Hi just thought i’d share this as it fixed my printer (RX510) after getting problems

I found this info about reseting the RX510.

*Turn the printer off.

*Press and HOLD all the following buttons: Power, Load/Eject, Stop, B&W, Color.

*RELEASE BUTTONS when you see “Init eeprom” on printer screen. Press Colour
button to clear protection counter.

This will clear the message about parts in your printer reaching the end of their useful service life (you should also wash out the ink pads in your printer when you do this)

Hope this helps.
