Epson Printer All light blinking

I have Espon XP202 printer while Head moving during startup (Means Hardware Issue), I took massive number of prints and after that all light flashing. While, I check the alignment of sensor which attach with the main board. I also lubricated the spring roller beneath the wasting pad... On the other hand, I also clean the transparent disc which is attach to the gears and sensor and also cleaned the flashing light sensor. But the issue is remain same .Could you please suggest me.

 

If all 4 lights are flashing
A fatal error has occurred. Turn the product off and then back on again. If the error continues, check for a paper jam.

Thanks for your kind response... I already checked there is no paper inside printer.

 

Since the table says this
A fatal error has occurred. It seems like it needs servicing that has to be done by Epson.
