Troubleshooting Solving Print-Quality Problems 750C Plus Solving Print-Quality Problems To achieve the best performance from your plotter, we recommend you only use genuine HP accessories and supplies, whose reliability and performance have been thoroughly tested to give trouble-free performance and best-quality plots. For details of HP media, see page 3-3 and the Supplies Source catalog supplied with the plotter. If the Color Is Not as Expected The means of accurately managing the colors printed by your plotter vary with the software application and driver being used. Refer to the following documentation: The Software Application Note for your application, in the specific package shipped with this plotter. Online documentation in the Microsoft Windows driver shipped with your plotter, particularly in the Color Options dialog box.

If There Are White Streaks in Solid Fill Areas This may mean that a cartridge nozzle is blocked. Unless you have switched cartridge check off (see page 3-26), the plotter normally detects this problem and tries to clear the nozzle automatically. However, some nozzles may still remain blocked, and in this case, the plotter will display Service cartridge(s) on the front panel. This means you should replace the problem cartridge, as explained from page 3-26. If you are unsure which cartridge has the problem, refer to the next page. 9-16
