My printer works fine, but after a day or two, I get a blue screen with the error code: B337341F. A power off/on fixes it for a couple days then it repeats. I'd done a factory reset, latest firmware and ran diagnosis tool, nothing resolves it.  I cannot find anything online with that error code, anyone else know what it is and how to resolve?

Hi @gillettorg,

 

Welcome to the HP Support Community

 

I understand you are getting an error message B337341F on your HP Printer. Not to worry I will help you to get a resolution to resolve the issue.

 

Let's perform a power drain: 

 

  • With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.
  • Remove USB cable, if present.
  • Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.
  • Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord (This is important) and then plug back the power cord to the printer.
  • Turn on the printer and wait till warm-up period finishes and the printer is idle

Update the printer firmware :

 

  • Click here to download and install the latest printer firmware from your product
  • Click here to know different methods of updating the printer firmware.

If the issue persists, then wneed to perform a semi-full reset to restore the printer back to its original settings.

 

The reset instructions are specific for your printer and performing those steps on a different printer may brick the device. 

 

I've sent you a private message with reset instructions, follow the reset instructions to perform a full reset and re-initialize the printer.
