Common Questions and Answers

IMPORTING IMAGES TO OTHER APPLICATIONS
Q1] Why do I sometimes get a black line across the top and bottom or along
the sides when I import images into PageMaker?
A1] These symptoms sometimes appear when an image is being saved as a TIFF
at 300 or 400 dpi line-art with a width exeeding 2 inches. For optimal
performance importing into PageMaker, save your FotoTouch images as TIFF
UNCOMPRESSED or PCX.
Q2] When I try to import FotoTouch documents into WordPerfect, why do I
sometimes get the message "Invalid File Format."
A2] This message is generated when trying to open a TIFF file generated
from FotoTouch. For optimal performance importing into WordPerfect,
save your FotoTouch images as TIFF UNCOMPRESSED or PCX.
Q3] How do I use ClipBoard in Windows to take a picture from FotoTouch to
Other Applications?
A3] Follow the steps below:
1. Scan an image and select an area to copy to the Clipboard using
the Selection Tool.
2. Select Copy from the EDIT menu.
3. Iconize FotoTouch. (Do not Quit or Image will be lost).
4. Bring forward the other Application and select PASTE from the EDIT menu.
This technique works with images which do not use more than 64K of memory
to store. For Images which use more memory than this, we recommend saving
the images to whatever format the target application will support.
PRINTING
Q4] Why is FotoTouch printing blank pages?
A4] There are a few possibilities:
1. Bitstream Facelift. See FaxBack document 2404.
2. Some non-Postscript printer drivers (notably Hewlett Packard) allow
you to choose a gray scale option under OUTPUT FORMAT. Selecting one of
these gray scale options (256 or 64 Gray Scale) will result in a blank
page. Choose Error Diffused or Dithered instead.
SCANNING
Q5] When I start FotoTouch, I receive an "Error Reading Drive D: (or E:)."
What is happening?
A5] FotoTouch comes with a built in Image Memory Manager (IMM) which works
independently of Windows' built-in memory manager. Whenever FotoTouch is
launched, it searches drives C:, D:, and E: for the drive with the most free
space in order to use this drive for temporary storage of images. This is fine
in most situations. However, if you have a non-hard drive (CD ROM, floppy
drive, etc.) designated as drive D: or E:, FotoTouch will be unable to read
from this drive.
To correct the problem, go into the WIN.INI file and insert the following
line in the [Logitech FotoTouch] section :
Temp2=drive:\directory
(For example, Temp2=C:\WINDOWS\TEMP)
This will instruct FotoTouch to use a specific drive and directory for the
temporary storage of images and will not do the automatic search.
Q6] When I select Acquire in FotoTouch, I receive "an error reading drive D:
(or E:)." What's wrong?
A6] Whenever you select Acquire from the File menu, you are actually leaving
the FotoTouch application and starting the ScanMan application. So the Temp2
line in the WIN.INI file won't work here because we are no longer in
FotoTouch. The problem is occurring for the same reason but there is a
different solution along the same lines. Go into the SCANMAN.INI file. About
14 lines down you will see the following line:
;Temp2Path=c:\tmp
Remove the leading semicolon (since this means this line is a comment in an
INI file) and change the drive and directory to a valid directory.
For example:
Temp2Path=C:\WINDOWS\TEMP
This will keep the ScanMan software from searching for a drive to use for
temporary storage.
COMPATIBILITY ISSUES
FotoTouch and the Intel SatisFAXtion Board
Version 2.10 of FotoTouch does not support the ScanMan 256 when plugged into
the Intel SatisFAXtion Card. If you are using the scanner in this
configuration and purchased FotoTouch as an upgrade, please make sure
you have version 2.11 of the software. To verify this version, look at the
last three digits of the serial number on disk 1 of the FotoTouch disks. If
it ends with 211, this is the correct version. If it ends with 210, an
upgrade will be needed. Please contact our Sales Information Services
at (800) 231-7717 to obtain further information about this upgrade.
FotoTouch and the Plus HardCard
The Plus HardCard requires a device driver in the CONFIG.SYS file and
uses IRQ 11, which will conflict with the scanner's default IRQ setting.
