3.4 Uninstalling the fax driver
3
Reference
- Even if you remove the fax driver using the above procedures, the model information file remains in the
computer. For this reason, when reinstalling the same version of the fax driver, the driver may not be
rewritten. In this case, remove the following files as well.
– Check the "C:\WINDOWS\system32\spool\drivers\w32x86" folder (for the x64 system,
"C:\WINDOWS\system32\spool\drivers\x64" folder), and if there is a folder of the corresponding model,
remove it. Note that if the PCL, PostScript, and XPS drivers are installed in addition to the fax driver, all
model information is removed. To leave drivers other than the fax driver, do not remove the folder.
– From the "C:\WINDOWS\inf" folder, remove "oem*.inf" and "oem*.PNF" ("*" included in the file name
indicates a number, which differs depending on the computer environment).
Before removing these files, open the inf file, and then check the model name described on the last few
lines to confirm it is the file for the corresponding model. The number of the PNF file is the same as that
of the inf file.
– In Windows Vista/Server 2008, this operation is not necessary if you have selected "Remove driver and
driver package".
