The printer paper comes out, but nothing is printed.
If the paper is coming out of the terminal but nothing is printed this usually means the thermal paper is installed backwards and needs to be turned around. Open the paper door on the back of the terminal, remove paper roll, set the paper to have the paper pull from the top of the roll, then pull approximately 3” of paper out from the roll. Then place the roll into the terminal with the paper pulling from the top of the roll. Then close the lid and tear off the excess paper. Reprint the transaction and verify the transaction is printed on the receipt. 2.6 The power cord is plugged in, but the terminal will not turn on. There can be several causes; • The AC transformer is defective – try another AC transformer and see if this works. • The power cord is defective – try another power cord.
The display is very dark, how can I brighten the display?
The display brightness can be adjusted within the Settings mode. From the terminal IDLE screen select Settings > Enter Password > Display > Brightness level > move the slide to the right to brighten the display and move the slide to the left to darken the display.
The screen times out and goes dark too soon, how do I adjust the display timeout?
The display time out sleep mode can be adjusted to change the amount of time the display stays on after no activity. The display time out mode can be adjusted within the Settings mode. From the terminal IDLE screen select Settings > Enter Password > Display > Sleep > select one of the displayed options 15 seconds, 30 seconds, 1 minute, 2 minutes, 5 minutes, 10 minutes, 30 minutes or select Cancel to exit without any changes. The Sleep menu will display the current timeout setting.
The terminal is not able to connect to the internet.
If the terminal is not connecting to the internet, please review all the Wi-Fi settings in the terminal to match the Wi-Fi network. Another step is to turn off the power to the access point and the terminal for about 3 minutes and then turn back on the power. Wait approximately 2 minutes and then check the connection. Also, the SSID and the password are case sensitive so please be sure to check these. If all the settings are correct, verify that there is Wi-Fi coverage where the terminal is located. Try moving the terminal closer to the Wi-Fi access point to see if the terminal connects. If it connects when the terminal is relocated, then either another Wi-Fi access point needs to be added to the network or the existing access point needs to be relocated to support good Wi-Fi coverage for the terminal location.
The terminal has intermittent Wi-Fi connectivity.
If the terminal has intermittent Wi-Fi connectivity, verify the terminal has good Wi-Fi coverage. If the coverage is good in all places the terminal is used, then please check the Wi-Fi access point channel to see if it competes with other Wi-Fi access points nearby using the same channel. If there are other Wi-Fi access points nearby with the same channel, then changing to a channel not used by any of the nearby access points will help minimize dropped connections. If the coverage is not good, then try relocating the terminal or access point for better coverage.
Another step is to turn off the power to the access point and the terminal for about 3 minutes and then turn back on the power. Also, check to see if power to the Wi-Fi access point is not interrupted. If the access point is using a switched power source, please consider a power source that is always on. Some equipment such as microwave ovens and curling irons can impact Wi-Fi coverage.
