Printing Problems (Network Related)
Among the several ways to use the equipment in the network, the simplest one is to set the equipment in the TCP/IP environment 
using a DHCP server to assign IP addresses dynamically to devices. Using the default settings also assures an easier network 
implementation, although you may be required to customize the settings to accommodate them in your particular environment.
Some common network configurations are shown below, along with the steps required to configure the equipment. If you perform all 
the steps in the applicable checklist and still cannot print satisfactorily with the equipment, contact your dealer.
Memo
• You can change the network protocol settings with the touch panel of the equipment or with TopAccess (the Administration page).
• For the error messages that appear during the installation of the printer drivers, refer to the Basic Guide.

setting referring to the TopAccess Guide.
5 When IPv4 is supported: If the client computers are 
located in different segments, is the WINS service 
correctly provided?
Next Step
When IPv4 is supported: Set up the WINS server and 
enable it on the equipment to allow users access from a 
different segment.
