Error 30 and Scanner random movements

[kir44]

My printer just so happened that it started make random "scanning movements" like Its jammer or something;

I tried to reset it, bc I got Err30, but I didnt help; I tried then a complete reset and didnt do much, whenever i try to use the "Scan" from the Hp Smart app, I just tells me that the printer is busy. Some times after trying to scan, the scanner "jumps" and dont sit in what I would tell is the correct position (completely to the left).

Hi @kir44,

Welcome to the HP Support Community! 

Thanks for reaching out about your query regarding your printer!

We're thrilled to have the opportunity to assist you and provide a solution.

Try these steps:

1. Power Reset (the right way)

Even if you’ve tried before, do this methodically:

Turn off the printer.

Unplug all cables (power + USB/network).

Open the scanner lid and gently move the scanner bar all the way to the right and then left.

Check for:

Paper debris

Loose plastic bits

Dirt or dried ink

Close everything.

Plug the power cable directly into a wall outlet (no surge protector).

Power it back on.

2. Check the Scanner Light Path

Open the scanner lid and observe when you turn on the printer:

Does the scanner light turn on and attempt to move?

If it makes a grinding/jumping sound, that could mean a misaligned belt or dirty encoder strip.

3. Use HP Smart App Diagnostics

In HP Smart, go to your printer > Settings > Advanced Settings > Printer Reports > Print Status Report and Scanner Quality Report.

If it says “Scanner busy” or stalls — it may still be locked from the last failed job.

4. Check for Scanner Lock (if present)

Some printers have a scanner lock switch (especially during shipping). Make sure it's unlocked. It’s usually a small sliding tab near the scanner bed or underneath the lid.

I hope this helps.
