Thank you
At last some progress well kind of .......
All back printing but its looking like this !! Anyone had this before or any ideas ??
Printhead was zapped. The signal received from the main board is getting corrupted. Most likely the power supply wasn't completely discharged before service session began. I've 3-4 of those heads in a box from another service tech's "adventures".. You could perhaps try to reinstall the printhead and ensure cables are seated properly, but I haven't had luck doing that.
When unplugging the printer, instead of waiting a few minutes for the power to discharge (which is suggested in a few Epson tech serv guides) - it's best to unplug the printer and actually press the power button to fully discharge the power supply capacitors. The machine will start to power up and then turn off when all is discharged. Depress the power button when it's complete.
You can even have a machine unplugged overnight.... and when pressing the power button next day, the green light can still come on and you can hear the electrical sounds from the back of the machine until the power gets fully discharged.
Sometimes when unplugging and pressing the power button, I don't see the light power up or hear the machine sounds of the discharge - which makes me nervous if I haven't any extra parts or at a remote location. - I'll always remove the back cover and disconnect the cable from power supply to main board. It's a good practice anyway when working on anything electrical in the machine - albeit, a real PITA removing all those screws.
