Troubleshooting 109
The printer does not print normally via the network interface (only for the 
DN model)
For Windows users only
The Data Format setting in the printer’s Properties is 
not set to ASCII or TBCP.
The printer cannot print binary data when it is connected to 
the computer via the USB interface. Make sure that the Data 
Format setting, which is accessed by clicking Advanced on the 
PostScript sheet of the printer’s Properties, is set to ASCII or 
TBCP.
If your computer is running Windows Vista, Vista x64, XP, XP x64, 
click the Device Settings tab in the printer’s Properties, then 
click the Output Protocol setting and select ASCII or TBCP.
Cause What to do
The Data Format setting is different from the data 
format setting specified in the application (except on

If the file is created in an application that allows you to 
change the data format or encoding, such as Photoshop, 
make sure that the setting in the application matches that in 
the printer driver.
For Windows users only

AppleTalk in a Windows 2000 environment, and the 
Send CTRL+D Before Each Job or Send CTRL+D After 
Each Job setting on the Device Settings sheet of the 
printer’s Properties dialog box is set to Yes.
Make sure that both the Send CTRL+D Before Each Job and 
Send CTRL+D After Each Job settings are set to No.
