Erro code bb2643f4 / b85fdb70 Blue Screen - HP 477dw

HP Recommended
Mac OS X 10.11 El Capitan

Hi there,


we have a HP 477dw which always seems to have network connection issues. After we gave it a solid IP all worked fine for a while. Now today we got issues with scans en emailing and we got this bue screen with error code "bb2643f4".

After a reset it worked and later we received this code "b85fdb70".


Would be nice if they added an error code index. Does anyone know what this code means or have a link to a error code index or so?

Hope you are well,  for that event code its recommended the following troubleshooting:


- Unplug every cable connected to the printer, just leave the power cord connected. 

- make sure its connected to a wall outlet.

- turn the printer off and clear up the print queue of the computers connected to it. 

- clean up the spooler if windows computers are connected.

- turn the printer on and check if the error comes up after turning it on. 

- please keep the cables unplugged and try to print and internal report like config page and make a copy, make sure the error is not coming back.  Update or reflash the printer firmware.

- perform factory reset in case the error comes back up if possible and try the same testing again.

- if printer still getting error code even after the reset and with no connection at all , this may lead to a main PCA - circuit board issue and it would require onsite inspection. You may contact one of our authorized service centers for service.
