If you’re an Epson printer user, you might have encountered the frustrating “Paper Mismatch” error message. This common issue typically arises when the printer’s settings do not align with the paper loaded in the tray, or there is a mismatch between the paper size selected on the printer and the paper actually loaded. While this may seem like a simple problem, it can hinder your ability to print efficiently. But don’t worry, this blog will guide you through understanding the cause and provide simple troubleshooting steps to resolve it.
What is the “Paper Mismatch” Error?
The “Paper Mismatch” error occurs when the printer detects a difference between the paper size or type settings in the printer and the actual paper loaded in the tray. It could also happen if the software on your computer doesn’t match the settings on the printer itself.
When this happens, the printer refuses to print and displays the error message to alert you of the discrepancy.

Common Causes of the Paper Mismatch Error
- Incorrect Paper Size Settings: One of the most common reasons for the paper mismatch error is that the paper size set in the printer’s settings doesn’t match the size of the paper loaded in the tray. For example, you might have A4 paper in the tray, but the printer is set to print on Letter-sized paper.
- Incorrect Paper Type Settings: The error can also be triggered if the paper type set on the printer does not match the actual paper type in the tray. For example, if you’ve loaded glossy paper but the printer is set to plain paper, the mismatch error may occur.
- Printer Tray Issues: Sometimes, if the paper is not correctly aligned or is placed incorrectly in the printer’s paper tray, it could cause a mismatch error. The sensors inside the printer may not detect the paper correctly, leading to an error.
- Software Mismatch: Another cause can be a mismatch between the printer settings in your computer’s print dialog box and the settings on the printer itself. If you’ve selected a different paper size or type on the computer compared to what’s loaded in the printer, the error will appear.
How to Fix the “Paper Mismatch” Error
1. Check the Paper Size and Type
- First, make sure the paper loaded in the tray matches the paper size and type selected in the printer settings.
- On your printer’s control panel, go to the paper settings and ensure the correct paper size (A4, Letter, etc.) and type (Plain, Glossy, etc.) are selected.
- Verify that the paper in the tray is properly aligned and loaded according to the printer’s specifications.
2. Align Paper Correctly in the Tray
- Double-check the alignment of the paper in the printer’s paper tray. Ensure that the paper is not skewed or jammed.
- If necessary, adjust the paper guides in the tray to ensure the paper is seated correctly and aligned with the printer’s sensors.
3. Update Printer Driver and Software
- Sometimes outdated or incorrect drivers can cause the printer to misinterpret the paper size and type. Ensure that you have the latest printer drivers installed on your computer.
- Visit the official Epson website and download the latest driver for your printer model.
4. Check Your Computer’s Print Settings
- When you send a print job from your computer, double-check the print settings. In the print dialog box, make sure that the paper size and type are correctly set to match what is loaded in the printer tray.
- You can also check the print preferences on your computer to ensure they are in sync with the printer’s configuration.
5. Reset Printer Settings
- If the above solutions don’t resolve the error, try resetting your printer’s settings to factory defaults. This will clear any conflicting configurations that might be causing the issue.
- Refer to your printer’s user manual for instructions on how to perform a reset.
6. Try a Different Paper Type or Size
- If the issue persists, consider trying a different paper size or type. Sometimes, the printer may struggle to detect certain paper types due to weight, texture, or compatibility issues.
- Use standard, recommended paper for your printer model to avoid such errors.
