We are currently testing Mobile Print but having an issue with the Sharp Color MX3115 not printing BW. The print outs either come out blank or are illegible. Mobile print will print in color via Pharos Web Release and email submission just fine for some reason but not BW. Just wondering if anyone was having similar issues with their Sharp MFPs. I've already tried to add the specific drivers for the Sharp including PCL6, PS, PPD, and the Universal Sharp driver, none seem to correct the issue.
