Understanding Paper Jams
A paper jam occurs when a sheet of paper gets stuck inside the printer’s paper path. This can happen for various reasons, including:
- Overloading the paper tray: Placing too much paper in the tray can cause jams.
- Using the wrong paper type: Using paper that is too thick or too thin for your printer can lead to jams.
- Damaged paper: Crumpled, torn, or wet paper can easily jam the printer.
- Foreign objects: Paper clips, staples, or other objects can obstruct the paper path.
- Printer malfunction: In some cases, a mechanical issue within the printer can cause recurring jams.
Step-by-Step Guide to Unjamming Your HP LaserJet Pro M402dn
1. Turn Off the Printer and Disconnect Power
The first step is to safely power down your printer. Turn off the printer using the power button on the control panel. Then, unplug the power cord from the wall outlet. This ensures that there is no electricity flowing through the printer while you work.
2. Locate the Jam
Open the front cover of your printer. You may see the jammed paper immediately. If not, gently pull the paper tray out and look inside the paper path. The jammed paper may be visible in the tray, the rollers, or the output tray.
3. Carefully Remove the Jammed Paper
Important: Do not pull the jammed paper forcefully. This can damage the printer.
- If the paper is visible in the tray: Gently pull the paper out of the tray.
- If the paper is stuck in the rollers: Use your fingers to carefully guide the paper out of the rollers. If the paper is torn, try to remove as much as possible without pulling too hard.
- If the paper is stuck in the output tray: Remove the jammed paper from the output tray.
4. Inspect for Obstructions
Once you have removed the jammed paper, check the paper path for any foreign objects, such as paper clips, staples, or small pieces of paper. Remove any obstructions you find.
5. Clean the Paper Path
Use a soft, lint-free cloth to gently wipe away any dust or debris from the paper path. Pay particular attention to the rollers.
6. Reconnect Power and Turn on the Printer
Once you have completed the above steps, plug the power cord back into the wall outlet and turn the printer back on.
7. Test the Printer
Print a test page to ensure the printer is working properly. If the printer still jams, there may be a more serious issue, and you may need to contact HP support.
