Welcome to the HP Support Community.

Let's try to reset the Printer here:

Are you able to copy?

Reset the product

• With the printer turned on, disconnect the power cord from the rear of the printer.
• Unplug the power cord from the wall outlet.
• Wait at least 60 seconds.
• Plug the power cord back into the wall outlet.
• Reconnect the power cord to the printer.
• Turn the printer on. HP recommends plugging the printer directly into a wall outlet.

Also, try connecting the Printer to a different wall outlet directly.

Try ta firmware update: https://support.hp.com/in-en/document/c02919168

Dear Sir,

                  Thanks to reply. But the you send  me solution i read earlier in google but nothing happened.

                   My question is that why this problem occurs? And what is the correct solution of this. You send me

                   solution this is  hit and trail method.  I read many review's but all said nothing happened. First go to in root of                           the  this type of problem and technically   find why this occurs ? If the power light  is blinking there is no                                    possibility of any copy or any other work. Only Scanner is working.

                                                                                                                                                         Thanks and Regard's
