I did firmware upgrade on HP MFP 4345 and installed the newest release.
After reboot scanner/copy icons are not accessible with error 30.31.34 - scanner error.
I did not have any problems during install new software everything went pretty well.
Looks like installed firmware is to new to hardware what I have.
Any way to fix that ?
Did you see this before ?
I checked already some comments and people got this error because of loose cables in formatter etc.
Everything was working before upgrade so is not hardware issues. I already tried run machine without network cable connected because sometimes interfering with scanner. No progress. Still don't have access to scanning/copying options.
