Has anyone experienced how slow the WC7535 is when used as an iMFP device.The printer was upgraded to the latest firmware version: 061.121.224.27301. The minimum required being 0.61.121.222.21500.. The printer seems to have connection issues especially when the server becomes busy. It takes more than 30 sec just to create a session and takes additional 24 sec to login the user provided it did not show the “Communication Error” screen. When the user finally manages to login the printer takes additional 2 minutes just to spool the print job. In some cases the printer needs to be rebooted completely before users can login.
I recommend that you upgrade the iMFP software to the latest version and see if that resolves the issue
