   setting.

   Note:
            If you adjust this value to change the density of the print for a
   particular image, an increase in the number increases the intensity of the
   colour. As a datum point the setting should be reasonably close to the
   resistance setting shown on the printhead (example R=3926) Because of the
   high numbers it is advisable to alter the settings in increments of 25 or 50.

   N.B.
 Altering the factory settings can cause printing problems if a different type of image is
 used at a later time.
