o
When using a USB hub, is it being used
correctly?
In the USB specification, daisy-chains of up to five USB
hubs are possible. However, we recommend that you
connect the printer to the first hub connected directly
to the computer. Depending on the hub you are
using, the operation of the printer may become
unstable. If this should occur, plug the USB cable
directly into your computer's USB port.
o
Is the USB hub recognized correctly?
Make sure the USB hub is recognized correctly on the
computer. If the computer correctly detects the USB
hub, disconnect all USB hubs from the computer and
connect the printer directly to the computer USB port.
Ask the USB hub manufacturer about USB hub
operation.
You cannot print under the network
environment.
o
Are the network settings correct?
Ask your network administrator for the network
settings.
o
Connect the printer directly to the computer
using a USB cable, and then try to print.
If you are able to print via USB, there is a problem with
network settings. Ask your system administrator, or
refer to the manual for your network system.
Printing from iPhone or iPad is not
possible.
o
Check printer settings.
❏ Connect the iPhone or iPad to the same network
(SSID) as the printer.
❏ In Web Config, enable AirPrint settings.

Printers, Printers, or Printers and Faxes folder; if
printing is paused, open the Printer menu and clear
the Pause check box.

Open the status dialog for your printer and check
whether printing is paused.
(1) Select System Preferences > Printers & Scanners
(or Print & Fax) > Open Print Queue from the Apple
menu.
(2) Double-click the icon for any printer that is
Paused.
