17-Character File Name Limitation
This file name limitation applies to half-tone pattern names, as well as setting names (for example, Untitled Pattern 2). To work around, delete any setting names or half-tone pattern names that exceed the limit. Also, the system error occurs only when saving the file in PICT format.
Background Printing
Background printing of scanned images under MultiFinder may produce "streaks". This applies not only to AppleScan, but also to other applications that print scanned images. It is recommended that background printing be turned off whenever printing a document that contains scanned images.
Printing Scanned Half-Tones
In general, printed output of scanned half-tones looks best when the Graphics Smoothing, Faster Bitmap, and Precision Bitmap print options are turned off. Again, this applies to most applications. Use LaserWriter Driver 5.2, which is included on the AppleScan disk and the System 6.0 Printing Tools disk.
HyperScan
When starting HyperScan, a "Can't load Global variables" dialog may appear, preventing use of the stack. This occurs in extremely low memory situations on 1MB machines. Try turning off the RAM cache. If the problem persists, it may be caused by an INIT (or several INITs) using memory.
