Faulty / Working HP 4620 Wireless Printer see detatails (Harborne B32)

Hi all, as the advert says this is an HP 4620 Wireless Print/ Fax/ Scan/ Copy Printer which I have been using for about the last 5 ½ years but which I have now replaced due to its problems. See below:-
1/. As you can see in the one photo it no longer prints Magenta (well not much) even though the cartridge is full (I refilled it myself). I assume that the print head has got blocked but do not know for sure. All of the other colours seem to print ok.
2/. When I moved the printer from where it has sat for 5 ½ years a load of waste ink poured out of the bottom so I assume that the waste ink pad was full. It seems to have almost stopped now but you would need to check it out for yourself. It comes with a full set of new ink cartridges plus an additional black one. Polite replies only and please be aware of its problems!!. Kind regards Eric
