3.6 Manually uninstalling the printer driver 3
Tips
In Windows Server 2003, if the printer driver is uninstalled in the above procedure, the model information files
remain on the computer. For this reason, when reinstalling the same version of the printer driver, the driver
may not be rewritten. In this case, remove the following files as well.
- Check the "C:\WINDOWS\system32\spool\drivers\w32e86" folder ("C:\WINDOWS\sys-
tem32\spool\drivers\e64" folder in the e64 system), and if there is a folder of the corresponding model,
remove it. However, if multiple drivers are installed including the PCL KONICA MINOLTA driver, Post-
Script KONICA MINOLTA driver and fax driver, the model information of all drivers is deleted. 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.
- If you have deleted a file using [Remove driver and driver package.] in Windows Vista/7/8/8.1/Server
2008/Server 2008 R2/Server 2012/Server 2012 R2, this operation is not required.
