Roboter Kit IR Version is not working


Hello Team,
long time ago I bought this Robot Tank and build. But after pressing the IR it is blinking blue but nothing happened.
Please can you help me.

Maybe that I have to load a new program but I don’t know how.


Please describe your problem a bit more and troubleshoot, then I can answer you. Thanks!


this happens in rare but Make sure your printer is connected to the same wireless network as your mobile device. Open the Smart app on your pc , and then select your printer. Tap your printer, and then tap Print Quality Tools. make sure to Clean Printhead, tap Clean.
