Hello guys

I bought a new printer ( HP DeskJet 3630 AIO) which has a nice web interface and so on but I did something wrong by setting a password that I don't know. I can't access the features I normally should so I need to hard reset the device memory.

I opened it and found the kind of a mainboard but there are 2 rom chips, one of which should contain the printer settings but I dont know which one and how to properly reset it. I tried to search for any button combinations or tricks to easily reset the printer but found nothing, even HP support told me that there is no way to reset it but could it be done by somehow in the circuit? I noticed the serial connector pins near rom, which could be a possible way to do it.

I took photos of the main circuit.

Very strange.......I googled HP3630 password and it came back with many results, some even marked"solved". BTW......most say it's not a printer password but rather the wireless comms section.
