Printer or scanner not connecting? Start with these safe checks.

Check visible status and the selected device.

Confirm the printer or scanner is powered on, note any message on its display, and check that the app is using the intended device. If it is a printer, notice whether the problem happens in one app or everywhere you try to print.

Record the exact message.

Write down the full error or status wording, when it began, and whether it happens every time. “Offline,” “not found,” a job that stays pending, and a scanner missing from the app are different symptoms; avoid guessing at the cause.

See whether the device is already listed.

Open your computer’s printer or scanner settings and note whether the device appears there. For a new setup, use the operating system’s add-device flow or the manufacturer’s instructions for your exact model and system version.

Check driver prompts at their source.

If setup asks for a driver or software, use current guidance from your operating-system maker or the printer manufacturer. Record the driver name or prompt, and avoid download ads or third-party driver sites. Do not remove a working setup just to try another package.

Look at the queue without clearing it.

Open the selected printer’s queue and note whether a job is waiting, paused, or showing an error. Check whether the printer is marked offline or paused. Keep the job in place while you record what you see; cancelling the queue can remove documents you still need.

Compare the printer’s status with its display.

If the computer says “offline” but the printer is on, note the printer display and how it connects. For paper, ink, cover, or connection messages, follow the maker’s instructions for that message instead of repeatedly resending the job.

Compare the network names.

Check the network name shown by the printer and the one used by your computer. If they differ, note that before changing anything. Some homes have separate network names or guest networks; use the printer maker’s directions before changing router or security settings.

Note whether another device can see it.

If another device is already available, note whether it can find the printer or scanner on the same network. This comparison can help describe the problem, but it cannot prove where the fault is.

Look for the scanner in device settings.

Check your computer’s printer and scanner list. On some systems, the scanner function appears under the multifunction printer; on others it is listed separately. If it is missing, follow the official scanner setup instructions for the model and connection type.

Check the scan app and source selection.

If the scanner is listed, open the operating system’s scan app and confirm it is selected. For a test, match the source setting to where the page is placed—flatbed or document feeder—and note the result.

Write down what you know and already tried.

Include the printer or scanner make and model, computer or phone and operating-system version, connection type (USB, Wi-Fi, Ethernet, or Bluetooth), exact error text, when the issue began, and checks already tried with their results. Do not include passwords, verification codes, or private document contents.
