Even if the above trick doesn't work try this:


Similar to PrintX s solution in that you have to go into service mode first by ...
1.With printer OFF press and hold resume
2.while holding it down push and hold Power button
3.Release resume whilst still holding down power, the light should be green (not flashing)
4.Push resume once (orange) twice (Green)and a third time (orange)
5.release power button.
6.Then power it off and on again after it's finished making any noises and settled down.

This actualy clears the EEPROM so beware and only do this as a last resort.

This cleared the error for me.
