HP OfficeJet Pro 8620All-in-One Printer

I have 3 tvs not working as follows 40”Sony, 25” Toshiba and 21” Philips. I also have an HP Office jet pro 8620 colour print, scan, fax, copy, web printer. The printer is also not working, error message suggests out of ink but not the issue. I am about to take them all to the dump, just thought someone may like to try and fix them. There is no charge for any of these pieces. Pick up in Stoney Creek.
