PRB: Cannot send fax. "Parameters too long" in server log



ID: ZTN1521

This Zetafax technical note applies to:

  • Zetafax 8 onwards


A user cannot send faxes and the Zetafax server shows errors:

EPSTIFF           - (E) - Parameters too long
QUEUEMAN     - (E) - Error converting message (0xF212)


Zetafax accepts Zetafax usernames that have a maximum of 8 characters, with no dots, spaces or special characters.

Therefore Zetafax usernames with dots or spaces will cause the errors above. When Zetafax users are added manually (Zetafax Configuration Program - Zetafax users - Add new Zetafax user), you will be prompted if the username is invalid with the following message:

Zetafax setup error!

Username invalid - use only A-Z, 0-9, '_' or '-'

However when Zetafax users are created by enabling NT users from Active Directory, usernames are not checked for validity.

Note: Usernames are automatically truncated if they contain too many characters.


Zetafax usernames must only contain A-Z, 0-9, '_' or '-'.

You should recreate the Zetafax username with only these characters i.e. no dots, spaces or special characters.


This has been identified by Equisys as a problem with the software versions given above.
