## **What is a Paper Mismatch Error?**

A **Paper Mismatch Error** occurs when the **paper size or type** loaded into the printer does not match the **paper settings** configured in the print dialog box, printer control panel, or printer software. The error may appear on the printer screen, in HP Smart App, or on your PC as:

* "**Paper Mismatch Detected. Load Correct Paper and Try Again.**"
* "**Paper Size or Type Mismatch. Printing Stopped.**"
* "**Mismatch between paper in tray and print job settings.**"

## **Common Causes of Paper Mismatch on HP Smart Tank Printers**

Here are the most frequent triggers of this issue:

1. **Wrong Paper Size Set in Driver or Printer Settings**
2. **Paper Type Mismatch (e.g., Glossy vs Plain Paper)**
3. **Misaligned Paper Guides in the Input Tray**
4. **Outdated or Corrupt Printer Driver**
5. **Incorrect Settings in HP Smart App**
6. **Firmware Bugs or Errors**
7. **Default Print Settings in Windows or macOS**

Let’s break down each cause and its solution.

## **Solution 1: Check and Adjust Paper Size in Printer Settings**

### 🔧 How to Do It:

1. Go to the **Control Panel** on the printer or open **HP Smart App**.
2. Navigate to **Paper Settings > Paper Size**.
3. Make sure it matches the actual paper in the tray (e.g., **A4, Letter, Legal**).
4. Save and confirm.

**Note:** Many HP Smart Tank printers default to **A4** while users in the US use **Letter size** paper. This mismatch often causes the issue.

## **Solution 2: Match Paper Size in Print Dialog (Windows/macOS)**

When printing from an application like MS Word or Adobe PDF:

1. Press **Ctrl+P** or click **File > Print**.
2. Select your **HP Smart Tank Printer**.
3. Click **Printer Properties** or **Preferences**.
4. Under **Paper/Quality** or **Advanced**, make sure **Paper Size** matches the one in the printer tray.

For example:

* Tray has Letter size paper? Choose **Letter 8.5 x 11 inches**.
* Tray has A4? Select **A4 210 x 297 mm**.

## **Solution 3: Update or Reinstall the HP Smart Tank Printer Driver**

Sometimes, a **corrupt or outdated driver** causes persistent mismatch errors.

### 🔄 Steps to Update Driver:

**On Windows:**

1. Go to **Device Manager > Printers**.
2. Right-click your **HP Smart Tank Printer**.
3. Select **Update Driver > Search Automatically**.
4. Alternatively, download the latest driver from [support.hp.com](https://support.hp.com).

**On macOS:**

1. Go to **System Settings > Printers & Scanners**.
2. Remove and re-add the HP printer to auto-install the correct driver.

## **Solution 4: Reset the Printer to Default Settings**

If you’ve changed many settings or installed a firmware update, a reset can resolve mismatches.

### 🔁 How to Reset:

1. On the **printer control panel**, go to **Settings**.
2. Choose **Restore Defaults** or **Reset All Settings**.
3. Confirm when prompted.

⚠️ **Note:** This will erase saved Wi-Fi credentials and preferences.

## **Solution 5: Correct Paper Type Settings**

Even if the paper size is correct, setting the wrong **paper type** can trigger mismatch errors.

For example:

* You load **plain paper**, but print settings are set to **Glossy Photo Paper**.

### ✔ How to Fix:

1. Go to **Print Settings > Paper Type** in your app or printer preferences.
2. Select the correct type: **Plain Paper**, **Photo Paper**, **Envelopes**, etc.
3. Save and reprint.

## **Solution 6: Align Paper Guides in the Input Tray**

Physical misalignment can confuse sensors and cause errors.

### 📏 Proper Loading Tips:

* Pull out the input tray and **align the sliders** snugly against the paper stack.
* Avoid overloading.
* Make sure the paper isn’t bent, curled, or damp.
* Fan the paper stack to prevent sticking.

## **Solution 7: Update Printer Firmware**

HP often releases firmware updates to resolve bugs like persistent mismatch errors.

### 🌐 Steps to Update:

1. Download and install **HP Smart App** from [123.hp.com](https://123.hp.com).
2. Open the app and connect your HP Smart Tank printer.
3. Go to **Printer Settings > Advanced Settings > Printer Updates**.
4. Click **Check for Updates**.

Let the firmware update complete without interruption.

## **Solution 8: Disable “Prompt for Paper Type/Size” Setting**

By default, HP Smart Tank printers may prompt you every time you load new paper.

### 🛑 Disable This Prompt:

1. Open the **Embedded Web Server (EWS)**:

* Find your printer's IP by printing a **Network Configuration Page**.
* Open a browser and go to the IP address (e.g., [http://192.168.1.25](http://192.168.1.25)).
2. Navigate to **Settings > Paper Handling**.
3. Turn off the setting: **Prompt for Paper Size and Type**.

## **Solution 9: Use HP Smart App to Align Settings**

The HP Smart App often overrides OS print commands. Ensure it’s configured properly.

### 🛠 How to Check:

1. Launch the **HP Smart App**.
2. Go to **Print Settings > Paper Handling**.
3. Choose correct **size, type, and tray**.
4. Save preferences as default.

## **Solution 10: Set the Same Paper Size as Default in Windows/macOS**

Default system-level settings may conflict with app-specific settings.

### ✅ On Windows:

1. Go to **Control Panel > Devices and Printers**.
2. Right-click your printer > **Printing Preferences**.
3. Set **Paper Size** to match tray content.
4. Apply and save as default.

### ✅ On macOS:

1. Open **Printers & Scanners** in System Settings.
2. Select your printer.
3. Click **Options & Supplies > Driver**.
4. Confirm paper size in **Print Queue Settings**.

## **Additional Tips to Prevent Paper Mismatch Errors**

### 📝 Best Practices:

* Always use supported paper sizes (Letter, A4, Legal, etc.)
* Avoid mixing paper types in a single tray.
* Use genuine HP ink and paper for best compatibility.
* Keep firmware and drivers updated monthly.
* Avoid using third-party print utilities that might override driver settings.

## **Model-Specific Troubleshooting for HP Smart Tank Series**

Here are a few notes for popular Smart Tank models:

* Use HP Smart App to configure paper tray behavior.

### 🔹 **HP Smart Tank 7001/7002**
