Well, if the tube is not disconnected at any point you should check if the  
pump is working.
Either see if there is a vacuum with your finger during a cleaning cycle  
or insert some colored water and see if it is sucked away.

If a great number of nozzles fails especially after you had a cartridge  
out, i would suspect the pump.
