Problem Prevention

The following are things that you MUST NEVER do:

1)Never connect or disconnect the printer cable while either the computer or the laser system is powered ON. Always power down both units and leave them plugged into the wall outlet when connecting or disconnecting the printer cable.

2)Never connect the laser system through a manual switch type A/B switch box. If connecting an additional laser system or other printer to the same computer, we recommend the installation of an additional parallel port into the computer. Using a switchbox can create electrical noise that can cause an engraving problem or can damage the laser system and/or the computer’s electronics.

3)Never use any device that is installed between the computers parallel port and the parallel port of the laser system such as a ZIP drive or parallel port CD-ROM drive. This can not only damage the laser systems electronics but it usually will not work and will cause file transmission errors. Again, install an additional parallel port for other peripheral devices.

Computer Controlling the Laser System

At this time, you will need to read the second manual supplied with your system. It is called “Computerized Controls”. This manual contains Windows 95/98 printer driver installation and operation instructions as well as setup instructions for graphics software to properly work with the laser system. Please read this other manual before continuing on to Section 3.
