Printout problems
The Ready light is on but nothing prints
Cause What to do
Your computer may not be 
properly connected to the 
printer.
Perform the procedure described in 
“Connecting to the Computer” in the 
Setup Guide.
The interface cable may not be 
plugged in securely.
Check both ends of the interface cable 
between the printer and the computer. 
If you are using the parallel interface, be 
sure to secure the connector using the 
wire retaining clips.
You may not be using the 
correct interface cable.
If you are using the parallel interface, 
make sure that the cable is a 
double-shielded, twisted-pair interface 
cable no more than six feet in length.
Some error may have 
occurred. 
Check the LCD panel to see if an error 
message appears.
Your application software is 
not properly set up for your 
printer.
Make sure that the printer is selected in 
your application software.
Your computer system’s 
memory is too small to handle 
the volume of data in your 
document.
Try reducing the image resolution of 
your document in the application 
software, or install more memory in 
your computer if you can.
