New Technology That Will Keep Your Inkjet Cartridge From Drying Out

One of the ongoing problems with the inkjet cartridge is that if it is not used enough the ink that is left inside each of the microscopic nozzles in the print head drys up. OK, lets back up a bit for a quick lesson on print heads. On all inkjet printers what actually drops the ink onto the paper is what is called a print head. There are print head cartridges which has the print head attached to the print cartridge and non-print head cartridges where the print head is not part of the cartridge but is housed inside the printer.

This is a sample of a print head cartridge:

(A) Is the electronics where the information from the PC is sent to the print cartridge and tells the print head (B) how much ink and what color ink in color cartridge to fire out of each nozzle. There can be any where from 600 to upwards of 1200 of these microscopic nozzles on a print head.

 

Here is a sample of a non-print head cartridge, there is no print head on these types of inkjet cartridges, they are basically a tank that holds the ink.

So, in either system the nozzles can become clogged with dried ink usually from not using that print head enough. Leaving an inkjet printer sit to long without using it is deadly, the ink will dry in these nozzles. Is there a way to prevent this? Well, an engineering team from the University of Missouri have devised a clog-preventing inkjet nozzle by taking inspiration from the human eye, no kidding. I love this kind of thinking. As a film of oil keeps a thin layer of tears from evaporating from the eye, the devised nozzle uses a droplet of silicone oil to cover the nozzle opening when not in use. Because the inkjet nozzles are so small and the area that these nozzles are found is in a very restrictive area trying to duplicate the motion of an eyelid moving across the nozzles was out of the questions. What they did was move the oil across the nozzles by an electric field.

Eye, Tear drop

Jae Wan Kwon, one of the members of the team put it this way, “The nozzle cover we invented was inspired by the human eye. The eye and an inkjet nozzle have a common problem: they must not be allowed to dry out, while simultaneously, they must open. We used biomimicry, the imitation of nature, to solve human problems.” Most inkjet printer’s will attempt to clear the clogged nozzles by forcing a burst of ink through the nozzles, this is costly and wasteful. Basically the expensive ink that you pay for is used as a cleaning solution! And this method of clearing the nozzles uses a lot ink, think about it, you pay top dollar for your ink cartridges and then they use it as a cleaning solution to clear dried inkjet nozzles, Jae thought, they must be a better way!

You may be wondering why the company’s that make these inkjet cartridges did not think of this or at least hire a team to look into it. the answer is simple, greed again. Epson is notorious for using massive amounts of ink to clear their print heads. It seems unless you are constantly using an Epson printer the print heads are prone to clogging. I’ve had many customers come in to buy a full set of cartridges in an attempt to clear clogged Epson print heads just to come back the next day and tell me that they went through all of the ink trying to clear the head’s! Of course now they have to buy more ink just so that they can print, win win for Epson. If the procedure did not work they now have to make a decision, buy more ink to try again or just say the hell with it, throw the printer away and buy another one. Not very ecologically sound to say the least.

If the technology that Jae is working on works I wonder what the chances are the major printer manufactures will embrace it? My bet is they won’t want anything to do with it, why would they. In the case of non-print head cartridges that uses a system like Epson they would look at it like they would lose money, why help to keep the nozzles open when if they clog they get to sell more ink. In the case of the print head cartridge, there really is no way to clear and open the nozzles, once they are clogged by dry ink, the only real choice is to throw them away and buy new ones, this is a money maker for the large printer manufactures that produce there own cartridges.

Only time will tell if this technology makes it to the general public, who knows maybe the big boys will get a change of heart, maybe they will actually care about the end consumer instead of just profits and do something that will really help them to save money. Oh yea and don’t forget that it would help the environment in that all of the ink would actually be used in these machines which would keep them from the landfill longer. Let’s see what happens.

We would love to hear your comments on this subject.

  1. Hi there! This article could not be written much better!
    Looking through this article reminds me of my previous roommate!
    He always kept talking about this. I most certainly will send this post to him.
    Fairly certain he’ll have a good read. Thank you for sharing!

  2. Sweet blog!! I found it while searching on Yahoo News.. Do you have any tips on how to get listed in Yahoo News??? I’ve been trying for a while but I never seem to get there!! Cheers Roofing Repair of Irving, 1117 Brandon Ct., Irving, TX, 75060, US, 972-200-4770

    • No I don’t know of any way, as far as I know it’s just a search engine so you can’t “get listed”
      The best advice I can give is to keep posting on your blog so when other people search you will show up.

      Thanks for the comment

  3. I currently own 3 Epson Stylus 1400′s, 1 Epson Artisan 1430, and two Epson Workforce 7010′s. I run dye ink out of two of them (a 1400 and the Artisan) and pigment through the others, all using CIS systems. I ended up buying an empty CIS for each model, and filled all the tanks with a mixture of 2/3 Windex (amonia based) and 1/3 70% Isopropyl Alcohol. Once per week I run about 100 prints at high resolution through each machine to let the solution go through the nozzles and print heads (as well as into the waste areas). I also run about 4-5 head cleanings. Once I pop the CIS cartridges with actual ink back in, they run pretty good.

    I’ve also started using a cleaning solution my supplier recently picked up. It has a light citrus smell and a light oily texture. It has to have some silicone or oil lubrication in it, maybe some orange oil? It is said to be specifically formulated to break up pigment ink build-up and to lubricate the nozzles….and I have to admit, after scores of hours of cleaning these nozzles, using direct injection of pure amonia, alcohol, etc, this stuff actually worked. I just wish I could figure out it’s composition.

    One thing I also tried with success on hard to remove clogs was to place an amonia-saturated square of paper towel under the ink carriage on it’s docking station over night. After a few weeks of doing this nightly, a printer that had set for a year had all of its nozzles clear up.
