Here are some troubleshooting tips to try:
- There is an issue with the Fax Terminal quitting with a Type 1 error when using System 7.5 Update 2.0 and Apple Guide 2.0.2. Allegedly, Apple Guide 2.0.2 can be installed on a computer with System 7.1 which may be distributed with some software packages such as Newton Press and Quicken. Also, the Apple Internet Connection Kit (AICK) 1.1.1 comes with Apple Guide 2.0.2. If you have this extension installed, try removing it from the Extensions folder.
- If the above is not affecting the computer, try performing a clean system installation since you have already thrown away the preferences files. We have found that corrupt preference files may also cause this.
- Try removing previously sent or received faxes from the folder. A corrupted file in the files sent or received folders may be causing this.
- Try using only Apple extensions in the Extensions Manager control panel. Note: Were any software or hardware changes made just before the issue started?
