A.     Possible problems:
      
      1.    There are raises in the paper causing the print head to touch in
            certain areas.
      
      2.    The customer is using incorrect media. The plotter cannot use
            standard mylar media on an inkjet-type plotter because the media
            has no place for the ink to dry.
      
      3.    Insufficient vacuum. Make sure that the fan (5324), or fans
            (5336) are blowing underneath the platen.
      
      4.    The platen or print head are defective.
            
            a.    Output the stitch plot and examine the eight by eight grids
                  (nozzle checks) for each of the four print heads. To do
                  this, perform the following:
                  
                  i.    Load the media into the plotter.  A-size media is
                        sufficient. Lower both the pinch rollers.
                  
                  ii.   Press ON LINE.
                  
                  iii.  After the plotter has sized the media, the plotter
                        will display either: ONLINE 0:00 or MANUAL 0:00.
                        Press the MENU key until the plotter displays: MENU -
                        USE ARROW KEYS TO CHANGE
                  
                  iv.   Press the UP ARROW key until the plotter displays:
                        INTERNAL TEST: OFF
                  
                  v.    Press the right (+) key until the plotter displays:
                        INTERNAL TEST: STITCH PLOT
                  
                  vi.   Press the ON LINE key.  Wait for the plotter to
                        complete the test.
            
            b.    If the nozzle checks show blobs of ink, white spaces where
                  a nozzle should be firing, then either the print head/print
                  station needs cleaning, or the print head assembly needs to
                  be replaced.  A print head can wear out prematurely by
                  allowing the ink tank to run dry. This will cause the print
                  head to warp.  CalComp only warrants the print head
                  assembly for 30 days.
            
            c.    If the plot output consistently shows an area clear and an
                  area smudged (e.g., left, right, or center), check the
                  following:
                  
                  i.    Check the media. Raises in the media will cause this
                        symptom.
                  
                  ii.   It is possible that the platen may be warped causing
                        the print head to touch the media.  Try placing a
                        straight-edge on the platen to determine if the
                        platen is warped. If so, this is not user
                        serviceable.
