Printing Does Not Start
Check 1: Make sure that the power plug is securely plugged in, then
turn the printer on.
While the POWER lamp is flashing, the printer is initializing. Wait until the POWER lamp stops flashing
and remains lit.
Note
When printing large data such as a photo or graphics, it may take longer to start printing. While
the POWER lamp is flashing, the computer is processing data and sending it to the printer. Wait
until printing starts.
Check 2: Make sure that the printer is connected to your computer
properly.
When the printer is connected to your computer with a USB cable, make sure that the USB cable is
securely plugged in to the printer and the computer, then check the followings:
If you are using a relay device such as a USB hub, disconnect it, connect the printer 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 printer over LAN, make sure that the printer is connected to the network with a LAN
cable or is set up correctly.
Check 3: Does an error occur?
Resolve the error according to the number of flashes of the Alarm lamp and the POWER lamp.

Check 4: If you are printing from the computer and there are any
unnecessary print jobs, delete them.

Check 5: Make sure that the inner cover (the cover of the disc tray) is
closed.
If the inner cover is opened, close the inner cover and press the RESUME/CANCEL button on the
printer.
Check 6: Is the manual feed tray in the paper feed position?
If the manual feed tray is in the paper jam clearing position, return the tray to the paper feed position
and press the RESUME/CANCEL button on the printer.
Check 7: Is the feed slot cover closed?
If the feed slot cover is opened, close it slowly and press the RESUME/CANCEL button.
Check 8: Does the page size setting match the size of the paper loaded
in the printer?
