HP Error 49.38.07 — What It Means & How to Fix It
Updated July 2026 · Independent PrinterCare USA support guide
Error 49.38.07 is one of the more frustrating HP firmware errors because it suggests your printer's internal communication system has failed partway through a process. This typically happens after a power interruption during a firmware update, a corrupted print job in the queue, or occasionally after a botched automatic update pushed overnight. The good news is that most occurrences can be resolved without sending your printer for depot repair.
This error is specific to HP's firmware architecture and means the printer has detected that its firmware components are not communicating properly. Unlike some error codes that point to a single culprit, 49.38.07 requires a methodical approach because it could stem from several different causes ranging from simple to more complex.
How to fix it — step by step
- Perform a Hard Reset of Your Printer. Turn off your HP printer completely using the power button, then unplug the power cable from the wall outlet. Wait for a full two minutes to allow all capacitors in the printer to discharge completely. Plug the printer back in, turn it on, and allow it to run through its full startup sequence without sending any print jobs for at least one minute.
- Clear the Print Queue on Your Computer. On Windows 11, open Settings, go to Devices, then Printers & Scanners, find your HP printer, click it, and select Remove device. On macOS, open System Settings, navigate to General, then Printers & Scanners, select your printer, and click the minus button. Restart your computer and reconnect the printer as a new device to clear any corrupted jobs.
- Check for Stuck Print Jobs in the Printer Memory. On your printer's control panel, navigate to Settings or Setup, look for Job Queue or Print Jobs, and delete any stuck or pending jobs you see listed. If your printer model has a Web Interface accessible through your network, log in via the printer's IP address and check the Job Queue there as well, clearing any entries that appear frozen or incomplete.
- Update or Recover Your Printer's Firmware Manually. Visit the official HP support website, enter your printer model number, and download the latest firmware file to your computer. On the printer's control panel, navigate to Settings, then Firmware Update or Device Firmware, and select the option to install from USB if available. Transfer the firmware file to a formatted USB drive, insert it into the printer, and follow the on-screen prompts to install the update without interruption.
- Reset the Printer to Factory Defaults. Access your printer's control panel menu and look for Settings, Tools, or Administration. Find the option labeled Restore Defaults, Reset All Settings, or Factory Reset, and confirm the action. This will erase all custom settings and network configurations, so be prepared to reconfigure wireless connectivity and any saved preferences afterward.
- Verify Network Connectivity and DHCP Assignment. Print a network configuration page by holding the power button or accessing the control panel menu and selecting Print Reports or Network Configuration. Check that your printer has been assigned a valid IP address in your network range and that it shows a stable connection. If the IP address shows as zero or invalid, restart your router and printer to force a new DHCP lease.
- Contact HP for Remote Diagnostics or Repair. If the error persists after all previous steps, visit the HP support website or call HP support directly to arrange a remote diagnostic session, which typically costs around $49 to $99 depending on your printer model and service tier. A technician can remotely access your printer's firmware logs to identify whether the issue requires a motherboard replacement or if additional firmware recovery steps are needed.

Frequently asked questions
Does error 49.38.07 mean my printer's motherboard is broken?
Not necessarily. While a failing motherboard can cause this error, the majority of cases stem from corrupted firmware, interrupted updates, or stuck print jobs that can be resolved through software recovery. A technician can review your printer's diagnostic logs remotely to determine if hardware replacement is actually required before you spend money on a new main logic board.
Will unplugging my printer during the hard reset cause permanent damage?
No, unplugging your printer for two minutes is a standard and safe troubleshooting step that allows the printer's memory to completely reset. Modern HP printers are designed to handle power interruptions, and a deliberate two-minute reset is very different from an accidental power loss during a firmware update, which is what likely caused your error in the first place.
Can I still print while error 49.38.07 is showing on the display?
In most cases, no. This error prevents the printer from processing new jobs because the firmware communication pathway is broken. Your printer will typically refuse to accept print jobs or respond to commands until the error is cleared, which is why it requires troubleshooting before normal operation can resume.
If I do the factory reset, will I lose my saved Wi-Fi password and settings?
Yes, a factory reset will erase all custom settings including your wireless network name, password, and any stored printer configurations like custom tray assignments. You will need to reconnect to your network and reconfigure any settings after the reset is complete, so have your Wi-Fi credentials available before you proceed.
