Certain Ricoh drivers when installed on OS X 10.5 or higher will give an error when trying to print. The error given will state that the "Printer software was not installed properly, please try removing the software and re-installing". This is caused by the driver's installer not setting the permissions correctly on an installed file on the computer. To resolve this issue you may follow the steps below.
Before beginning, you will need to remote into the users comptuer or have it physically in front of you. All of the steps required to fix this issue will be done through the "Terminal" app on the mac. If you are uncomfortable working from the command line/ terminal, you should ask for assistance from another who has performed this task before.
