How to fix "Cannot connect with DHCP server .101 contact administrator" on a Ricoh MPC C4504 printer

The error "Cannot connect with DHCP server .101 contact administrator" on a Ricoh MPC C4504 copier/printer usually means the device is unable to obtain an IP address from the DHCP server. Here are some steps you can take to resolve this issue:
1. Check Network Cables
Ensure that the network cable is securely connected to both the printer and the network switch or wall jack.
If possible, try using a different cable or port to rule out a faulty connection.
2. Restart the Printer and Network Devices
Power off the Ricoh printer and unplug it for about 30 seconds.
Restart the network devices like routers, switches, or DHCP servers.
After restarting the network devices, power on the Ricoh printer.
3. Verify DHCP Server is Running
Make sure the DHCP server in your network (usually on a router or dedicated server) is up and running.
Check that there are enough available IP addresses in the DHCP pool for the printer to obtain one.
4. Check Printer Network Settings
On the printer control panel, go to System Settings Interface Settings Network.
Verify that DHCP is enabled (the printer should be set to automatically obtain an IP address).
If DHCP is disabled, enable it and reboot the printer to see if it can connect to the network.
5. Assign a Static IP Address
If DHCP is not working, you can try manually assigning a static IP address to the printer.
Go to System Settings Interface Settings IPv4 Specify IP Address and manually configure the IP address, subnet mask, and gateway according to your network settings.
6. Firewall or Security Settings
If the network has a firewall or security settings that block certain devices, ensure that the printer’s MAC address is whitelisted.
7. Update Firmware
Check if there’s a firmware update available for the Ricoh MPC C4504. Sometimes network connectivity issues can be fixed by updating the printer’s firmware.
8. Contact IT or Network Administrator
If none of the above steps work, the issue may be with the network configuration or a DHCP server problem. In that case, contact your network or IT administrator for further assistance.
These steps should help you troubleshoot and resolve the DHCP connection issue on the Ricoh MPC C4504.
