Error Code B859F646 (+ Power Sign)

[kkoun]

On the touch panel I see a blue screen with the "error code" B859F646 and a Power sign above it.

Any help is appreciated!!

@kkoun, Welcome to the HP Support Community!

Let us try these steps to resolve this issue:

Reset the printer

1. With the printer turned on, disconnect the power cord from the rear of the printer.
2. Wait at least 60 seconds.
3. Reconnect the power cord to the rear of the printer.
4. Turn ON the printer, if it does not automatically turn on.
5. Wait until the printer is idle and silent before you proceed.

Note: HP recommends connecting the printer directly to a wall outlet rather than a surge protector or a power strip.

Check for any paper jams inside the printer and if the print carriage is moving freely.

Refer to the steps mentioned in this document.

Let me know how this goes.
