HP Jetdirect 175x Print Server series - Manual (Page 84)

USB light blinking green
for HP Jetdirect 175x external print server/Internet connector for USB
and HP Jetdirect 310x external print server/Internet connector for USB
If the USB light is blinking green, it indicates that the print server has detected a good connection to a
valid USB device, but the print server does not support the device. For example, this would happen if you
connected a USB digital camera to the print server.
This is not a fault, but rather an incompatibility between the print server and the connected device. The
print server supports only USB printers (including USB multifunction printers and All-in-One devices). It
does not support non-printer USB devices, nor does it support USB cable extenders, USB-to-parallel
converters, or USB hubs.
Please check that your print server is connected to a USB printer. If your printer is not a USB printer, you
will need to substitute a USB printer or use a different model of HP Jetdirect print server (for instance,
one suitable for use with parallel printers).
Is the USB light now ON solid green?
If yes, click on the Yes button to return to the Troubleshooting Overview page and continue with the next
step of the troubleshooting procedure.
If no, but you are connected to a USB printer, your print server has a problem that requires assistance
from HP Jetdirect technical support; click on the No button for information on contacting HP.
