We're thrilled to have the opportunity to assist you and provide a solution.
The E3 error message typically indicates a paper jam or a carriage jam. Here are some steps to resolve this issue for your HP Smart Tank 5102 All-in-One Printer:
Check for Paper Jams:
- Turn off the printer and unplug it from the power source.
- Carefully inspect the input and output trays for any jammed paper. Remove any bits of paper or debris found.
- Open the front cover and check inside the printer for any stuck paper. Remove it gently if you find any.
Inspect the Carriage:
- Open the ink cartridge access door.
- Check if the print carriage can move freely from one side of the printer to the other. If it is stuck, do not force it.
- Gently move the carriage manually to see if it has any obstructions.
Reset the Printer:

- Unplug the power cord from the back of the printer and from the wall outlet.
- Wait for at least 60 seconds, then plug it back in.
- Turn on the printer and check if the error message clears.
Check for Loose or Missing Cartridges:
- Ensure that all ink cartridges are properly installed in their respective slots.
- Remove each cartridge and reinstall them to make sure they are seated correctly.
Update Firmware:
- Sometimes updating the printer firmware can resolve such issues. Make sure your printer's firmware is up-to-date.
Hope this helps!
