This article provides troubleshooting tips for the Epson TM-T20ii thermal receipt printer, addressing issues such as the printer not printing receipts, being offline, or not connecting to the cash drawer.
If you're having issues with your Epson TM-T20ii thermal receipt printer, check out the following FAQs for troubleshooting tips and tricks.
Always start
by:
Restarting the printer (sometimes called power cycling)
Securing cables
Verifying paper is installed properly and feeds
Re-seating cables (re-seating simply means to unplug or remove and then to plug back in)
Follow the steps below:
1. Try restarting the printer by locating the power switch, turn it
off & on.
2. Check whether the AC adapter is correctly connected. It is VERY common
for the power cord to become disconnected from the power brick. Make sure
the cord is not only fully plugged into the outlet, but that it is also
tightly connected to the brick in the middle of the cord.
3. Verify the paper is installed properly by holding down the feed
button for several seconds
If the Error LED is on:
Check whether the roll paper cover is correctly closed
If the Paper LED is on, check whether the roll paper is correctly installed
If the Error LED is flashing:
Check whether paper is jammed. If it is jammed, remove it (Printing stops if the thermal head overheats and resumes automatically when it cools).
For other cases, turn the printer off, and after 10 seconds, turn it back on.
4. Check and make sure the paper was installed correctly.
This printer requires thermal paper in order to print.
This printer
does not require ink.
5. Verify the Ethernet cable is connected to the printer by opening the
printer and verifying that the Ethernet cable is connected to the printer
AND that there is a status light next to it indicating power. This cable needs
to be tightly connected.
You can also try restarting the router. For more information, see the
article Verifying your Internet
Connection.
If one of the lights shows as orange, it may be a cabling issue. Try using a different ethernet cable and make sure it's securely plugged into your router.
If both lights are green, and you're attempting to establish a connection
between the printer and a terminal station that's hardwired to your network,
make sure that the terminal has disabled the Wi-FI option.
