Printers from 10 years ago were much less protected and you could endlessly put ink in a 1 liter bottle for the price of a cartridge:
concrete case : the Epson stylus 740 where I was able to endlessly put ink in it and unclog it easily because its nozzles are not too fine and without a protection chip !!!!
(soak for a long time in water and ink solvent such as propyl alcohol)
The recent Canon MP610 (replaced by the MP520) also support, but are more difficult to unclog, because too fine !!

I'm fed up and I will restart the 740 !!!

The cartridges cannot be under real pressure because the ink would come out constantly, and therefore there is rather a system of circuit low pressure and capillarity studied to be blocked as soon as outside air arrives there to polymerize a product inside !!!!
Then the cartridge is in low depression but sufficient to block the ink outlet, as soon as the outside air arrives at the outlet before recharging !!!!
Almost all the laws of physics have been studied to block recharges !!!!!!
See the patents !!
And so you have to engage in a very very thorough scientific study to get around !!!
Manufacturers are constantly changing models, making it impossible to find the old one to two years (example MP610) to go faster than the development of ways to get around !!!!!!!!!!!!!! !

Anyway we find printers cheaper than their cartridges while in general they are the most expensive to use with non-separated cartridges containing nothing at all !!!!

Since the EPSON DX4450 is still selling at 40 €, it is good to say here concretely the supplier (s) of reset cartridges that work !!

Indeed it is a way to favor the current models which can be circumvented and which work !!!!
Instead of doing and repeating each in our corner sometimes ineffective experiences !!!!

Do not prevent these practices, in their "policy", on printer cartridges strongly resemble the method of planned obsolescence ...

Again: what are consumer advocacy groups doing?

I think that, as is soon the case for rechargeable phones on usb, a law or a world standard imposing a standard for cartridges ... Or at least that the same manufacturer uses the same cartridge for all his models !!

Yep! while we are at it, Europe should seriously legislate on car parts with a unique identifier on a multiplexed bus. Some of these parts (very expensive, such as the central management of electrical accessories) can only be used on one vehicle. Even a computer reset in an agency is not possible. A real shame. (if you can't fix it, you don't own it)

They do not seem to have put a tamper-proof unique identifier chip card on printer cartridges, but their price decreasing, it will not be long !!

We will have to wait for the cheap quantum computer to get around !!

Me, in 2011, I make my own eco-friendly printed circuits! It's my good resolution.

Personally, I haven't printed anything for over 5 years. When I really need to print (maybe once a year), I go to the copy center with my USB stick. It never cost me more than a cartridge, far from it (in general, I go there once with a lot of printing to do, it favors the discount) and I even got to a free binding! :D

I plan to use my printer for something else.
I hack everything that comes into my hand since I was a kid and the fever is not about to relapse : Cheesy: , so I immediately wanted to try to reproduce this with my printer that encumbered me (in English): https://www.econologie.com/fichiers/partager2/1293799534tP0IJf.pdf
Silver nitrate being exorbitantly priced, I prefer to experiment with copper sulphate and ascorbic acid (I will also try cheaper and just as eco-friendly oxalic acid, we find it in sorrel for example).
The experiment is underway and I have some ideas to improve the process including a pure copper plating afterwards ...
I will give more details on the protocol, the material and the results if that tells you.
In theory, the price of a simple printer (> 600 dpi and piezo preferably), copper sulphate, ascorbic acid, fiberglass and epoxy resin compared to an engraver, an insolator, the copper plates and the necessary products are beyond measure, especially if the ecological cost is taken into account. If in addition, you can get a printer from OCCAZ or free, it becomes really very interesting.

