   Sumovmi.386 from Panasonic KXP-6100 laser printers
   Vcpd.386
   Vecpd.386 from Netscape Navigator

RESOLUTION

To resolve the problem, follow these steps:

  1. Click the Start button, and then click Run.

  2. Type the following line in the Open box, and then click OK: 

          system.ini

  3. Locate any of the following lines in the [386Enh] section of the file, and then remove or disable the lines: 

        - DEVICE=<path>\Cis1284.386
    - DEVICE=<path>\Lex01.386
    - DEVICE=<path>\Okiport.386
    - DEVICE=<path>\Sumovmi.386

    NOTE: To disable a line, place a semicolon (;) at the beginning of the line.

  4. On the File menu, click Save.

  5. On the File menu, click Exit.
