The Instructions Resetting for RX510, RX630 and CX6500 models Manually

Please see the big button on your printer like power on (this is on the left side) the colors black and white then stop button (these are on the right side).

1. First, pray to the God before you take an action, hopefully your printer will be fixed
2. Turn off your printer
3. Push the b/w + color + stop (or maybe OK button) together and hold
4. Push power on button and hold (so you push 4 buttons together) don't release all the button until you see the light indicator is blinking and then a message display on the small monitor
5. Release you finger from the button
6. Push the color button (once)
7. Turn off the printer
8. Turn it on again

I hope these ways can help you. Good luck...
