• Select another Color Correction option in a supported driver and print your image again; refer to "Deciding which color correction to use" for more information.
• If you are not using a supported driver and are sharing the printer with other users on a network, another user may have changed the printer's color adjustment setting. Refer to "Sharing the printer on a network" for more information.
• If you use the driver's Use Printer Setting option and printed colors are not what you expected, check the following:
  • A selection may have been made with the switches on the printer's rear panel. These settings change the printer's color correction setting.
  • A color correction utility file may have been downloaded to the printer. These files change the printer's color correction setting.

  Refer to "Sharing the printer on a network" for details on how these settings affect prints made from a driver.

• If you have the printer's extended features option, you can use PhaserMatch to customize profiles for better color matching between the printer and a specific printing press. Refer to the PhaserMatch User Manual for instructions.

If you have questions about PANTONE Color Matching, refer to the HAL article on PANTONE Colors. Refer to "Using the automated fax systems" for instructions on using the HAL and EuroHAL fax systems.

There are many variables in process reproduction of colors generated by the Phaser 300X printer, any one of which may affect the quality of the PANTONE Color simulation, including:

• Type of ink used
• Type of ink film used
• Effective final resolution
• Dot structure/halftones
