Hi, Rashed,

Thank you so much,

Isolate the printer, remove ink cartridge, printhead and paper

Try another power cable and power outlet


If the issue persist use the CQ890-67105 USB New Module with F/W SV


Good news, that's a lot cheaper than the Main PCA



Most times the issue is a bad firmware usb thumb drive mounted on the main board. They are available from hp parts for 25.00 which is the way I would first go since it is a lot cheaper then the main board which comes with the same drive.  The part number is CQ890-67105.


Just go to the link below and put the part number in to order.


You can find it here
