Thanks for the advice but unfortunately it didn't work.
The orange light flashes 5 times then goes green then 5 orange again.
I have done as you suggested. The light does notflash orange now but when I try to print I get a message to say the print head is not installed. I have checked it several times and it seems to be ok. Is there anything else you can suggest other than the bin?
Think I will go for a new printer. I will accept answer so you get paid.
