How to fix the DHCP connection error on a Ricoh copier

Ricoh MP C5000 copier



These days, office copy machines are more often used as multifunction printers (MFPs) than stand-alone copiers.  However, if your copier is not connected to a network, it may flash this DHCP error in the lower left corner of the display screen:

Cannot connect with DHCP server. (101)
Contact the administrator.

Although that message doesn't necessarily indicate that something is "wrong" with the copier, you can easily clear it by following the steps below.  This guide was written for modern Ricoh MP series copiers; for older Ricoh copiers without a color touch screen, the basic fix is the same but some of the tabs and buttons may be labeled differently.

Please note: If the copier is connected to your local network, contact your network administrator before changing any network settings.

  • Press the User Tools button on the copier's operation panel (typically located to the upper left of the display screen).
  • On the touch screen, tap System Settings (in the upper left corner of the screen).
  • The System Settings section is broken into tabs; tap the Interface Settings tab.  (On older copiers, this tab may be called Host Interface.)
  • Tap Machine IPv4 Address.
  • There are two options here: Auto-Obtain (DHCP) and Specify.  (The first option should be the active one.)  Tap Specify to turn off DHCP, so the copier won't try to obtain an IP address.
    • It doesn't matter what IP address you specify, since the copier isn't connected to a network.
  • Tap OK to save the change.
  • Press the User Tools button again to exit out of the menu.

The DHCP error message should disappear within a few moments.  If it doesn't, turn the copier off and then back on and it will go away.
