Q:

Which SCSI card on Panther?

A:

Please remember to always turn the scanner on before you start your computer. The scanner can not be recognized if it is turned on while the computer is running. A reboot with the scanner on is required in this case.

For running SilverFast successfully it is necessary the OS detects the scanner. You can check in the Apple System Profiler whether it could.

Acard 6712TUM (G3, G4) and 67160M (G5) have proved the most compatible SCSI controller cards under Mac 10.3.2 and higher. Please update 10.3.0 and 10.3.1 in any case.

Also think about firewire-to-SCSI converters such as the Belkin FS451U or the Ratoc FR1SX. These have been used by our testing personnel quite successfully with certain Umax, Linotype and Howtek scanners.

Q:

General SCSI checklist
Please go through the below checklist before you contact LaserSoft-Imaging support.

A:

- was the scanner switched on BEFORE starting the computer? (essential in MS Windows and OS X) - is the SCSI termination correct (only last external device on bus)?
- is the SCSI ID correctly set ( between 2 - 6)?
- is the SCSI ID occupied by another SCSI device? Each device needs a unique SCSI-ID - is the cable length correct? (max. length:1,5m = one external device; 3m = several devices)
- what SCSI card model is installed in your computer? Please do NOT use very fast SCSI cards (Ultra Wide or Ultra2 Wide) as such cards are designed to run hard drives, and can cause problems when being used with slower devices such as scanners. - did you try to put your SCSI card into another slot?

Macintosh
SilverFast can ONLY communicate with a device on OSX, if this device is found on its bus in the Apple System Profiler (devices and volumes).

Windows
All: use the right ASPI driver: go to the german URL www.aspi-treiber.de and youテ「テモテモ冤l find in section テ「テモテモ哂SPI-Layerテ「テモテモ the correct ASPI Layer driver for your SCSI card and your system.

Umax: Astra 4000u is NOT supported on Windows 2000
Umax: Microsoft systems install a default INF file for Umax devices. SilverFast will NOT work with Umax devices when the Microsoft hardware assistant installed the device using those generic Umax INF file. Please delete this device entry from the Windows device manager, install the Umax scan software using their INF file (on CD) and ONLY then SilverFast can communicate with the Umax scanner.

SCSI Bios: (if applicable)
data transfer rate not too fast at scanner's ID? (5M/sec is lowest)

Please check whether you can do a scan using the manufacturer's original scan software, and send your answers to the above questions along with the "SF_logfile" to support@lasersoft.de or to info@silverfast.com if you live in North or South America.

Q:

Macintosh OS
SCSI device connected and on SilverFast launch my blue/white Macintosh machine issues error messages like: "could not find connected devices..." or "no scanner found...". What can be the reason?

A:

please go into the 'Apple System Profiler' (ASP):
- on Desktop, main menu, expand the Apple, and select Apple System Profiler. The ASP will open
- go to the 2nd tab devices and volumes, current communication busses and peripherals will be listed. - verify under SCSI whether you can see an entry for your SCSI card.

If the SCSI card is there, check whether you can also see an entry (under SCSI) for your scanner. If the SCSI card is not there: - make sure you have the appropriate driver installed for your card (Mac OS includes drivers for some cards like the Adaptec 2930CU, but an external driver might be required if you use a different model) - shut down computer
- switch off the scanner
- plug the SCSI card into another PCI slot
- switch the scanner back on
- restart computer and check the ASP again for an appropriate entry for your card AND for your device.

Q:

SCSI on OSX: ...not found...
SilverFast error message: "no scanner found..." although your web site says that my SCSI scanner is supported on OSX, what can I do?

A:

Please check the Apple System Profiler first (Applications > Utilities). Make sure the scanner is listed in the section "Devices and Volumes". If the scanner is NOT listed there as a SCSI device, the system didn't recognize the scanner and - of course - SilverFast will never find it.
This is a SCSI conflict on operating system level. Changing SCSI ID, cable, PCI socket, or SCSI card might help in such cases. Also check the SCSI card manufacturer's web site for OSX drivers.

Q:

OS X bad SCSI cards
SilverFast hangs or crashes the entire OS X system when I attempt to run a prescan or scan. Is this normal?

A:

we found that running a SCSI scanner through Acard 6712 and Advansys 3030 may run into problems on OSX systems when scanning large scan areas (A3) or large image files.
The OSX SCSI card drivers cannot handle large amount of data requests which might end in a frozen or crashed application.

Q:

OS X unsupported SCSI cards II
LinoScan 2200 and Umax 2100XL in combination with Adaptec 2906 SCSI card is not feasible!

A:

LSI quality confims that the hardware comination:
LinoScan 2200 and Adaptec 2906
or
Umax 2100XL and Adaptec 2906
used on OS-X systems will not work with SilverFast! The scanners were never found by the system. However, swapping SCSI card for an Acard 67xx solved the 'scanner not found' issue immediately.

Using the Belkin FireWire- SCSi converter also produced good results here. Another workaround that may work is to shut-down computer, switch off scanner
then switch scanner back on and restart system. Make sure "term power " and "termination" are both turned on.

