The “E3” error code on an HP printer typically indicates a paper jam. When this error appears, it means that the printer’s paper path is obstructed, and the printer cannot properly load or feed paper. The most common causes of the E3 error code are:

Paper jam: A piece of paper might be stuck inside the printer, blocking the paper path.

Improper paper placement: The paper might not be loaded correctly in the input tray, or it could be of the wrong size or type for the printer.

Dirty or damaged rollers: The printer’s rollers, responsible for picking up and feeding paper, might be dirty or damaged, causing paper feed issues.

Foreign objects: Objects like staples, paper clips, or debris may have accidentally fallen into the printer, obstructing the paper path.

To resolve the E3 error code, follow these steps:

Turn off the printer: Press the power button to turn off the printer and disconnect it from the power source.

Open the printer access door: Carefully open the printer access door or input tray and inspect for any visible paper jams or foreign objects.

Remove any jammed paper: Gently pull out any jammed paper in the direction of paper path movement. Avoid tearing the paper, and make sure all fragments are removed.

Check the paper path: Examine the paper path for any torn pieces of paper or foreign objects and remove them if found.

Clean the rollers: If you suspect that the rollers are dirty or damaged, follow the printer’s manual instructions to clean them properly.

Load paper correctly: Ensure that you load the correct size and type of paper into the input tray, and adjust the paper guides to fit the paper properly.

Restart the printer: After checking and clearing any paper jams or obstructions, reconnect the printer to power and turn it on. The error should be cleared.

If the E3 error persists even after following these steps, there might be a more complex issue with the printer’s hardware or sensors. In such cases, it’s best to reach out to HP printer technical support UK or take the printer to an authorized service center for further assistance and repair.
