This action is possible because the printer retains the last known printer
configuration prior to the power or LAN outage and uses that configuration
when the printer is booted again. In this case, the printer was already in
Diagnostics Mode prior to the outage, so it will still be in Diagnostics Mode
when booted again.
Note: Be sure to follow the instructions for ending the printer diagnostics
session when you are finished using the Toshiba Diagnostics for that
printer.
Situation 3
The Ethernet POS printer prints a message on the cash receipt station
stating that the printer does not have a MAC address. You might receive
one of these messages:
Message 1:
Need a valid MAC address for Ethernet communications.
Message 2:
Card does not have a valid MAC address.
Printer will run in Diagnostic mode.
Fixed IP 1: 169.254.0.95
mask:
The Toshiba Diagnostics for POS Systems and Peripherals Version 6.2.1 or
later contains a utility that can correct this situation.
Before you begin:
v Write down the MAC address, which is located on the Ethernet card
attached to the underside of the printer. The printing on the Ethernet card
should appear in this way: MAC: 6CAE8B46xxxx.
v The Ethernet printer must have printer firmware level 15.03 or higher
installed. If the correct printer firmware level is not installed, it must be
updated.
Note: If Message 1 is received, firmware level 15.03 or higher is not yet
installed.
v To update the printer firmware when the printer is in this state, another
interface (USB, RS485, or RS-232) must be used in the printer. The
Toshiba Diagnostics package can be used to update the printer firmware.
Once the firmware is updated to level 15.03, put the Ethernet card back
in the printer and proceed with the rest of the instructions.
Follow these steps to put a MAC address into an Ethernet attached printer:
1. Connect the printer directly to your laptop or to the POS system unit
with an Ethernet cable. It may be necessary to have your own LAN
cable to connect the printer to the laptop.
2. Insert the TGCS Diagnostics Ver 6.2.1 or later memory key into one of
your system's USB ports. The printer should already have power from
a power brick when the Ethernet card is in the printer.
3. Boot the system to which the printer is attached.
4. When the printer powers on, a message is shown about not having a
MAC address. The printer is already in Diagnostics Mode at this point.
5. Navigate to the UTILITIES screen.
