Epson inkjet printer (Harefield UB9)

Folks,
This is my dad's old Printer/Scanner
It's working, but he's just received a new one for his birthday...

It's old, but it still works, and it does work on Windows 11.

2 small issues...

The heads need a good clean... one of the colours isn't coming through, (I think yellow?)

It's supposed to be a network printer, but neither the ethernet socket, nor the wi-fi seem to be working. This might be an issue with the firewall on my dad's router, (but I don't think so as the new printer isn't having that problem!)

IT DOES WORK JUST FINE VIA USB

Also, I seem to have lost the mains cable. It's 2 prong type... as pictured.

Collection from Harefield UB9

I won't keep this for long. If no quick responses I'll take it to the "reuse" section at the harefield dump.

PLEASE NOTE... I DON'T ARRANGE COLLECTION BY ANY KIND OF MESSAGE/TXT... ONLY BY PHONE. I'm happy to have initial discussions by email, by arranging collection by phone only!

Regards,
Matt
