Most probably these models comes with an external power supply. So all you need to do is to try changing the power chord first and if you have a volt-meter then do check if the supply is giving the prescribed voltage or not. If not then replace the power supply.
Yes I did all these step but it doesn’t direct any effect above the printer. Now its logic board is demage (means back side of main board i remove one part like 8 pin MOSFET from there) so I decided to replace by other formatted logic board buy from eBay. Thank you sir for giving me your precious information, Thank you so much.
Faulty power cords and connections are an uncommon but possible cause of a printer not turning on. Before suspecting a cord failure, ensure that there is power to the wall outlet and there are no conditions preventing the printer from turning on. Testing by substitution can confirm if a cord connection is the problem. Regards, Will
