Re: HACKING an inkjet printer printhead

Single head cards are relatively low cost (about USD$500), and perform most or all the functions of a wide format printer. These single head cards, sometimes called 1H cards, are commonly used for printing garment labels. I have only found single head cards for the Epson DX5, DX6, DX7 and other Epso...

Re: HACKING an inkjet printer printhead

Here is an assembly that might allow a XP PC or possibly a Windows 10 PC to drive 2 Seiko 510 heads, and also maybe just one head. The Seiko 510 should be suitable for 3D uv curing. This assembly has not been tested by me. Note that these boards are available for sale from a wide variety of vendors....

Re: Hacking the Xaar 128 printhead

Here is an image of the BOM for the Xaar Arduino assembly.

I am very concerned about the quality of the power supply. I am also concerned that this Arduino is too slow.

Re: Hacking the Xaar 128 printhead

About wetting of inks, consider page 33 of The Chemistry of Inkjet Inks, edited by Dr. Magdassi Shlomo. BTW, Dr. Shlomo does excellent research regarding inkjet and conductive inks. I have read a number of his scientific papers, and he and his students are top notch. Snippets of this valuable book c...

Re: Hacking the Xaar 128 printhead

I know the board that you are talking about. Yes, it is a great shortcut, but at the same time, it is again a piece of proprietary technology that makes writing driver software harder. Lastly, I have seen the UV curing with LEDs happen, but I cant remember the ink that was used. I know that you nee...

Re: HACKING an inkjet printer printhead

Here is a 50+ page presentation describing the characteristics of most of the commercial inkjet printheads available. The presentation includes some data about uv ink suitability. On pages 44-46 etc. it has lists of comparative data describing Max cP Viscosity, DPI, Drop Volume, etc., all of which a...
