Hello @LindiLou65, and welcome to the HP Support Community!
Thanks for posting your question. I'm here to help you get things back on track.
The "!" error light on your HP Smart Tank 5108 typically indicates a general error that could be related to paper, ink, connectivity, or hardware. Since you've successfully printed a few pages, let's walk through some steps to identify and resolve the issue:
Check for Paper Jams or Feed Issues
- Open all access doors and trays.
- Remove any jammed paper or debris.
- Ensure paper is loaded correctly and not curled or damp.
Check Ink Levels and Cartridges
- Make sure all ink tanks have sufficient ink.
- Ensure the ink tank caps are properly closed.
- If you recently refilled ink, allow the printer a few minutes to recalibrate.
Power Cycle the Printer
- Turn off the printer.
- Unplug it from the power source for 60 seconds.
- Plug it back in and turn it on.
This can reset temporary errors.
Update Printer Firmware
Outdated firmware can cause unexpected behavior.
- Download and install the latest firmware from HP: Official HP® Support
Check for Error Messages on HP Smart App
If you're using the HP Smart app, it may show a more specific error message.
I hope the information shared has been useful and resolves your concern.
Wishing you a smooth and hassle-free experience ahead!
