General Troubleshooting Guidelines

The troubleshooting guidelines provided in the following section are included to assist the
user. If the problem persists after you have followed the guidelines or if the problem does not
appear to be covered by these guidelines, call the Helpdesk.
Blank Display
When the terminal LCD screen does not show correct or clear readable information:
• Check the terminal batter level. Ensure it is not empty, if so please charge it.
Printer Does Not Print
If the printer does not work properly:
• The internal thermal printer receives power directly from the terminal. The green power-
on indicator light must be ON.
• Check to make sure the paper roll cover is properly latched.
• If the green power-on indicator is blinking or the light is red this is an indication there is
a problem. Open the paper roll cover and install a new roll of printer paper.
• If the problem persists, call your Helpdesk.
Printer Paper Jam
If paper jams inside the printer:
• Press the latch underneath the terminal to open the paper roll cover.
• Remove the damaged paper from the paper roll and clear the feed mechanism.
• Re-install the roll of printer paper, as described in Changing the Paper Roll.
• Check the paper loading instructions on the Installation guide.
• If the problem persists, contact the Helpdesk.
Keypad Does Not Respond
If the keypad does not respond properly:
• Check the LCD screen. If it displays the wrong character or nothing at all when you
press a key, reboot the terminal.
• If pressing a function key does not perform the expected action, refer to the usual
transactions section of this Manual to ensure that you are entering the data for that
application correctly.
• Has the keypad had any spillages recently, and are the keys sticking at all? If so please
try cleaning the keypad with a damp cloth as this could help.
• If the problem persists, call your Helpdesk
