What is Xerox Printer Error 49.XX?

Error 49.XX is a generic internal software or print job error that often appears on the printer’s display. The “XX” refers to a sub-code that gives more specific details about the problem, but in most cases, it relates to:

• Corrupted print jobs

• Incompatible or outdated printer drivers

• Firmware or software issues

• Network or USB communication errors

• Conflicts with PostScript commands in complex print jobs

This error is common on Xerox multifunction printers and laser devices.

Common Causes of Error 49.XX

1. Corrupted Print Jobs: A large or complex file, especially PDFs, can trigger the error.

2. Outdated Printer Drivers: Using incompatible drivers on Windows or macOS may cause internal errors.

3. Firmware Issues: Old or corrupted firmware can conflict with new print jobs.

4. Network or USB Communication Problems: Interrupted data transfer can lead to error 49.XX.

5. Unsupported Commands: Advanced PostScript commands in certain documents may not be recognized.

Step 1: Clear the Printer Queue

Often, the error is caused by a problematic print job. Clearing the print queue can resolve the issue:

On Windows:

1. Open Settings > Devices > Printers & Scanners

2. Select your Xerox printer and click Open Queue

3. Cancel all pending print jobs

On Mac:

1. Open System Settings > Printers & Scanners

2. Select your printer and open the print queue

3. Delete all pending jobs

After clearing, restart the printer to reset its memory.

Step 2: Restart the Printer

A simple restart can often clear temporary internal errors:

1. Turn off the printer

2. Unplug it from the power source

3. Wait 30–60 seconds

4. Plug it back in and turn it on

This clears the printer’s memory and resets internal software.

Step 3: Update Xerox Printer Driver

Outdated or incompatible drivers are a frequent cause of error 49.XX:

1. Visit the official Xerox support website

2. Download the latest driver for your printer model

3. Install the driver following instructions for Windows 10/11 or macOS

4. Restart your system after installation

Tip: Using the Xerox Global Print Driver can help avoid driver-specific conflicts.

Step 4: Update Printer Firmware

Firmware updates often fix internal errors:

1. Access the printer’s Embedded Web Server (EWS) by entering its IP address in a browser

2. Navigate to Firmware or Software Updates

3. Download and install the latest firmware

4. Restart the printer

Keeping firmware updated ensures compatibility with modern print jobs.

Step 5: Check Network or USB Connection

Intermittent communication can trigger error 49.XX:

• Ensure cables are securely connected (USB or Ethernet)

• For Wi-Fi, confirm the printer is on the correct network

• Restart your router and printer if using a network connection

• Avoid sending large files over unstable networks

Step 6: Simplify Problematic Print Jobs

If the error occurs with a specific file:

• Try printing a smaller or simpler document

• Convert PDFs to images or reduce complexity

• Disable advanced PostScript features if available

• Print in smaller batches rather than sending a large document at once

Step 7: Perform a Factory Reset (Last Resort)

If the error persists after all steps, a factory reset may help:

1. Access the printer Menu > System Settings > Reset

2. Choose Factory Default

3. Confirm the reset

Warning: This will erase all customized settings, so document network and user preferences before performing.
