The test print use to look good exept for the black had extra lines and a few were missing. And its always had banding in the prints
 
the other day my coworker changed the ink pump be cause he said the colors where way off " blue came out purple"
 
Now the blue and black are messed up
and cleaning does not help any .
there is cross contamination between blue and black and half the nozzles are missing.
 
What should I do?
