Auto Mode:
The switch automatically scans all input ports for print jobs. Flashing LEDs indicate that the switch is in the Auto mode.

completed, the switch releases the port and starts to scan all ports for another print job.
Manual Mode:
Each time the manual button on the end is pressed, the active port moves to the next port in the following order:: A Î B
Î D Î E Î Auto Î A. The illuminated LED indicates which port is active. When a port is selected manually, it is the
ONLY port that can print. The port cannot be changed during a print job or during the timeout period.
