How to Remap the platen.

  A. The platen is the part of the plotter in which the paper is loaded on.
     The Map Platen Test  adjusts for platen  irregularities to improve pen
     up/down performance.  This is accomplished by mapping the height of the
     platen with respect to the pen-up position at various points along its
     surface. It can also improve some media loading problems.  The Map
     Platen Test should only be performed if all other troubleshooting tips
     fail.  Accessing this test involves entering the plotter's
     diagnostic/test mode.  There are a number of tests available to the user
     in this mode that can be destructive to the plotter if performed
     incorrectly. To perform this test:

     1. Turn off the plotter's power.

     2. Place a Liquid Ball point pen (CalComp part number WLB) in the pen
        turret in pen position number 1.

     3. Do not load paper.

     4. Power on the plotter, when the logo appears on the plotter's LCD
        display, enter the CalComp Maintenance Code by keying in 8378 on the
        plotter's keypad.

     5. When the plotter displays: ONLINE, press the NEXT key on the
        plotter's  keypad twice.

     6. The plotter will display: (Re)Map Platen.

     7. Choose YES to (Re)Map Platen.

     8. The plotter will select the liquid ball pen from the turret and move
        it across the surface of the platen.  Remapping is then complete.
