A Brief About HP Printer Errors 0.x, 50.x, 79 & 30

HP Printer Error 0.x:

This error typically indicates a problem with the printer’s internal hardware or a failure during the setup process. It often appears when the printer powers on or during the startup diagnostic, indicating that an internal part is not functioning properly.

HP Printer Error 50.x:

The HP printer is experiencing a problem with its fuser, which is the cause of the 50.x error code. Fuser faults prevent your printer from finishing the print job since it heats and bonds the toner onto the paper. Common fuser malfunctions, denoted by “x” in the error (e.g., 50.1, 50.2, etc.), include warm-up failures and temperature regulation mistakes.

HP Printer Error 79:

This error indicates a firmware or network communication issue that disrupts the printer’s normal functionality. It often appears with a 79 service error message, and it can cause the printer to freeze, reboot unexpectedly, or become completely unresponsive.

In a networked environment, this error frequently arises due to corrupt print jobs or incompatible software commands.

HP Printer Error 30:

HP printer error code 30 indicates a print head or scanner mechanism failure. This error is most commonly found with multi-functional or all-in-one HP printers. Depending on your printer model, this error can also show up as “Scanner Failure” or “Print Head Error.”
