T-45 series printer

My T-45 printer/fax/scanner/copier black ink cartridge continues to have excess ink on the outside of the cartridge all the time.  Therefore, it streaks and makes a mess of my printouts.  I'm using a HP cartridge.......the second one I've tried since the problem began.  I keep cleaning the cartridge, but to no avail.  Help!  

Is a HP cartridge the correct cartridge to use?  Maybe you need it serviced.. depending on the number of prints it does you'll need to service it occasionally.
