Cleaning refillable inkjet cartridges

Submitted by kenosky on Thu, 02/24/2011 - 10:55

What is the proper method for removing a metal oxide solution from an inkjet cartridge in order to fill the same cartridge with a new solution?

Also, the SHArK manual states to add HNO3 to metal oxide solutions, yet, HNO3 is omitted from the online recipes section. Is HNO3 required? If so, what role does it play and are there any suitable substittions?

New Software

Submitted by maa10 on Wed, 07/21/2010 - 09:37

Hi all,

We are testing the new software sent out on 7/20/10 and we have run into quite a few errors.
The new software will create a pop up box with messages like:
"Error in Performing Command - Error Code 236"
"Error Code 22 - Write to Device Fail"
"Error Code 31 - Read from Device Fail"
and then it will shut down.
We think it is because the LEGO NXT brick shuts off during the scan. Has anyone else experienced this problem?

Thank you,

Titration of Ink Base

Submitted by craymond on Mon, 10/13/2008 - 12:12

Here is the titration curve for the ink base. It's surprisingly simple to me and it appears there is only one acid-base active component. I quick look at Epson's MSDS for inks shows that 5-10% is an organic component, 10-20% is glycerols and the balance is ink and water. IF anyone wants more data from this let me know and I'll see what I can do.

Good "Calibration Metal Set" to Start With?

Hi all,

Calibration Card

Submitted by Megan on Thu, 07/10/2008 - 11:59

Would it be possible for us to get a PDF copy of the calibration card? We're experimenting with using pipettes to deliver metal oxides to the FTO slides, and we would like to use it to make a template.

Thank you!

Supply list in kits

Submitted by mgeselbr on Tue, 06/17/2008 - 23:08

I would recommend adding in a Parts List or Supply List with the kits that itemizes what is included. I don't recall seeing that. I feel lucky in that I had seen most of the components before and so knew what I was getting and could figure out more or less what each piece was for. I'm not so sure it was that obvious to someone who was brand new to the project.

What was the experience of other folks?