Ecologically, hydrated ascorbic acid (C6H8O6) or not (C6H6O6) is completely harmless and biodegradable. Copper sulphate is harmless if diluted in small doses but during the reaction, the residue is very dilute sulfuric acid. There is no obligation to throw it as is in the pipes!
Boil (> 100 ° C but <300 ° C because H2SO4 evaporates into SO3 from 340 ° C!) To evaporate the excess water in a non-metallic container and you have enough to replace the electrolyte of your car battery (2% H4SO30).
Otherwise, neutralizing the acid using slaked lime (CaOH) will give water and gypsum (plaster: CaSO4). This solution can even serve as a limestone amendment to your vegetable garden if its soil is a little too acidic. Not beautiful that ...
On the other hand, do not try this with the used electrolyte of your batteries because it contains lead sulphate and that it is not good neither for you nor for your plants.
All that remains is fiberglass and especially epoxy resin. I will consider alternatives later if the experience proves conclusive.
Otherwise, there is also a proven way to mask copper plates with toner, but you need a printer that accepts thick and rigid media, not to mention that it does not change much to the expensive and polluting basic process.
In addition, I have always found it stupid to sacrifice 40 to 60% of copper rather than adding as much without loss on the support. : Shock:
I also read somewhere (I think on ekopedia) that an academic had printed photovoltaic cells using an inkjet printer. The difference in cost must be even more obvious ... Unfortunately, the recipe is still kept secret. When will we have a technological wikileaks that we have a little fun? :P

This is the technique of "high flying", must recognize that it is great! Do you have links from other sites? Hack etc ...
What else is less "experimental" and which works quickly enough? Do you know Kipkay?

How to evaluate the coverage announced VS the actual consumption?

What alternative (s)? (Econologically speaking and how to calculate it).

At any time, since the printer costs a refill (40 €) !!
It all depends on what we print !!
but it is better to recharge with a liter of ink at the price of a refill of 10 20mL!
But you must know the difficulties to overcome the protections and chips, and therefore know if the resetters for sale work, and cheap inks that do not clog, hence the other tangible and not general!
Otherwise ecologically, by not printing anything, apart from iDTGV tickets, we save a lot of trees on the planet and we avoid the dispersion of harmful inks in garbage!

Obamot wrote:So the idea of ​​a "decision support" spreadsheet is justified! Since this is a typical case hardly "cernable".

let me very puzzled on what to put in the "hardly" "understandable" on the spreadsheet, especially, ink, solvents, and dirty fingers, to unclog cartridges and printheads designed to close in a few days, as soon as the ink is not that of the manufacturer, and the ability to get out of these traps, such as the flow of an ink in a cartridge DIY!


For the calculation for inkjet printers, it is indeed difficult to calculate, since the manufacturers have rotted the ways of hacking. I had chosen the Inktank system, but I had to give up because of the drying of the piezo print head with => Epson Stylus Photo EX (with PostScript kit) and Epson Stylus Photo 1200 A3.

In addition, the photo paper guide rollers take up ink and smear the sheets, so I decided to remove part of the roller guides. And ... it was becoming random DIY. So I fell back on Laser, with which the estimates are more quantifiable ...

But I will try to save the heads with isopropyl alcohol. What dilution do you use that with?

Yes, yes. I have others, I have to tamper with my bookmarks. It's as much a mess on my computer as it is in my office : Cheesy:
I jump especially on the occasion of this thread to disseminate this beautiful idea of ​​hack useful in report (must admit that this is not always the case).
Admittedly, this project is experimental but developed and tested by university researchers, not one by one guy in his garage.
It gives credit even if I have the greatest respect for garage hackers ...
KipKay, I didn't know no (hop in the bookmark, thank you).
I must admit that I have no preference for a diy or other site. It strongly depends on the subject. For the most part, the best rub shoulders with the worst.
But I will do a search on my computer and I will compile you if you want.
A site that I love for scientific information (theses, ...):
http://hal.archives-ouvertes.fr/
In fact, it is very rare to find all the good info on a single source, it is very often a puzzle ...
Except for this project I found by chance while looking for info on reprap ...
I'll post the compilation to you ... next year. : Mrgreen:
