Re: HACKING an inkjet printer printhead

Hi Dragonator : Good question, I was not aware you could get a USB or PCI controller for that. PrintMon software and pci-cards and usb cards are available for Seiko, etc. Seiko, Xaar, Fujifilm, maybe Ricoh/Minolta are useful to the 3D enthusiast, as they can jet the uv curing resins suitable for 3D....

HACKING an inkjet printer printhead

Inkjet printheads can be divided into 2 groups : The first group, which is useful to 3D printing enthusiasts, are printheads which have wide latitude for ink viscosity. These heads allow inks from 5 cPs to 50 cPs at room temperature, and higher viscosities at elevated temperatures. This group is com...

Re: Hacking the Xaar 128 printhead

Has anyone attempted interfacing this device with RIP shareware such as Onyx Graphics? or in Asia, MainTop? or performance testing shareware such as PrintMon? (Note that PrintMon may only be available for Seiko heads, although I have read hints that it has been adapted to the Xaar as well). Any sugg...

Re: Hacking the Xaar 128 printhead

Very low viscosity uv curing ink ingredients are available from Allnex. They are very easy to formulate and have viscosities at room temperature under 10 cPs. Regarding solvents for inkjet printheads, IPA should be OK, but it must be filtered with a 0.4 micron filter before use. Some workers recomme...

Re: Hacking the Xaar 128 printhead

Hello, guys, I managed to reduce the CLK signal to 1MHz by increasing "OCR1A = 11; //7;" from 7 to 11. When I look at SCK, the frequency is much higher than 1.4 MHz. Is that admissible? TCCR1A = _BV (COM1A0); // toggle OC1A on compare match OCR1A = 11; //7; // top value for counter OCR1A = Pin11 //...
