CAUSE

These error conditions during printing may occur when third-party fax software is installed either on an Windows NT print server computer or on a computer running Windows NT Workstation.

RESOLUTION

Some fax software programs modify the registry. It might become necessary to remove the fax software in order to print. However, some programs do not clean up the registry when they are removed. Check the registry to see if there are entries added by a fax software program that might be causing one of the previous errors.

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

1. Start Registry Editor (Regedt32.exe) and locate the following key:

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print

2. Look for any entries that might be related to a fax software program.

3. Delete these entries. NOTE: Do NOT delete any of the subkeys of the Print key, such as Environments, Forms, Monitors, Printers, and Providers.
