There can be many reasons for the CPU utilisation being high.
One could be when there is broken or corrupt file in a hot folder which the system is trying to pick up for processing but cannot - if this is the case, check all the hot folders and make sure there is no files in them. It also could be network related issues when talking to printers, in this case disable the printers in the printer management and see if CPU utilisation goes down.
To analyse the issue further, please contact your Xerox support, who will be able to investigate the root cause.
