Kyocera Error C0180 — What It Means & How to Fix It
By Ryan Green · Updated August 2026 · Independent guide · PrinterCare USA LLC (not affiliated with any printer manufacturer)
The C0180 error on Kyocera multifunction printers is frustrating because it prevents normal operation and suggests a deeper communication problem between your device and its stored configuration data. This error typically appears when you attempt to scan, copy, or access network functions, leaving you unable to complete critical business tasks.
The good news is that most C0180 errors stem from temporary configuration conflicts that clear up with straightforward troubleshooting steps you can perform yourself in under thirty minutes. We'll walk you through each solution from simplest to most advanced so you can get back to work as quickly as possible.
How to fix it — step by step
- Power cycle the printer completely. Turn off your Kyocera printer using the power button, then unplug the power cable from the wall outlet and wait for a full two minutes. This clears temporary memory errors that may have triggered the machine number mismatch detection. Plug the device back in and power it on, then allow it to complete its startup sequence fully before attempting any operation.
- Check your network connection status. Navigate to the printer's home screen, then select Settings or System Settings depending on your model. Look for the Network Status or TCP/IP section and verify that the printer has an active IP address and is connected to your network. If the network shows as disconnected or has no IP address assigned, power cycle your router as well and wait for the printer to reconnect.
- Clear the printer's network settings cache. From the main menu, go to Settings, then Network or Administrator Settings. Select Reset Network Configuration or similar wording on your specific model. The printer will ask for confirmation and may require the administrator password, which is often the default code like 12345 or 00000 depending on your setup. Allow the printer to restart after clearing the cache.
- Update or verify the printer's firmware version. Visit the Kyocera support website and search for your exact printer model number, which appears on the device's information label. Download any available firmware updates to a USB drive formatted as FAT32. Insert the USB into the printer's USB port, navigate to Settings, and select Firmware Update or Device Update, then follow the on-screen prompts to install the latest version.
- Reset the machine number and configuration data. Access the Service or Advanced Settings menu by holding down the Settings button for five seconds or using the administrator login. Look for options labeled Machine Number Reset, Configuration Reset, or Factory Reset for Network Settings. Select the appropriate option, enter your administrator password if prompted, and allow the printer to restart and rebuild its configuration data from scratch.
- Reconfigure your printer on the network. After the reset completes, go back to Settings and Network Configuration to manually set up your network connection again. If you use DHCP, the printer should automatically obtain a new IP address within one minute. If you use a static IP address, enter the correct values for IP address, subnet mask, and gateway as provided by your IT administrator or network setup documentation.
- Run the printer's built-in diagnostic test. From the main menu, select Service or Tools, then look for Diagnostics, Self Test, or Device Health Check. Run the full system diagnostic scan and review the results to confirm that all hardware components and network functions are reporting healthy status. Document any error codes that appear in the diagnostic report.
- Contact Kyocera support for remote assistance if needed. If the C0180 error persists after completing all previous steps, contact a Kyocera certified technician or support partner for remote diagnostics, which typically costs around $49 for a single session. The technician can access your printer remotely to identify configuration issues in the firmware that simple resets cannot resolve, and they can apply a permanent fix without requiring an expensive service call.

Frequently asked questions
What does the machine number mismatch error actually mean on my Kyocera?
The machine number is a unique identifier stored in your printer's firmware that should match the network and device configuration data. When these values become corrupted or out of sync, usually due to improper shutdowns or network interruptions, the printer throws the C0180 error as a safety measure. This mismatch prevents the printer from executing functions reliably, which is why it blocks scanning and copying operations.
Will I lose any of my saved settings or documents if I do a factory reset?
A network configuration reset or factory reset for network settings will erase stored network credentials, static IP addresses, and some device preferences, but it will not delete user documents, scan-to-folder destinations, or finisher settings on most Kyocera models. Before you reset, take a screenshot of your current network settings so you can reconfigure them quickly. Check your specific printer's user manual if you have custom settings you need to preserve.
Can the C0180 error indicate a hardware failure that requires parts replacement?
The C0180 error is almost always a software configuration issue rather than a failed hard drive or hardware component, so parts replacement is rarely necessary. However, if the error persists after all troubleshooting steps and a remote technician confirms the diagnosis, there could be a failing firmware chip or network card that requires professional replacement. In such cases, repair costs can range from $150 to $300 depending on the component.
Why does my Kyocera show C0180 only when I try to use the scanner or network functions?
The machine number verification only occurs when the printer attempts to access network features or the scanner engine, so the error appears specifically during those operations rather than during simple copying. This happens because scanning and network functions require more extensive communication with the stored machine configuration than basic printing does. Once you complete the reset steps, all functions should work equally well.
