TROUBLESHOOTING

 I

NFORMATION

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?

Problem

My word processor files do not print the way I have the menu and front 
panel set.

Solution

Remember: The note above!

Before sending a file to the printer, many word processors send either 
an “initialization string” or an 

I-Prime

 signal to 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.
