HP Laserjet Pro M404dW Oxc9c60005 error code SX LIB SMARTDE.  this leaves the printer where it will come on and display this code, nothing more.

the error solutions are about performing a reset but how in this state?  is there a way to enter service mode via the panel and power buttons?  since no service manuals are no longer available (because i believe the manufacturers want you to have to discard and get another.  won't let you fix it yourself due to GREED) what procedure will allow you to shortcut the startup?  there used to be ways with different button combinations.
