No Power When The 300 System is Turned On

If the 300 does not initialize or the fan does not spin when the power is turned on there are a few simple steps to follow to determine if a serious problem has occurred.

1.

Check the power cord. Make sure that it is firmly plugged into the wall and into the back of the plotter.

2.

Check the voltage at the wall outlet and verify that it is within the operating limits as specified in Chapter 1, Specifications.

If there are no problems with the power to the 300 System proceed to the Mechanical,

Electrical, and Electronic Diagnostic Process later in this chapter.

The 300 Won’t Respond to the Computer

If there is a problem getting the 300 to accept commands from the computer, perform these procedures:

•

Verify that the communications cable is correctly connected to the plotter and to the proper communications port on the computer.

•

Check to see that the computer LPT, or COM port that is being used is configured to match the 300’s serial, or parallel port settings.

•

Make certain that the file and the 300 are set to the same plotter language.

•

If the connection is good and the port assignments appear to be correct, proceed to the next section.

Communication Problems

Many plotting problems can be resolved by testing and adjusting the communications between the plotter and the computer. There are three diagnostic tests that can be run from the 300 Control Center. These tests are designed to help determine if there are communications problems and isolate where the difficulty is occurring.

The last two tests require a diagnostic module (available from an Ioline dealer) connected to the serial port on the computer or the 300. If the following tests do not resolve the problem and the computer and software are working properly, proceed to the

Mechanical/ Electrical Diagnostic Process later in this chapter.
