Print quality and troubleshooting
Many print quality problems can be solved by replacing a supply or maintenance item that has reached the end
of its intended life. Check the operator panel for a message about a printer consumable. See the User’s Guide
for information about other ways to identify consumables that need to be replaced.
Note: Use only components and supplies from the printer manufacturer. Using supplies from other
manufacturers can degrade print quaility, performance, and safety.
The Quality Menu operator panel options can be adjusted to help improve print quality. For more information
about these menu options, see the Menus and Messages Guide on the publications CD.
In addition, the Enhance Fine Lines and Gray Correction options can be enabled to improve print quality. These
settings are available on the driver and on the printer Embedded Web Server (EWS) interface. For more
information about these options, see the driver Help.
