Why Does My HP Envoy 6400 Keep Checking Paper Size? Here's How to Fix It

Select Language:

If your HP ENVY 6400e all-in-one printer isn’t recognizing your paper correctly or keeps showing paper size errors, don’t worry. Here’s a simple step-by-step guide to fix this issue and ensure your printer reads your paper settings accurately.

First, you’ll want to check the media loaded into the printer. Turn on your printer and follow the instructions in the user guide on page 17 to load the correct type and size of paper. Make sure the paper is aligned properly and the tray is not overfilled.

Next, you need to tell the printer what kind of paper you’re using. The printer automatically detects paper size, but sometimes it gets it wrong. To fix this, refer to page 23 of the user guide to change the default paper size detection. This setting can often be adjusted through the Embedded Web Server (EWS) if your printer is connected to Wi-Fi.

To access the EWS, find your printer’s IP address (you can usually get this from the printer’s network menu or print a network configuration page). Then open a web browser on your computer, type that IP address into the address bar, and press Enter.

Once logged into the EWS, navigate to the settings for paper management. Usually, this is under “Settings” > “Preferences” > “Tray and Paper” or similar options, depending on your model. Here, you can select or confirm the correct paper size and type, then save your changes by clicking “Apply.”

If you’re connected to a network and want to manage the settings directly from your router or network interface, you can do so by entering the printer’s IP address into your browser, then following similar steps to adjust paper settings.

If your print jobs still don’t print correctly after these adjustments, check the application you’re printing from. Make sure the print setup specifies the correct paper tray and size. If it’s set to automatic, and problems persist, manually select the appropriate tray in your print options.

Remember, some printers have a default PIN to access the EWS. If prompted, check the back or inside of the printer (near the ink access area) for this PIN, or consult your user guide for more info.
