HP DESKJET-3639 user manual

There could be several reasons why your HP 3630 is not printing. Here are a few common troubleshooting steps to help identify and fix the issue:
1. Check ink/toner levels: Make sure the ink or toner cartridges have enough ink or toner to print. If they are low or empty, replace them.
2. Paper jams: Check for any paper jams in the printer. Open the printer cover and remove any stuck or wrinkled paper. Make sure the paper is loaded correctly in the tray.
3. Connectivity issues: Ensure that the printer is properly connected to your computer or network. If it's a wireless printer, check the Wi-Fi connection and ensure both devices are on the same network.
4. Printer queue: Sometimes, print jobs get stuck in the queue, preventing further printing. Open your printer settings on your computer and clear any pending print jobs.
5. Printer drivers: Ensure that you have the latest printer drivers installed on your computer. Outdated or incompatible drivers can cause printing problems. You can download the latest drivers from the HP website.
6. Restart printer and computer: Try turning off the printer and unplugging it from the power source. Also, restart your computer. After a few minutes, reconnect the printer and try printing again.
If none of these steps resolve the issue, you may need to consult the HP support website or contact their customer support for further assistance.
