Technical Support
Technical Support is available world-wide. Please refer to your point of purchase for the appropriate con-
tact in your area.
When calling for assistance, please have the following information readily available:
• Your phone number, fax number and shipping address.
• A description of the problem.
• The printer model.
• The type of host computer you are using.
• The type and version of operating system you are using.
• The application and version you are using.
• The interface you are using (e.g., network, parallel, serial).
• If using the network interface, the network protocol (TCP/IP, EtherTalk, IPX/SPX, NetBIOS/Net-
BEUI).
• The printer emulation you are using (e.g., PCL or PostScript).
• A printout of your printer’s Configuration Summary. (Refer to your printer’s User manual).
• If you have a printer hardware problem you cannot resolve, provide the error message displayed on
the Control Panel. For a list of error messages, refer to your printer’s User manual.
NOTE: To confirm that a problem is isolated to the RS-232C/RS-422 Serial Interface, you may want to
remove the serial interface from the printer and diagnose the printer using the User’s Manual that
came with your printer. If the condition persists, it can be assumed that the problem resides within
the printer and not necessarily the serial interface.
