Pens are leaking.

A.    Verify that CalComp pens are being used.
      
      1.    CalComp pens and media are designed to provide optimal pen life,
            plot quality, and plotter performance. CalComp cannot guarantee
            quality with other brands of pens and media.

B.    Examine the pen caps in the bottom of the turret.
      
      1.    The type of pen cap in the turret must match the pen type being
            used. The pen caps are color-coded:
            
            a.    If using the CalComp Liquid Ink pens, the black caps should
                  be installed in the turret.
            
            b.    For all other CalComp pens, the colored caps (blue or red)
                  should be installed in the turret.
      
      2.    If the pen caps are contaminated with dried ink, then clean them
            with a q-tip and isopropyl alcohol. If they are torn, then they
            need to be replaced. (CalComp part #18367-0017, red caps for
            standard pens 12/pkg;  CalComp part #11320-0018, black caps for
            Liquid ink pens, 12/pkg).

C.    If using CalComp Liquid Ink pens, ensure that the pen tip has been
      tightly pressed into the pen body, forming a good seal.
