Software Installation Problems
If you have problems while installing your product software, try these solutions:
• Make sure your product is turned on and any necessary cables are securely connected at both ends. If
you still have problems installing software, disconnect the cable and carefully follow the instructions on
the Start Here sheet. Also make sure your system meets the requirements for your operating system.
• Close any other programs, including screen savers and virus protection software, and install your
product software again.
• In Windows, make sure your product is selected as the default printer and the correct port is shown in
the printer properties.
• If you see any error message or your software does not install correctly in Windows, you may not have
software installation privileges. Contact your system administrator.
