The Trigger function is enabled in the default setting. This means that the laser is “OFF” until triggered by command or via the Auto-Trigger which is also enabled in the default setting. For some applications, you may wish the laser to operate continuously, although this is not recommended. This can be done by disabling the Trigger function using the S7 command. Once in the “Trigger Disabled” mode, the laser is on continuously.

The software trigger is actuated by downloading and <ESC> Z <CR> computer command from the host. (See Scanner Timeout to establish the length of time the scanning light remains ON after the trigger is activated.) A hardware trigger is not available with this scanner.
