HP error code 79

Before you try the solution

1. 1. Copy the complete message exactly as shown, including any letters, spaces, or punctuation around 79.
2. 2. Find the printer's exact model number. The same-looking code can mean something different on another model family.
3. 3. Let the current print, scan, or update operation stop before touching controls, paper paths, or covers.

Manufacturer-documented solution

If the error is still there

1. 1Return to the screen or job that produced the message and check whether the code has cleared.
2. 2If 79 returns, do not repeat a risky procedure. Record when it appears and check the documentation for the exact model.
3. 3If the documented action does not clear 79, contact HP support or a qualified printer technician with the model number and complete message.

Other HP error codes

• 0x610000f6Carriage Jam — the print carriage has stalled or is physically obstructed, most often by a paper jam or a cartridge that isn't seated correctly. Not a firmware/communication fault.
• 13.xxPaper jam; sub-code identifies location in the paper path
• 33.05.0XSureStart error range covering boot-code corruption (33.05.00-03, auto-recovered, no action needed) and firmware that failed cryptographic BIOS validation (33.05.04-07, requires downloading firmware via the preboot menu) plus invalid boot/downgrade attempts (33.05.08-09).
• 33.05.1XWhitelisting error: a firmware file's digital signature failed validation, indicating tampering or a certificate problem. HP's fix: perform a Partial Clean, then if the device doesn't reboot to Ready, download firmware via the preboot menu.
