PRB: Zetafax client does not detect TWAIN scanner



ID: ZTN1058

This Zetafax technical note applies to:

  • Zetafax 6.01g client


Zetafax 6.01g client does not enable the 'Acquire' button even though a TWAIN scanner is installed on the client.


In previous versions of Zetafax clients, the scanner "acquire" button was automatically enabled if TWAIN drivers were installed on the computer.  With Zetafax client version 6.01g it is not.


The workaround for this fault is accomplished by editing the registry of the Zetafax client computer, detailed below.

  1. Close the Zetafax client.
  2. Run REGEDIT (using Run from the Start menu)
  3. Navigate to HKEY_CURRENT_USER\Software\Equisys\Zetafax\Client
  4. Add a new string using Edit> New> String Value (or change the existing value if already present)

Value name:


Value data:


  1. Close REGEDIT and start the Zetafax client.


This has been identified by Equisys as a fault only with the programs listed at the beginning of this note.  It is not present in older or newer versions.
