Then do this...
v Check the power to the printer.
v If connected to a system using the RS-485 communication port, check that
the system is turned on and that cable 7 is connected.
v If using the RS-232 communication port, Ethernet communication, or a USB
port with a power brick, check that the brick power supply is connected to the
printer and plugged into an AC power source.
v If using USB communication with a powered USB cable, check that the
system is turned on.
v Check that the customer receipt station has paper loaded correctly. Close the
cover and push the Customer Receipt Feed button to feed a small amount of
paper.
v Check that the paper door is closed.
v Verify that the cutter does not have an error.
v If connected using Ethernet, verify that the main logic card supports Ethernet.
If Ethernet is not supported, a message is printed out (only applicable to
firmware 14.00; no message is printed for earlier versions). You must change
to another interface or replace the main logic card.
v Ensure that the paper roll is not upside down. Go to "Loading and replacing
the paper roll" on page 35.
v Clean the printhead. See "Cleaning the thermal printhead" on page 37.
v On an Ethernet printer, verify the firmware file is greater than 14.00.
v Paper out sensor Type 1 will only work with 9.x firmware or later.
v Perform an online test to determine which sensor type you have.
v Check printer firmware level by performing an offline test.
v If firmware is an earlier version than 9.x and the paper ready light stays green
when the paper is out, update the firmware to 9.x or later.
v Perform the paper out sensor test in the offline menu.
v Check that the Ethernet cable is plugged into the printer and the LEDs are lit.
v Check that the printer has an IP address by running an offline test.
v Check the network that the printer is connected to.
v Make sure the logo has been downloaded via the configurations utility or that
the application downloads the logo via UPOS.
v See "Ethernet Configuration" on page 6 for more information.
