Print Cartridges
The DesignJet 250C uses the same four print cartridges as does the DesignJet 650C. The
DesignJet 350C uses the same three color print cartridges as does the DesignJet 750C and
755CM plotters andthe same black cartridge as the DesignJet 650C. The DesignJet 230 and
330 plotters use only the black cartridge which is used in the DesignJet 650C.
Distance between Carriage and Media
The distance between the carriage and the writing surface can determine image sharpness. As the
distance increases, the drop shape and directionality degrade and are more difficult to predict. You
can change the distance using the adjusting screw on the carriage. (Details ' chapter 7.)
