Locating the Source of Problem

Locating the Source of the Problem

1Look at the front-panel display for any error message. For an explanation, see chapter 10.

2Test the plotter.

Switch the plotter off. Ensure that the power cord is firmly inserted in the plotter and plugged in to an outlet that you know works.

Switch the plotter on. Print a sample plot (see page 1-24). If the plotter plots this correctly, the problem is probably not with the plotter.

3Test your computer hardware and interface.

Ensure that you have the correct interface cable between the computer and the plotter and that it is firmly connected to the correct ports (see the sections starting on page 1-27).

Check that your plotter's graphics language setting (in Device setup / Lang) matches the requirements of your software.

Serial interface users only. Check that your plotter's serial interface settings (in I/O Setup / RS-232-C) match the requirements of your computer hardware and application software. See page 1-29 for details. Also, if you have changed your interface, switch the plotter off and then on again before trying to plot.
