Kodak ESPC310 printer ,poor quality prints

[NannyJan]

Any views on value of trying to clean mal functioning print head myself , have read up a bit online,against going for broke and buying a new print head . Any ideas on buying new print head on line rather than from Kodak direct ? Keen to save money , but not to be caught out by cowboy supplier of dodgy print heads .Many thanks advice much appreciated .
