Chapter 6: Troubleshooting
General Information
Here are some general things to check before proceeding with
detailed troubleshooting.
• Is the printer plugged in and turned on?
• Are the connections (power and interface) secure?
• Is the product being operated under the proper ambient
conditions?
• Does the paper being used meet the specifications for this
product?
• Is the paper properly installed?
• Is the ribbon properly installed?
• Is an Oki ribbon being used?
• Is the printhead gap correctly set?
• Are the correct printer drivers being used for the printer?
Note: Settings in your software application will normally
override any settings in your printer driver.
Printer driver settings normally override settings from
the printer menu or printer front panel.
