Finding the Source of Your Problem
1 Look at the front-panel display for messages. See chapter 12, Front-Panel
Messages for an explanation of front-panel messages.
2 Test the printer.
n Switch the printer off at the power switch at the back of the printer. Make sure
that the power cord is firmly inserted in the printer and plugged in to an outlet
that you know works.
n Switch the printer on. Print an internal print. If the printer prints the internal print
correctly, the problem is probably not with the printer.
n Depending on the nature of the problem, you may want to print the image quality
print explained on page 11-8.
3 Test your computer hardware and interface.
n Make sure that you have the correct interface cable between the computer and
the printer and that it is firmly connected to the correct ports (see the Setup
Guide).
n Check that your printer’s graphics language setting (in Device setup / Lang)
matches the requirements of your software.
If you have changed your interface, switch the printer off and then on again before
trying to print.
