Multi-function ink-jet printer (Truro)

Mostly working HP OfficeJet Pro 6978. Wireless, duplex, prints, scans, faxes. Color printer, but blue is clogged, and I couldn't fix. Prints b&w, scans, duplex perfectly. Pick up in Truro, MA. Like this: https://www.hp.com/us-en/shop/pdp/hp-officejet-pro-6978-all-in-one-printer
