HP officer pro 8620 printer (BA11)

Great printer- a trusty companion for the last 10 years.
We’ve been using Stinky Ink replacement ink most of the time but iIt isn’t currently accepting the black ink. There’s a work deadline coming up and I don’t have time to hack this solution so I’ve got a new printer on order. It might just be a new HP branded black ink cartridge to kick start it back to life?
Comes with a whole set of ink and will be a gift for someone with patience, technical curiosity and time on their hands.
Will be boxed up ready for pick up.
Best drop by an evening this week.
