- Beware the SCSI chain flaking out or the scanner overheating (at "104" degrees
- _internally_, e.g., 90 degrees room temperature (the scanner is self-heating
- since it has an internal fluorescent bulb which is always on when the scanner
- is on)). In my experience, either of these problems while using PowerScan
- reduces your NeXT to a hung PC --- it hard core hangs (all applications freeze,
- menus won't activate, keyboard is ignored; I believe even the NMI keys don't
- work!).
-
- I get the impression the scanner or PowerScan is/are (somehow) hanging the SCSI
- bus (thus effectively disabling all SCSI devices, including the hard disks
- :-(). I think this problem causes all unsaved and unsync'ed (by the OS) work
- to be lost --- even that of other applications or any background processes.
- Needless to say, PowerScan does not deal gracefully with scanner SCSI
- communications problems.
-
- So, now before using PowerScan, I disconnect my modem (so I don't lose incoming
- information, e.g., e-mail), and save all my work in other applications. Of
- course, now my NeXTstation becomes no more than a flakey, single-tasking PC,
- but so it goes to use my scanner... Also, I leave my scanner off when not in
- use.
-
- I reported this problem to HSD (most recently on 20 October). I have no idea
- what (if any) progress is being made to solve it.
-
- If anybody can shed more light on these problems (or even has solutions, heaven
- forbid :-), please let me know!
-
- Thanks,
