Hi, is there some site/paper where I can fine the datas in order to recycle electronics? I mean, to save money I found the epson sx125 piezoelectric printhead (https://www.epson.it/products/printers/inkjet-printers/consumer/epson-stylus-sx125 here's the printer) in the "electronic trash shop" but have no knowledge about rewiring it. Can someone help to know what are the purposes of every components of its pcb?

 

I need to print with a particular resin that has almost the same viscosity of epson's ink. So I need to control every piezo in order to print with the precision I need. Nothing commercial, it is only a garage project.

 

Do you know the link? Or at least the forum? Anyway, thank you so much.

 

Oh no, I meant "have you tried and found useful the information in the links or the forum?". Anyway, I googled and found something very useful, thank you so much.

The epson print head is the most popular for research and reuse (hacking). There are many technical papers published through the FlexTech Alliance (flexible printed circuits, flexible displays and RFID tags). I think all of the pins are defined.

 

How do I access some of these papers?

Sorry, you have to attend conferences within the last year to get access. Also, the two papers I just checked used standard printers and graphics software - they just refilled ink cartridges with different media. Must be similar viscosity to commercial ink used by Epson. Finally, it appears the lower quality Brother printers have bigger ink drops for doing thicker layers. The epson is more precise. Epson can be hacked to give double drops but the software that calculates trajectory to impact has to be rewritten based on your distance-to-media if you redesign the print bed and double-shot print head.

 

My real issue is to rewire it. The software is not a problem I just need to know what each pin does and how much current and frequency need.

You'll have to root around the interwebs for more detail but it seems the information is out there.

Here is one site. I don't expect it will all be on a silver platter for your end application idea so It will take some work to get proficient. Here is one description...

There's plenty of info about hacking industrial piezo printheads but their cost is huge to me. Nothing precise about epson's one. Thank you so much, I'll keep googling around.

If you use the sea have term "pinout" you can get better results. Example
Pinout epson inkjet

Pinout epson piezo

Pinout epson printhead

 

Oh yeah! I found something interesting. Being italian is a problem because of the exact syntax of the google search ahaha. Thank you guys.

I could imagine! I checked and I didn't get any good results when I googled: "pinna-outa" Epsone

 

Ok, no way too proprietary. But I think I asked myself the wrong question. Why do more work than necessary? I think I'm going to buy a cheap entire printer, mount the x axis on a y axis and build an arduino thing to "decode" the gcode that sends 2D images of every layer to the printer and pauses it while increase the layer with z axis (that moves the bed). It's a dirty project but it should work without too much reverse engineering. My only problem is the waste of materiale in case of printer firmware automatic cleaning up of the nozzles and a way to translate the y circular axis in a linear y axis without delay due to communications issue.
