Printing Does Not Start
Check 1: Make sure that the power plug is securely plugged in, then
turn the machine on.
While the Power lamp is flashing green, the machine is initializing. Wait until the Power lamp stops
flashing and remains lit green.
Note
When printing large data such as a photo or graphics, it may take longer to start printing. While
the Power lamp is flashing green, the computer is processing data and sending it to the
machine. Wait until printing starts.
Check 2: Check the status of ink tanks. Replace the ink tank if ink has
run out.
Check 3: Open the Scanning Unit (Cover) and check to see if the ink
lamps are flashing red.
If there is still sufficient ink but its ink lamp is flashing red, an ink tank may not be installed in a right
position.

securely plugged in to the machine and the computer, then check the following:
If you are using a relay device such as a USB hub, disconnect it, connect the machine directly to
the computer, and try printing again. If printing starts normally, there is a problem with the relay
device. Consult the reseller of the relay device for details.
There could also be a problem with the USB cable. Replace the USB cable and try printing
again.
When you use the machine over LAN, make sure that the machine is connected to the network with
a LAN cable or is set up correctly. For details, refer to your setup manual.
