Frequently Asked Questions - LaserJet Enterprise M631h HP
How do I load paper into the HP LaserJet Enterprise M631h?
Open the input tray by pulling it out. Adjust the width guides to the paper size. For A4 or Letter, place the paper in the tray with the print side facing down. Do not overload the tray; keep the stack below the maximum fill line. Slide the tray back into the printer until it clicks. The control panel will indicate the tray status.
How do I replace the toner cartridge?
When the toner is low, the control panel shows a warning. Open the front door and remove the old cartridge. Remove the new cartridge from its packaging, shake it side to side about 10 times to distribute toner, and insert it. Close the front door. The printer will prepare the cartridge and print a page to clean the system. See the HP JetIntelligence manual for detailed steps.
How do I clear a paper jam in the HP LaserJet Enterprise M631h?
Turn off the printer. Open the front door and check for jams in the toner cartridge area. Remove the cartridge if necessary. Check the output bin and the duplexer (rear access). Gently pull out any jammed paper in the direction of paper flow. Do not pull against the path. Close the doors and turn the printer on. The control panel will reset after the jam is cleared.
How do I connect the printer to a network?
Connect an Ethernet cable from the printer to your router or switch. On the control panel, press Network Setup or Wireless Setup depending on the model. For wired, choose DHCP or static IP assigning. For wireless, search for your SSID and enter the password. Use the HP Smart Administrator or the control panel to confirm the connection.
How do I enable automatic duplex printing on the HP LaserJet Enterprise M631h?
In the printer driver, open the Printing Preferences dialog. Go to the Finishing or Layout tab and select Print on Both Sides (automatic). Choose the binding orientation (long edge or short edge). Save the settings. The printer automatically flips the paper internally, so no manual intervention is needed.
How do I perform a factory reset on the printer?
On the control panel, press the Home button, then tap Setup or General. Look for Factory Reset under the Security or Administrative menu. If you cannot find it, navigate to Settings > General > Reset. Confirm the reset. This restores original settings and clears network configurations, so use it carefully.
How do I clean the HP LaserJet Enterprise M631h?
To clean the exterior, unplug the printer and wipe it with a damp, lint-free cloth. Do not use abrasive cleaners. For internal cleaning, go to Support Tools on the control panel and select Clean to run a cleaning page. This removes toner residue from the paper path. Clean the fuser area only if specified by a service technician, as it can be hot.
How do I update the firmware on the printer?
Download the Firmware Upgrade Utility from the HP website. The printer must be connected via network or USB. Use the HP Embedded Web Server (enter the printer IP in a browser) and go to General > Firmware to upload the file. Alternatively, run the executable and select the printer. Keep the printer powered on during the update and do not interrupt the process.
How do I install the printer driver on Windows?
Download the HP Universal Print Driver (UPD) or the specific M631 series driver from HP.com. Run the installer and choose Network connection if the printer is on the network. Windows will detect the printer automatically if it is on the same subnet. Follow the on-screen instructions to add the port and finish. Test by printing a configuration page.
How do I troubleshoot faded prints?
Faded prints can be caused by low toner, wrong paper settings, or a dirty fuser. First, check the toner level from the control panel. If low, replace the cartridge. Next, verify the paper type matches the driver setting (e.g., ordinary paper vs. recycled). Run a cleaning page. If the issue persists, inspect the fuser for damage and contact support. Adjust the print density setting if available.
