Is there a specific error code that accompanies the 'E' error on the HP 319 that could help diagnose the problem?

Sometimes, the 'E' error is accompanied by a more specific sub-code displayed on the printer's control panel or within the HP Smart app. Note down this sub-code (e.g., E01, E02) as it can provide more precise information about the issue. Refer to the HP support website and search for the specific 'E' error code for targeted troubleshooting steps.
