Epsom 890 printer problem

[sing2golf]

I have had an Epson Photo 890 printer for 3 years and very few problems.
However I am now getting black horizontal lines accross my prints.
Not all the time and sometimes just one short line. Other times it
can be several lines of varying length. either way it ruins the print.
This has been occuring for several weeks now. I have tried cleaning
the heads but it doesn't seem to make much difference. Can anyone
please suggest a cure or is the printer on its last legs. if so can
anyone say what the current equivalent printer would be please?
Thanks.
