somebody has invented : nozzle cleaner.

First, ink is water soluble. What do i need to solve ink ? Its water.
If it gets tough - warm it up - warm water is a better solvent.

Another aspect :.
If you use some chemical solvent all around, what happens ?
( I speak of hp Tricolor)
OK, i will help. The cart has a sponge. The sponge will be soaked all over with your solvent. It now accompanies the remaining 2ml of ink, which are always left in a sponge (even in an empty cart) .... and the ink gets thinned - and mixed with the solvent.

And how to get that out ?? No Way !!
The ink refilled later will again mix up with that filth ......
I hear that people tell about that super sensible ink , how can that ever work ?? muahiuahua.....
 

I never have used nozzle cleaner.

I never had a need of it - all went well without, with water, with patience.
Even carts months old, stored open, have been revived.
 

Nozzle cleaner is a good thing for the bank account of the sellers.
And especially those, which have no reliable refill instructions....otheres don't need those rackets.
Nobody else has advantage of it.
 
 

DI Water

I just read it again, and the anger knocked me down.

"Use only DI water for cleaning, or the cart is dead for sure ."

Holy Lord, how can people be so stupid - and dare show it to the others that public ?

OK, You "Specialists",  how many calcium is solved in the water - if it is no DI water  - per liter ? 10 milligramm ?

And how can that get free ?

Right, the water has to evaporate.

I must admit: 10 mg will kill a nozzle, and to get that there you have to evaporate 1 Liter water in the nozzle  !

Oh - Oh, dont tell you have understood. Then you have to calculate (for punishment) , how many calcium will get free if you evaporate the volume of a nozzle in the nozzle ? Let us assume a nozzle has volume of a milligram ( much too much, btw, a nozzle is smaller) - then there might be in fact 10 picogramms of calcium set free. Sadly, thats only the volume of a shot, not that of a  nozzle, and the shot will throw out that with ease - consider the shot is something like an explosion.....

And this shall disturb - clog - a nozzle ? muahuahuahua.....

The developers have written in the patents, that the tintanium-aluminum-resistor has to be designed to withstand that explosions.... and that little tups of calcium will withstand ? Muahuahuahua..

Additionally, we dont fill the carts and let the water evaporate - we only bathe the cart and remove the water......

I never used DI water for carts until now.
