I have the same problem but mine was caused by a power cut. This procedure is for a slightly different problem but might be worth a try.
1-switch off printer itself
2-switch off at socket for 20 seconds
3-hold down both black buttons on front
switch on at mains
4-switch on printer itself
green and red flash together
5-now switch off at mains and leave for 3 seconds
6-while holding down both front buttons again, switch on at mains
both green and red flash together so release
7-quickly hold down the left botton, the one with the scroll
icon above it.
Hold this until it resets itself, - the print head will re
charge and it will be obvious.
restting by unpluggin rather than turning off at mains tends not to work. hope this helps.
good luck
