HP LaserJet Pro P1102 Error Codes

Understanding the P1102 status lights

The HP LaserJet Pro P1102 does not have a conventional display for showing detailed error codes.

Instead, many printer conditions are communicated through the control-panel status lights. If your P1102 stops printing, checking which lights are on or blinking can help identify what needs attention.

Start with the basic checks

Before troubleshooting a specific light condition:

1. Make sure the printer is connected to power and switched on.
2. Check that paper is loaded correctly.
3. Look for jammed paper.
4. Make sure the print-cartridge door is completely closed.
5. Check that the toner cartridge is installed correctly.

After correcting anything you find, check whether the printer’s light pattern changes.

Attention light is blinking

A blinking Attention light indicates that the printer needs attention before it can continue normally.

Check for common causes such as:

• No paper or incorrectly loaded paper
• A paper jam
• An open print-cartridge door
• A toner cartridge that is not installed correctly
• Another condition preventing the printer from continuing

Correct the visible problem first and then check the printer again.

Check for a paper jam

A paper jam can stop printing and trigger an error-light condition.

If you find jammed paper:

1. Stop sending additional print jobs.
2. Carefully remove accessible jammed paper.
3. Check for torn pieces remaining in the paper path.
4. Reload the paper correctly.
5. Make sure the printer is completely closed.
6. Try printing again.

Avoid pulling forcefully on paper that does not move freely, as torn pieces can remain inside the printer.

Check the toner cartridge

If the printer appears to indicate a cartridge-related problem:

1. Turn the printer off.
2. Open the print-cartridge door.
3. Carefully remove the toner cartridge.
4. Check that any required packaging or sealing material has been removed.
5. Reinstall the cartridge correctly.
6. Close the cartridge door completely.
7. Turn the printer back on.

If the same condition returns, the toner cartridge may require further troubleshooting or replacement.

Make sure the cartridge door is closed

The P1102 may not operate normally if the print-cartridge door is not fully closed.

Open the door and check that the toner cartridge is seated correctly.

Then close the door firmly, making sure that nothing is obstructing it.

Printer has power but is not responding

If the printer has power but does not respond to a print job:

• Cancel any stalled print jobs.
• Turn the printer off.
• Wait briefly.
• Turn it back on.
• Check the USB connection.
• Try printing again.

If the same light pattern immediately returns, identify the underlying printer condition rather than repeatedly restarting the printer.

What if several lights are on or blinking?

Different combinations of status lights can indicate different printer states.

Do not assume that every blinking-light pattern represents the same problem.

Check the exact pattern shown on your printer and compare it with HP’s official troubleshooting information for the LaserJet Pro P1102 and P1100 printer family.

This is especially useful when the basic checks for paper, jams, the cartridge and the cartridge door do not explain the light pattern.

Still seeing an error?

If the same error-light condition remains after checking the paper supply, paper path, toner cartridge, cartridge door and USB connection, use HP’s official support resources below to identify the specific light pattern.

If HP’s troubleshooting indicates that the printer requires service, avoid dismantling internal printer components unless the procedure is specifically documented for users.
