Hello everyone, I need help identifying a tool that I've seen being used in a few videos, I want to buy it but can't find it online.

It appears to be some type of EEPROM flashing circuit.

On the second picture I read HP7740HP7720 engraved to the mount, I'd think it might be a official HP tool?

Seems a bit of an excessive mounting solution for it to be an aftermarket tool, but for a official service provider or factory it would make sense.

I agree. Those things produce nearly no heat. I'm puzzled as to why such a complex/large mount.

Owner's business website is here:

Why not just email him and inquire. I'm sure he can use Google translate or another translate program if he doesn't know any English.

Hey wazz up! I am Mike from México, I just check some messages I see you talk about the device, I am the owner of pctek, we have these devices for sale to reset the logic cards, and so we can work the printers but without chips, it is an excellent alternative to save for the excessive expense of original cartridges quite a lot.
