I don't think we are. Mine is an A3 printer
and is a K8600.
Mine has separate ink cartridges and print heads. All in cartridges and print heads are new from HP.
As I understand it, there is a tube that supplies ink from the ink cartridge to the print head. The print head has a small reserve...
Much like the previous post, I'm having an issue with an HP Office Jet Pro K8600.
The printer sat for a while after I retired but now I find myself in a position at the local food pantry that requires me to print a lot of forms, flyers etc.
I purchased new HP ink cartridges and print heads...
