If you receive an "Illegal Operation" or Exception error 10H message from Windows when performing
routine printing tasks in our products, there are several things that you can
do to try to eliminate this error:
If you receive the "Illegal
Operation" error click on the DETAILS button. If you get a message similar
to the following:
"ExpWin" caused an exception 10H in module ExpWin.exe at XXXX:00######"
You may have an incompatibility between
our program and your printer driver.
We have found this particularly to
be the case the following printer drivers:
- Canon BubbleJet BJC-70
- Canon BubbleJet BJ-210
- Canon BJC-610
- Canon BJC-4000 Windows 3.1 driver version 1.0d/3.1
- Canon BJ-200EX
- Canon BJC-4100
- Canon BJC-4200
- Eclipse Fax driver
- Hewlett-Packard (HP) DeskJet 660
- Hewlett-Packard (HP) DeskJet 660c driver versions prior to 8.0
- Hewlett-Packard (HP) LaserJet 5L
- Hewlett-Packard (HP) LaserJet 5P/5MP
- Generic/Text Only
- MidiComm Fax Driver by MidiSoft
- Cheyenne Bit-Fax
- Epson Color Stylus, especially the 600/700 series printers.
If you are getting this error message,
the printer driver you are using should not be set as the default printer when
the application is printing. Setting another printer as the default printer
and then switching to your specific driver using PRINT SETUP may get you around
the problem, but it may not help.
Your best option is to print to another
printer or use a compatible printer driver such as the LaserJet 5P driver or
download the updated driver from HP, in the case of the HP LaserJet 5L. For
Cannon BubbleJet Printers try the IBM ProPrinter drivers. Often times compatible
drivers will be listed in the printer manual.
Additional information about this issue
can be found at http://www.microsoft.com
by searching the support knowledge base. The 10H error is a floating point processor
(math processor) exception. Faulty printer drivers are now infamous for mistakenly
causing this error.
AS A LAST RESORT (NOT recommended) . . . if changing the printer driver to a
compatible driver does not stop the crashing problem, you may try turning off
the Math coprocessor. To do this follow these directions:
- With your right mouse button, click My Computer, and then click Properties.
- On the Device Manager tab, click View devices by type.
- Double-click System Devices.
- Click Numeric Data processor, and then click Properties.
NOTE: With a Plug and Play bios, the
Numeric Data Processor option will be under a Plug and Play branch in the
Device Manager rather than at the top level.
- On the Settings tab, click Never Use The Numeric Data Processor.
- Click OK.
- Restart your computer.
