USB light blinking amber
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 amber, there might be a hardware fault (for example, a short-circuit,
faulty cable, or a printer drawing too much power).
To verify, disconnect the USB cable at the print server. Switch on the printer if it is off. Power cycle the
print server (unplug it and plug it back in). Then reconnect the USB cable. If the USB
light is now
green and steady, then no problem remains.
Otherwise, if the USB
light is still blinking amber, then there may be a faulty component. Try these
steps to determine which component might be causing the problem:
● Detach the USB cable and power cycle the print server (unplug it and plug it back in). If the USB
light is green and steady, then the print server is OK. If it is blinking amber, then the print
server is faulty.
● Try reconnecting the USB cable to the print server only, and power cycle the print server (unplug
it and plug it back in). If the USB
light is green and steady, then the cable is also OK. If it is
blinking amber, then the cable may be faulty.
● Power cycle the printer and reconnect the USB cable to the printer. If the USB light is green
and steady, then the printer is also OK. If it is blinking amber, then the printer may be faulty.
