HP Officejet printer (faulty) (Howey LD1)

HP Officejet Pro 8100 printer - it was working fine until the yellow ink cartridge leaked but it is beyond me to be able sort the problem....
It comes complete with user booklet, installation disc, cables...and a supply of ink cartridges for anyone brave enough to take it on (otherwise it'll be off to the tip). I have always used compatible ink cartridges and have never had a problem before so I think the fault is with the printer itself
I understand the compatible ink cartridges are suitable for other HP Officejet printers...if no takers for the printer itself!