Q:

OSX 10.2.1
SCSI scanners not found on OS 10.2 with SilverFast latest release of version 6.

A:

In many cases it helps to update the operating system with the Jaguar patch to release 10.2.5 or higher!

Q:

Agfa/Umax firewire on OS X -
The manufacturer scan software works perfectly on OSX, but SilverFast cannot find the scanner, what can I do?

A:

Agfa f40 and Umax Powerlook 1120/1100 will NOT work with SilverFast on OS-X when the manufacturer scan software is installed. Manufacturer scan software will install a kernel extension and prevent SilverFast from communicating with the device.

Q:

classic
On Macintosh with PolaroidSS4000 resp. SS120 device connected through SCSI.
On launching SilverFast the program might issue error messages such as:
テ「テモテモ彡ould not complete import command, because an error occured"
or
テ「テモテモ could not complete import command, because of a problem with the code fragment manager"
What can be the cause?

A:

These messages are due to the FireWire and USB extensions that Silverast Ai 5.5.2 installs on Macintosh systems.
Please either connect your device as FireWire (or USB) or disable the following extensions in your System Extensions:
Polaroid SSFWDriver
Polaroid SSFWExpert
Polaroid SS4000FWDriver
Polaroid SSUSBDriver
Polaroid SSFWFamily

Q:

OS X on grey Macs -
My SilverFast OSX version does not find my SCSI scanner. Any hints on this?

A:

If the OSX system is installed on a Macintosh with on-board SCSI bus (beige case machines), the OSX system does not detect connected SCSI scanners correctly. Thus SilverFast won't find any known devices.
Solution:
plug a SCSI host adapter (PCI card) to your Mac and connect the scanner to that card.

Q:

Tekram SCSI on Windows XP -
SilverFast quits or simply freezes on Windows XP upon prescan whereas the manufacturer software works fine. What is the problem here?

A:

This is a compatibility problem between the SCSI card and the ASPI layer drivers used.

SilverFast installations as early as version 5.5 usually install ASPI layer files (ver 4.71.2) on a Windows system.
LaserSoft Imaging quality control discovered that a Tekram (395u) card will NOT function properly when ASPI drivers in version 4.71.2 are in the system.
Installing ASPI Layer drivers version 4.6 will cure the problem.

Q:

ISA bus SCSI cards, Windows -
SilverFast has problems finding a SCSI device that is connected to a ISA SCSI card.

A:

If your main board features on-board serial port(s), please set it/them to "disabled when you have a ISA card plugged to your main board.
Why this?
the IRQ request of that on-board serial port(s) conflicts with the IRQ request of the ISA card.
- please verify in your computer's BIOS in the section integrated peripherals whether the option on-board serial port (n) is/are disabled.
Also:
in the computer's BIOS, go to section chipset features and set the option Memory hole at 15M - 16M to "enabled"
why?
this will reserve certain space in memory for ISA cards. This memory must be mapped into the memory space below 16Mb (therefore the naming 15M - 16M).

Q:

Windows 98, SCSI -
My SCSI Scanner is not seen neither by SilverFast nor by the manufacturer's software.

A:

Windows 98 does not support sharing of system interrupts between two or more I/O subsystem devices (i.e. network interface cards or hard disk adapters such as SCSI host adapters). When IRQs are shared between I/O devices, lockups can occur while booting. If lockups occur, try moving or removing one or more PCI cards from one slot to another and bootup your computer again. If problems continue, try removing all but the necessary PCI controllers from your main board and start over again.

If nothing helps, please send us information from the Microsoft systeminformation:
Go to the Windows "Start" menu > "run" and type "Msinfo32", the MS information window appeares (similar to explorer).
in the left window go to HW Resources then Conflicts/sharing and IRQs ,

Q:

Windows 98 systems
SilverFast won't find a scanner on Win98 whereas the manufacturers scan software has no problem communicating.

A:

If that Windows computer has a CDwriter installed, unplug this device from the computers main board. If SilverFast then finds the scanner with out problems, there are various permanent possible remedies:
- some main boards (above all those with Via chip sets) need driver updates for their chipset.
- machines with more than one hard disk may accept a swapping of Master /Slave configuration of the installed physical drives.
- some CDwriters may require a firmware update.

Q:

Applies to Linotype scanners, which are connected to a LSI logic or Symbios SCSI card under Windows
SilverFast can not recognize the scanner in windows, or in the middle of the scan everything stops.

A:

Update the drivers for the SCSI card (aspi) from the SCSI card manufacturer's website.

Q:

Recommended SCSI solutions for Umax and Linotype scanners in OS-X

A:

We recommend the following SCSI cards:

for G3/G4 computers: Acard AEC-6712 TUM
for G5 computers (PCI-X): Acard AEC-67160M

a FireWire- SCSI converter (Belkin) can also be used on most Umax and Linotype scanners, however this solution might not allow batch scanning.
We do not recommend using any Adaptec cards with these scanners in OS X Panther, as Adaptec canceled support for Mac OS altogether, cf. Adaptec Knowledge Base Answer ID 11052.
