I don't have repleacement, but, I removed el pannel take out the batteries and put in back again and it works, thx

No need to change the button panel.in that old button panel, the number button -7 is pressing down all the while.(it is being stucked in) that's why the printer shows the warming up error.if we clean that panel, it will work perfectly.that's all....
