Large Epson printer, photocopier, scanner. WF 7710DWF (Titness Park SL5)

We are giving away an Epson WF 77100WF 4 IN 1 Inkjet printer, scanner, photocopier. It prints up to A3 size which other printers dont.
Dimensions 567 mm wide, 486 mm deep, 340 mm high. Weighs 18.5kg.
Obviously prints A4 and other sizes too.
It is still printing but not great quality. We are unsure what the problem is could need replacement cartridges. Not needed as was used for my husbands business before he retired. Good if you are happy to problem solve, or could be great for parts. Collection from Sunningdale.
