Re: Hacking the Xaar 128 printhead
It should be 1MHz (or slightly less, if you use a timer on the CPU and don;t have a matching divider)

Re: Hacking the Xaar 128 printhead
The Epson printhead has a completely different interface than the Xaar head. I did not find specifications, but in general, the Xaar head has three supply voltages and a simple SPI interface. The Epson head, AFAIK, requires a quite complex power supply that uses a voltage pattern. The digital contro...

Re: Hacking the Xaar 128 printhead
Well, it seems like you are half way there. Getting any ink out is already a great achievement! If all nozzle fire, either your data transfer is messed up, or your ink head is broken. The pin that shifts data into the head, that decides which nozzles will fire, is MOSI. Ideally, look at MOSI and SPI...

Re: spectra nova 256 print head
Yes, the Xaar 128 requires compatible ink. Good luck with the Nova head. I am looking forward to hearing about your progress. Fingers crossed!beytullah wrote:The Xaar 128 print head is quickly failing

Re: Hacking the Xaar 128 printhead
Thanks, Simonsigns. It took me month originally to find the documentation on the Xaar 128. Eventually I stumbled over the original docs during a visit to China. By now, with some Google skills, the Xaar XJ128 Guide to Operation is quite easy to find. I know the board that you are talking about. Yes,...

Re: Hacking the Xaar 128 printhead
The purging procedure helps if the ink is clogged. If you have air trapped anywhere, the head can not build up enough pressure to eject the air. The manual explains how to fill the head the first time, and how to get the air out IIRC. The Xaar 128 is pretty tough compared to the Epson heads that, fr...

Re: Hacking the Xaar 128 printhead
Make sure that you use a compatible ink and that there is no air bubble in the head. This sounds very much like you have a bubble. You can suck it out of the head using a head cleaner with a vacuum pump. When filling the cartridge, make sure that the hose faces down, then put the ink in with slight ...
