Digital BW, The Print

I have recently purchased a 1280 from a third party.I was told that
it was used very little and that it sat for a long time.So I purchased 
the cleaning solutions from MIS.I have been running the solution in
new empty carts through the printer cleaning cycle. I still can't get the 
printer to print any part of the test pattern. This seems out of the
ordinary.Can the nozzles be plugged so bad as not to let any ink through
to print any part of the pattern or do I have another problem with the
printer The printer does look to not have been used much there is not
much ink built up in any of the foam pads. Thanks if anyone can advise.
