All the ways we help, in one place

1. Confirm your printer and your computer or phone are on the same Wi-Fi network — not a guest network.
2. Restart the printer's wireless radio: most models have a Wi-Fi button or a setting menu to toggle it off and on.
3. Re-run the printer's built-in wireless setup wizard and re-enter your network password.
4. If you recently changed routers, most printers need to be re-added as a new device rather than just reconnected.

1. Check that the printer is powered on and has no error lights or messages on its display.
2. On Windows or macOS, open your printer queue and clear any stuck print jobs — a stalled job can mark the whole printer offline.
3. Remove the printer from your device list and add it again so your computer picks up a fresh connection.
4. If it goes offline repeatedly rather than once, that pattern usually needs a live session to sort out properly.

Error codes and blink patterns are specific to each manufacturer and model, so there's no universal chart that covers all of them accurately. The fastest way to get an accurate read on yours:

1. Note the exact code or count the blink pattern shown on the printer.
2. Check the printer's own display menu — many models show a short description alongside the code.
3. Have your model number ready and call in — a technician can confirm exactly what your code means and the safe fix.
