If your Kyocera ECOSYS M2640idw multifunction printer has lost its network connection, keeps changing its IP address, or you simply can't locate its current network address, you're not alone. IP address issues are among the most common network printer problems that our printer repair team encounters. Whether you need to set a static IP, find the current DHCP-assigned address, or resolve connectivity drops after router changes, this troubleshooting guide provides concrete steps to get your ECOSYS M2640idw back online and reliably accessible from all your devices.
Finding Your Current Kyocera ECOSYS M2640idw IP Address
Before you can fix printer connectivity problems, you need to know what IP address your M2640idw is currently using—or if it has one at all. Here are the most reliable methods to locate it.
1
Print a Network Status Page: On the ECOSYS M2640idw control panel, press the System Menu button, navigate to Report, then select Network Status. Press Start to print. The first page will clearly display the IPv4 Address, Subnet Mask, and Default Gateway under the TCP/IP section. If the IP address shows 0.0.0.0 or 169.254.x.x, your printer isn't successfully connecting to your network.
2
Check the Control Panel Display: From the home screen, press System Menu, then Network, then TCP/IP Settings, then IPv4. The current IP address will be displayed here. You can also view whether DHCP is enabled or if a static IP is configured. This method is faster than printing a report but shows less diagnostic information.
3
Use Kyocera Net Viewer or Command Center: If the printer was previously configured, install Kyocera Net Viewer on a Windows PC on the same network segment. It will auto-discover Kyocera devices. Alternatively, try accessing the printer's web interface by entering educated guesses (like your router's IP range with common endings) into a browser. The ECOSYS M2640idw uses Command Center RX for web management.
⚠️ Important: Avoid repeatedly power-cycling your ECOSYS M2640idw to force an IP renewal—this can corrupt the network firmware settings. Instead, use the control panel menus or perform a proper network reset through System Menu > Network > Network Reset. After any reset, wait a full 2 minutes before attempting reconnection.
Configuring a Static IP for Stable Connectivity
DHCP-assigned addresses change over time, causing driver connection failures and scan-to-email interruptions. Setting a static IP is the most reliable printer support solution for business environments.
4
Reserve an IP in Your Router First: Access your router's admin panel (typically 192.168.1.1 or 192.168.0.1), find the DHCP reservation or Address Reservation section, and reserve an IP outside the dynamic pool for the M2640idw's MAC address. The MAC address is printed on the network status page from Step 1. This prevents IP conflicts even before configuring the printer itself.
5
Enter Static IP on the Printer: On the M2640idw control panel, navigate to System Menu > Network > TCP/IP Settings > IPv4. Change Boot Method from DHCP to Static. Enter your chosen IP address, Subnet Mask, Default Gateway, and at least one DNS server (typically your router's IP or 8.8.8.8). Press OK and restart the printer. Verify by printing another network status page.
6
Update Driver Ports on All Computers: On each PC that prints to this device, open Devices and Printers, right-click the Kyocera ECOSYS M2640idw, select Printer Properties, go to the Ports tab, and edit the Standard TCP/IP Port to match your new static IP. For WSD or network-discovered installations, you may need to delete and recreate the printer using the IP address directly for maximum stability.

Why does my Kyocera ECOSYS M2640idw IP address keep changing?
Your router's DHCP server is assigning a new lease each time. This happens when DHCP lease times are short, when the printer is offline during lease renewal, or when multiple access points create network confusion. The permanent fix is configuring a static IP or DHCP reservation as described in Steps 4-5 above.
Can I set the IP address through the Kyocera Command Center web interface?
Yes, if you can access it. Enter the current IP address in any web browser, log in with Admin credentials (default is Admin/Admin on many units, though your IT department may have changed this). Navigate to Basic > TCP/IP to modify settings. However, if you've lost the IP entirely, you must use the physical control panel first.
What IP settings work best for the ECOSYS M2640idw in a small office?
Use an IPv4 address in your router's range but outside its DHCP pool—for example, if your router distributes 192.168.1.100 through 192.168.1.200, assign 192.168.1.50 to the printer. Set Subnet Mask to 255.255.255.0, Default Gateway to your router's IP, and DNS to your router or 8.8.8.8. This configuration eliminates virtually all troubleshooting related to address conflicts.
