HP laser jet 1020 formatter board issue- resolved

HP 1020 laser jet printer showed error of "unrecognised usb device" and would not be detected by any p.c.
So on youtube , theres a video to remove the formatter board of printer and place it in hot oven at 400 degrees for 5 min.

Done that with the board and now printer works like a charm.

The issue got resolved as the soldering wires used in board making get weather stuck and theres poor conductivity. Hot oven kind of resolders the board components.
