Hi I have using fuji XeroX M225dw and after updating MaxOS Catalina , no more working with iMac driver , what would I should do ,Hope someone can help
Most likely Apple replaced the driver with one of their own. They do this often with major updates.
Which then means you have to go to the manufacturers webpage and download the official drivers to make them work again.
In your case that would be FujiXerox.com (not Xerox.com)