Symptoms include system locking when selecting Acquire and drive read errors
when selecting Acquire. The scanner must be set on another IRQ setting. Go
into the SCANMAN.INI file and change the interrupt setting (which is at the
bottom of the file).
PCTOOLS
PC Tools and PC Backup sometimes make changes to the Windows SYSTEM.INI
file which cause erratic behavior with the Logitech Scanner. The scanner
will typically work properly in Standard mode, but in Enhanced mode it will
generate an Unrecoverable Application Error in Windows 3.0, or will not
access the scanner in Windows 3.1.
Look for the following lines in the SYSTEM.INI file, in the [386Enh] section:
device=vfd.386
device=vdmad.386
If these lines exist, then PC Tools has replaced the Windows virtual floppy
driver and the Windows virtual DMA driver with another version. You can
reset Windows back to its own drivers by changing the lines to:
device=*vfd
device=*vdmad
This will disable the PC Tools backup program.
Central Point's Anti-Virus
If you run FotoTouch while Central Point's Anti-Virus program is active, you
will receive unexpected results. Some of the known error messages include
"Warning! TOUCH.EXE is Being Modified" and "Unexpected DOS Error 5." After
displaying the message, the Anti-Virus program will often lock up the
system. If you receive these messages, disable the anti-virus software when
running FotoTouch.
ATI Ultra and Vantage Video Cards
These are high performance 8514 compatible video cards. They come with a
wide variety of video drivers for Windows. One of these drivers is called the
Crystal Fonts driver. If you are using this driver you will receive colors
in the image instead of grays. If this occurs, select a different video
driver.
OS/2
In the OS/2 README file there is a listing of applications which are known
to be problematic or won't function under the OS/2 environment. Logitech
Ansel (now upgraded to FotoTouch) and Logitech Perceive are both mentioned
in this list of programs.
While the applications themselves seem to function under OS/2 2.0,
incompatibilities occur when accessing or using the scanner. It is simply
that the hardware device drivers written to support these devices were
written for the Windows 3.0 or 3.1 environment, not the OS/2 environment.
When we first contacted IBM about problems trying to scan with the ScanMan
256 in the Windows compatibility box of OS/2, they provided the following
reasons for this incompatibility:
- FotoTouch cannot work because of an incomplete implementation of OS/2 4B
interrupt. (create DOS thread)
- They issued a Corrective Action Request, and said they will correct it in
the next version.
- They have now a new version supporting the Windows 3.1 compatibility mode,
and it still does not support our software and scanner interface.
We have been in continuous contact with IBM and are currently working with
them to try to resolve this issue.
Logitech does not currently produce an OS/2 scanner or application. Apart
from working with IBM to resolve the incompatibilities within the Windows
compatibility box, we are also investigating the possibility of a scanning
product which will interface directly with OS/2. If you are interested in
seeing such a product on the market, please write and let us know:

Expanded Memory Managers (EMM386 and QEMM) and Standard Mode
On some systems, the presence of an expanded memory manager will conflict
with FotoTouch when run in Windows in Standard Mode. The symptom is that
no scanner activity is detected when you select Acquire. The optimum
solution is to run Windows in Enhanced Mode. If the computer will not
run in Enhanced mode, disable the expanded memory manager.
OTHER ISSUES
MicroChannel Machines (MCA)
If you are using a microchannel computer (PS/2 Model 50 and higher), but
are not using the ScanMan Model 256, you must have the most recent scanner
board along with FotoTouch. The application will not function with the
original microchannel board which accompanied the ScanMan Plus. To obtain
information about upgrading your microchannel board, contact our Sales
Information Services at (800) 231-7717.
Ami Pro Macro for FotoTouch
There are complete instructions on how to install the Ami Pro macro for
FotoTouch in the TOUCH.SAM Ami Pro document. For instructions on installing
this macro, we recommend reading (and printing out) the entire document.
For the Macro to work, FotoTouch must be running. If you plan on using
the macro, first start FotoTouch, then minimize it, then start Ami Pro.
The FotoTouch 2.1 macro will work with Ami Pro 1.2b and 2.0.
