HP Printer Error Code 11 — What It Means & How to Fix It

What Does This Error Mean?

Error 11 means your HP printer has run out of paper. The paper tray is empty or the printer cannot detect any paper loaded. This is one of the simplest errors to fix — just reload the paper tray and press Continue.

Affected Models

HP LaserJet 4
HP LaserJet 4 Plus
HP LaserJet 5
HP LaserJet 5L
HP LaserJet 6L

Common Causes

The paper tray is completely empty and needs to be refilled
Paper is in the tray but not seated correctly against the guides
The paper stack is too small for the printer's paper sensor to detect
Paper is curled or wrinkled, preventing the feed mechanism from gripping it
The paper size loaded does not match the size selected in the print job

How to Fix It

Open the paper tray and check if it is empty. If so, load a fresh stack of paper.

Use standard 20 lb (75 gsm) plain paper for best results. Avoid paper that is damp or wrinkled.
Fan the paper stack before loading it. Tap it on a flat surface to align the edges evenly.

Fanning separates sheets that may be stuck together, which is a common cause of feed errors.
Slide the paper firmly into the tray and adjust the guides so they are snug against the edges of the stack.

Loose guides let paper shift during feeding, which can cause the printer to lose track of the paper.
Press the Continue or Go button on the printer to clear the error and resume printing.

On older HP LaserJet models, this button may be labeled 'Online' or have an arrow icon.
If the error returns immediately, try loading paper into the manual feed slot instead of the main tray.

This helps you confirm whether the issue is with the tray sensor or the paper itself.

When to Call a Professional

Error 11 is almost always fixable at home by reloading paper. If the error keeps appearing even after correctly loading a full stack, the paper sensor may be faulty. A technician can diagnose and replace a paper sensor for $30 to $60. For printers still under HP warranty, contact HP Support at 1-800-474-6836.

Frequently Asked Questions

Why does my HP show error 11 when paper is already in the tray?

The paper may not be pushed in far enough for the sensor to detect it. Remove all paper, tap the stack to align it, and reload it firmly. Also make sure the paper guides are snug — not too tight, not too loose.

Does paper type or weight affect error 11?

Yes. Very thin paper or very heavy cardstock can confuse the paper sensor. HP printers are designed for standard 20–24 lb (75–90 gsm) paper. If you are using a specialty paper, try standard paper to see if the error clears.

Can I print from the manual feed tray to avoid this error?

Yes. Most HP LaserJet models have a manual or multipurpose feed slot. You can load a few sheets there and select it as the paper source in your print settings. This is a good workaround while you diagnose the main tray.
